3. WindirStat

Are you struggling with disk space on your Windows system? It’s time to bring in WinDirStat, the ultimate disk usage statistics viewer and cleanup tool designed to help you reclaim valuable storage space on your PC. Whether you’re using Windows XP, Vista, 7, 8, or 10, WinDirStat has got you covered.

But what if you’re a Linux or MacOS X user? Fear not, there are alternatives like KDirStat for Linux and Disk Inventory X or GrandPerspective for MacOS X users. Each of these tools serves the same purpose of providing insights into your disk usage and helping you clean up unnecessary files.

Key Features of WinDirStat

Upon startup, WinDirStat performs a comprehensive scan of your entire directory tree, allowing you to visualize your disk usage in three distinct views:

1. Directory List: Similar to the tree view in Windows Explorer, but sorted by file/subtree size, making it easier to identify which files and folders are taking up the most space.
2. Treemap: This innovative visualization tool presents the entire contents of your directory tree in one glance. It represents each file by a colored rectangle, with the size of the rectangle proportional to the file’s size. It represents directories by larger rectangles containing their files and subdirectories, giving you a clear overview of your disk space usage.
3. Extension List: Acting as a legend, the extension list provides valuable statistics about file types, helping you understand which types of files are consuming the most space on your disk.

Disadvantages

The Treemap while praised by some could be a real pain to read and understand. Looking at the pie and graph charts of the top disk analyzers is way easier. The lack of the largest files and largest folder reports makes it hard to locate the missing disk space. The user interface is quite archaic from the ages of Windows 95.

How WinDirStat Works

The treemap feature is particularly noteworthy, as it offers a unique and intuitive way to visualize disk usage. Each colored rectangle represents a file, with its size directly correlated to the file’s size. By organizing files into rectangles, WinDirStat effectively showcases the directory structure, making it easy to identify large files and folders at a glance.

Moreover, the color of each rectangle corresponds to the type of file, as indicated in the extension list. This visual representation allows you to quickly identify which types of files are dominating your disk space.

Conclusion

With WinDirStat, taking control of your disk space has never been easier. Its intuitive interface and powerful visualization tools empower you to identify and remove unnecessary files, freeing up valuable space on your Windows system. Whether you’re a casual user or a power user, WinDirStat is an essential tool for maintaining a clean and organized disk.

5. Disk Space Scanner

Utilizing a sunburst chart, this tool illustrates the utilization of your hard disk or other storage media. The chart comprehensively displays all significant files and folders across various directory levels simultaneously. Each section provides information upon mouse-over, and you can click on any of the pie sections to redraw the pie, using it as the ‘root’.

Картинка с сайта: www.mindgems.com

Disk Space Scanner

Scanner by Steffen Gerlach is an interesting little tool. While you might like the sunburst type of disk visualization, it provides very limited features. The information is not visible at a glance and you have to hover the chart to display it. This is rather inconvenient and could be quite annoying.

There is no list of the folders and files or any kind of filtering options. There are no additional disk usage reports either. Overall it is an interesting tool. Unfortunately, its functionality is quite limited. If you are looking to view your disk space usage with a sunburst chart you might find it useful.

The tool is very archaic with its latest version 2.3 dating back to the year 2000. Yet it still works on Windows 11 and you can use it for free.

DUA Disk Space Analyzer Features and Limitations

Let’s delve into why there’s only one available backend for Dua. Previously, there was an option to use termion as a backend. However, maintaining both backends became more burdensome than it’s worth and added complexity that I didn’t find appealing anymore. While termion had its benefits, I was never fond of the fact that it seemed to have dropped out of support. As a result, crossterm emerged as the sole remaining backend, and it’s actively developed, ensuring stability and reliability.

