Функция автономных (офлайн) файлов в Windows 10 позволяет сделать определенные сетевые папки или файлы доступными в автономном режиме, даже если ваш компьютер не подключен к корпоративной сети. В этой статье мы рассмотрим, как включить и настроить автономные файлы (Offline Files) в Windows 10/Windows Server 2016 вручную и с помощью групповых политик.
Автономные файлы доступны в экосистеме Windows довольно давно. Все что требуется от пользователя – включить Offline Files на компьютере и пометить определенные файлы или папки на сетевом ресурсе “всегда доступными в автономном режиме”. После этого Windows сохраняет указанные ресурсы в локальный кэш на диске и периодически обновляет его в фоновом режиме (раз в 2 часа — частоту синхронизации автономных файлов можно задать с помощью параметра GPO Configure Background Sync).

Включить автономные файлы в Windows 10
В Windows 10 можно включить автономное файлы через классическую Панель управления.
- Откройте Центр синхронизации (Sync Center);
- В левой панели выберите “Управление автономными файлами” (Manage Offline Files);
- Нажмите на кнопку “Включить автономные файлы” (Enable Offline Files);
- Перезагрузите компьютер.
Теперь пользователю достаточно щелкнуть правой кнопкой мыши по файлу или папке в общей сетевой папке, который нужно сделать доступным автономном и выбрать пункт меню “Всегда доступно в автономном режиме” (Always available offline).
Windows начнет копировать указанные файлов в локальных кэш автономных файлов. По умолчанию размер кэша для автономных файлов в Windows составляет от 25% от емкости диска (в зависимости от версии Windows).
Теперь, если исходный файловый сервер недоступен, скорость сетевоегоподключения до него медленнее, чем заданное пороговое значение, эти файлы будут доступны для работы в автономном режиме через Центр синхронизации.
Все изменения, внесенные в автономные файлы, будут синхронизированы с сервером в следующий раз, когда компьютер подключится к сети.
Офлайн файлы сохраняются на клиентский компьютер в каталог
C:\Windows\CSC
и не доступны напрямую через File Explorer.
Включить Offline Files для сетевой папки на Windows Server
Чтобы пользователь мог помечать некоторые файлы доступными в автономном режиме, поддержка Offline Files должна быть включена в настройках сетевой папки.
В Windows Server 2016 запустите Server Manager и для роли File and Storage Services в свойствах общей сетевой папки включите опцию “Allow caching of share”.
Можно включить ручной режим кэширования для сетевой папки с помощью PowerShell (в этом режиме пользователи могут вручную выбрать папки и файлы, которые нужно сделать доступными офлайн):
Set-SMBShare -Name Docs -CachingMode Manual
Если сетевая папка находится на компьютере с десктопной редакцией Windows, нужно в свойствах общей сетевой папки включить опцию Caching -> Only the files and programs that users specify are available offline.
Настройка автономный файлов с помощью групповых политик
Если вы хотите включить службу автономных файлов на всех компьютерах в домене Active Directory, можно распространить на них следующие параметры реестра через GPO:
- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CSC – тип DWORD Start = 1
- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CscService
– тип DWORD Start = 2 - HKLM\Software\Policies\Microsoft\Windows\NetCache – тип DWORD Enabled=1
Либо можно использовать политику Allow or Disallow use of the Offline Files feature в разделе GPO Computer Configuration -> Policies -> Administrative Templates -> Network -> Offline Files. Здесь же можно настроить другие параметры Offline Folders:
- Configure Background Sync — включить фоновую синхронизацию и настроить интервалы синхронизации;
- Limit disk space used by Offline Files / Default Cache size – ограничить размер автономных файлов на диске;
- Specify administratively assigned Offline File – список сетевых ресурсов, которые автоматически должны быть синхронизированы на компьютеры пользователей и доступны в автономном режиме (можно указать UNC пути к любым сетевым папкам или личному каталогу пользователя \\Server1\Users$\%username%).
При анализе проблем работы с автономными файлами в Windows полезно исследовать события синхронизации в журнале Windows. Включите ведение лога синхронизации OfflineFiles:
wevtutil sl Microsoft-Windows-OfflineFiles/SyncLog /e:true /q
Затем, например, можно получить список успешно синхронизированных файлов за сутки с помощью такой PowerShell команды:
Get-WinEvent -oldest -filterhashtable @{ logname = "Microsoft-Windows-OfflineFiles/SyncLog"; starttime = (get-date).adddays(-1); id = 2005 } | select-object TimeCreated, @{ name = "Path"; expression = { ([xml]$_.toxml()).Event.UserData.SyncSuccessInfo.Path } }
Для очистки кэша автономных файлов нужно изменить параметра реестра Format Database и перезагрузить компьютер:
reg add HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Csc\Parameters /v FormatDatabase /t REG_DWORD /d 1 /f
shutdown –f –r –t 0
Способ 1: «Панель управления»
Использование соответствующего апплета классической «Панели управления» является наиболее удобным и очевидным способом управления службой «Автономные файлы» в Windows 10.
- Откройте классическую «Панель управления» командой
control, использованной в диалоговом окошке «Выполнить» (Win + R). - Найдите и запустите апплет «Центр синхронизации».
- Выберите в меню слева «Управление автономными файлами».
- Нажмите в открывшемся окошке кнопку «Отключить автономные файлы» и сохраните настройки.
Способ 2: Локальные политики
На более низком уровне отключить функцию «Автономные файлы» можно в «Редакторе локальных групповых политик». Этот способ доступен в Windows 10 редакции Pro и выше. Обладателям редакции Home следует воспользоваться следующим способом статьи.
- Откройте «Редактор локальных групповых политик» при помощи команды
gpedit.mscи диалогового окна «Выполнить» (Win + R). - Перейдите в раздел «Конфигурация компьютера» → «Административные шаблоны» → «Сеть» → «Автономные файлы».
- Отыщите в правой колонке политику «Разрешить или запретить использование автономных файлов» и откройте ее настройки двойным по ней кликом.
- Активируйте радиокнопку «Отключено» и сохраните настройки.
Чтобы настройки вступили в силу, необходимо будет перезагрузить компьютер либо обновить политики командой gpupdate /force, выполненной в классической «Командной строке» либо в консоли «PowerShell».
Способ 3: «Редактор реестра»
В Windows 10 Домашней редакции для отключения службы автономных файлов можно использовать «Редактор реестра».
- Запустите «Редактор реестра», выполнив в диалоговом окошке «Выполнить» (Win + R) команду
regedit. - Разверните ветку
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\NetCache, кликните по последнему подразделу правой кнопкой мыши и выберите из меню «Создать» → «Параметр DWORD». - Дайте название созданному параметру «FormatDatabase», откройте окошко редактирования его значения двойным кликом и установите в качестве значения «1». Если параметр уже существует, ограничьтесь изменением его значения.
- Закройте «Редактор реестра» и перезагрузите компьютер.
В результате функция «Автономные файлы» будет отключена. Этот способ дублирует предыдущий вариант, делая функцию управления автономными файлами недоступной.