However, it’s important to acknowledge some limitations of Dua:

• It doesn’t display symbolic links if no path is provided when invoking Dua. To address this, symbolic links are currently pruned and not used as a root. They will be shown if they are not a traversal root but will not be followed.
• Interactive mode may only look good in dark terminals, as highlighted in this issue.
• File names in the main window are not truncated if they are too large, resulting in them being cut off on the right.
• Certain examples in tests/fixtures may not render correctly in interactive mode due to graphemes not being interpreted correctly. This issue is particularly noticeable with Chinese characters, where column sizes are not accurately computed, leading to certain columns not being shown. Terminal discrepancies may also occur, such as with alacritty, which performs worse than iTerm3 in some cases.
• In interactive mode, approximately 60MB of memory is required for 1 million entries in the graph.
• The maximum amount of files in interactive mode is limited to 2^32 – 1 (u32::max_value() – 1) entries. This limitation is due to the underlying petgraph crate, which considers it unsafe to use u64. Although reaching this limit might result in undefined behavior, it has not been observed thus far.

DUA Conclusion

If you are familiar with consoles, scripting, and development then you might find DUA useful. Unless you are prepared for challenges you better stick with a tool from the top positions of our list. This tool is not fit for the average user and requires advanced skills. Even if you have such skills it is not worth the effort installing and using it. That is because it does not deliver anything special to the stage.

Отсутствие свободного места на жестком диске — проблема постоянная. С покупкой более вместительного носителя она не решается, а лишь усугубляется: чем больше накапливается информации, тем сложнее ее контролировать и при этом соблюдать некий условный порядок.

Существует немало утилит для поиска дубликатов, устаревших и других ненужных файлов, однако сервисное обслуживание диска не избавляет от необходимости самостоятельного «разбора завалов». Эти файлы, как нередко бывает, хранятся в папках различных уровней вложенности. Использовать для поисков инструментарий файлового менеджера — один из вариантов. К слову, даже стандартный Проводник имеет в наличии фильтр и поиск. Однако есть более эффективные, комплексные решения для анализа дискового пространства. Как правило, они включают в себя такие функции, как:

• Сканирование дисков и каталогов
• Визуализация данных: отображение файловой структуры в виде диаграммы, графика или карты
• Расширенная статистика и ее экспорт
• Поиск дубликатов, временных файлов
• Фильтры и расширенный поиск
• Дополнительные инструменты

Сегодняшние участники путеводителя — преимущественно бесплатные программы. Исключение составляют FolderSizes и TreeSize, хотя последняя предполагает и бесплатную версию в редакции Free. В результате список участников выглядит следующим образом:

• TreeSize
• Scanner
• WinDirStat
• Space Sniffer
• JDiskReport
• Xinorbis
• FolderSizes

TreeSize Pro

Домашняя страница: http://www.jam-software.de/treesize/

TreeSize — утилита для поиска файлов, нерационально отнимающих дисковое пространство. Включает в себя как информационные функции (визуализация, статистика, экспорт), так и сервисные: поиск дубликатов, устаревших файлов и т. п.

Картинка с сайта: www.ixbt.com

В левой панели окна TreeSize расположено меню выбора дисков и древо каталогов, где осуществляется навигация и выбор источника сканирования.

Результаты отображаются в правой части окна, состоящей из вкладок. В разделе Chart доступна диаграмма, из которой можно узнать процентное соотношение каталогов внутри выбранного источника. Также несложно сменить отображение данных в виде графиков либо карты. Подробная информация о каталоге (количество данных, занимаемое пространство и т. п.) доступна во вкладке Details. Extensions —распределение данных по их содержимому: видео, графика, текст и другие. В Age of files — информация о возрасте файлов. В дополнение будет полезным проанализировать хронологию заполнения диска (History). Все данные доступны для экспорта в XLS, CSV, HTML, TXT и других форматах.

Top 100 содержит список самых крупногабаритных файлов на диске. Сопутствующая информация в колонках таблицы позволяет узнать дату последнего доступа или создания файла — это поможет принять решение: удалить или оставить файл.

Картинка с сайта: www.ixbt.com

Не меньший интерес в TreeSize представляют собой поиск (меню File Search). Можно задействовать все типы данных (All Search Types): сюда, в частности, входят поиск устаревших, временных файлов, дублей. Преимущество поиска через TreeSize неоспоримо: программа многопоточная, работает по сети, поддерживает шаблоны.

Увы, бесплатная (по сути — ознакомительная) версия TreeSize существенно проигрывает платной: не поддерживаются многопоточность, расширенный поиск, визуализация и многие другие важные функции.

Резюме. TreeSize Pro отлично дополняет возможности любого файлового менеджера, позволяя тщательно провести анализ занятого пространства дисков и каталогов. Хорошо настраиваемый интерфейс и поиск, визуализация, экспорт — стандартный набор в комплекте.

[+] Функциональность
[+] Расширенный поиск файлов
[+] Быстрое многопоточное сканирование
[+] Дополнительные инструменты

Scanner

Домашняя страница: http://www.steffengerlach.de/freeware/

Scanner — бесплатная утилита для анализа содержимого жесткого диска. Отсутствие настроек, минимум опций — тем не менее, Scanner представляет собой вполне функциональное решение.

В левой части окна доступен выбор диска для анализа, также можно получить информацию в имеющихся файлах на всех дисках с помощью кнопки «Суммарно» в левом нижнем углу.

Картинка с сайта: www.ixbt.com

В центре находится круговая диаграмма, которая отображает файловую структуру в виде сегментов. Сегменты, как легко отметить, имеют несколько уровней вложенности и различный цвет. При наведении курсора на определенный участок диаграммы, доступна информация о количестве, размере файлов, место их расположения. Можно переместиться в каталог, кликнув по нему, либо произвести операции с файлом через контекстное меню.

Резюме. Программа будет полезна для быстрого зрительного анализа занимаемого дискового пространства. Что касается доступных операций с файлами и каталогами — их достаточно лишь для удаления и открытия файлов. Другими словами, использовать Scanner как файловый менеджер (с поиском, режимами отображения, статистикой) не удастся.

[+] Легкость использования, интуитивность
[−] Минимальное количество файловых операций

WinDirStat

Домашняя страница: http://windirstat.info/

WinDirStat — бесплатная утилита для анализа и очистки жесткого диска от ненужных файлов.

Программа сканирует указанные источники (каталоги или локальные диски) и предоставляет информацию для анализа в удобном для ознакомления виде. Структура каталогов отображается в виде разноцветных сегментов различного размера, в соответствии с занимаемым пространством, в нижней части окна WinDirStat. Таблица соответствий цвета типу файла находится в правом верхнем углу.

Картинка с сайта: www.ixbt.com

В подобном представлении структуры есть свои недостатки: скажем, нельзя узнать размер файла при наведении, отсутствуют пометки. Поэтому в случае с WinDirStat не хватает альтернативных способов визуализации, таких как график и диаграмма.

Щелкнув по сегменту, можно получить детальную информацию о соответствующем файле и его расположении. С файлами доступны такие стандартные команды, как удаление (в Корзину либо безвозвратное), просмотр свойств, копирование пути и другие. В разделе «Очистка» настроек программы предусмотрено создание пользовательских действий, позволяющих добавить до 10 операций из командной строки: удаление файлов, архивация, рекурсивное удаление и прочие.

В целом, почти все настройки WinDirStat сводятся к оформлению, отображению структуры и списка каталогов. Каких-либо дополнительных утилит, инструментов для отчетности, статистики, поиска здесь не предусмотрено.

Резюме. В WinDirStat представлены неплохие возможности по настройке, однако дефицит дополнительных инструментов и режимов отображения существенно ограничивает программу в использовании.

[+] Выборочное сканирование
[+] Поддержка командной строки
[−] Один режим отображения файлов
[−] Отсутствие детальной статистики и отчетности

SpaceSniffer

Домашняя страница: http://www.uderzo.it/main_products/space_sniffer/index.html

SpaceSniffer — бесплатная утилита с полностью настраиваемым интерфейсом и режимом отображения данных в виде карты. На фоне аналогичных решений, примечательны такие функции, как многопоточность, поиск (в том числе сетевой), поддержка NTFS.

Для обработки можно выбрать не только диск из списка, но и каталог, указав путь в строке Path. В результате сканирования, формируется карта в виде блоков. Уровень вложенности можно регулировать с помощью кнопок Less/More Detail — соответственно, детализация уменьшается или увеличивается. Кликнув по блоку, можно ознакомиться с его содержимым, не переходя в каталог. Перемещаться вглубь по каталогам не менее удобно. Дополнительных режимов отображения в SpaceSniffer нет, однако можно настроить оформление на свое усмотрение через главные настройки (Edit — Configure).

Картинка с сайта: www.ixbt.com

Функции статистики представлены скромно. При желании, можно произвести экспорт в текстовый файл: суммарная информация, список файлов, а также файлы, сгруппированные по папкам. Что интересно, отчеты можно создавать с помощью шаблонов.

Из дополнительных возможностей следует отметить теги и фильтр. Фильтрация осуществляется по указанной маске, синтаксис описан в разделе справки Filtering help. Возможен поиск по размеру, названию папки, тегам, атрибутам и другим данным. Теги позволяют делать выборки из данных для последующей фильтрации и пакетных операций. Их можно рассматривать как временные закладки в рамках сеанса.

Резюме. SpaceSniffer не выделяется широкой функциональностью, но привлекает скоростью работы, достаточно удобным отображением данных в виде карты и дополнительными инструментами, такими как фильтр и теги.

[+] Многооконный интерфейс
[+] Интеграция с Проводником
[+] Фильтры и теги
[−] Отсутствие поиска

JDiskReport

Домашняя страница: http://www.jgoodies.com/freeware/jdiskreport/

Бесплатная кроссплатформенная утилита JdiskReport анализирует, какие файлы занимают на диске больше всего места. В дополнение, программа предоставляет статистику по распределению данных, которую можно просмотреть в виде графиков и диаграмм.

Выбирав каталог или диск для сканирования, пользователь может ознакомиться с собранной информацией или сохранить результат в виде снимка для последующего открытия. Это актуально при постоянной работе с большими объемами данных.

Статистика распределена по вкладкам: Size, Top 50, Size Dist, Modified и Types. Раздел Size показывает соотношение файлов в выбранном источнике. На выбор несколько режимов отображения: 2 вида диаграмм, график и таблица. Top 50 содержит список самых крупных, старейших и новейших файлов — потенциальных «кандидатов» на удаление. Разделы Size Dist, Modified и Types позволяют ознакомиться с распределением файлов по их размеру, дате изменения и типу соответственно.

Картинка с сайта: www.ixbt.com

С одной стороны, действительно, статистика дает почву для размышлений, с другой — в JdiskReport не продумана навигация по файлам и каталогам выборок. То есть, какие-либо файловые операции недоступны, в наличии лишь пункт «Open Explorer…» («Открыть Проводник») в контекстном меню. Отсутствует экспорт, за исключением того, что таблицу файлов и сопутствующую информацию можно скопировать в буфер обмена.

Настройки программы, преимущественно, отвечают за интерфейс. Темы оформления в избытке, а вот, скажем, для отображения столбцов или древа каталогов опций не нашлось.

Резюме. JdiskReport обходит по функциональности Scanner и WinDirStat благодаря статистике по распределению файлов. Но есть и слабые стороны — прежде всего, отсутствуют какие-либо операции с файлами и каталогами.

[+] Статистика
[−] Отсутствие экспорта
[−] Нефункциональное контекстное меню

Xinorbis

Домашняя страница: http://www.xinorbis.com/

Xinorbis — анализатор данных на жестком диске с возможностью просмотра статистики в виде таблиц, диаграмм и графиков. Программа поддерживает сканирование на различных источниках: жестких дисках, съемных носителях, по локальной сети, FireWire и др.

При выборе источника сканирования можно указывать несколько путей, включать и исключать элементы, добавлять элементы избранного. Результаты сканирования отображаются в виде сводки (Summary): эта информация поможет быстро определить самый большой файл или каталог, ознакомиться с распределением данных по типам и т. п.

Картинка с сайта: www.ixbt.com

Подробная информация собрана в разделе Folder properties секции Tasks. Данные можно просматривать в виде настраиваемых графиков, диаграмм, структурировать по типу данных или расширению файла.
