Слишком длинный целевой путь при копировании что делать windows 10

When you try to move a file to a local folder on a Windows 11 (build 23H2) computer, you may receive the following error:

Destination Path Too Long

The file name(s) would be too long for the destination folder. You can shorten the file name and try again, or try a location that has a shorter path.

An unexpected error is keeping you from copying the file.

Maximum File Path Length Limitations on Windows

The limit of 260 characters for the full file path is a limitation of the Win32 API (and not of the NTFS file system). When you try to access a file, the Windows API always checks to see if the path is longer than the MAX_PATH limit.

Modern apps that used Unicode API to access file system, has no such a restriction and can handle files/folders whose paths exceed 256 characters (up to 32767 characters). But the max file path restriction is affected on built-in File Explorer. However, the built-in File Explorer is affected by the maximum file path limitation.

Due to max path length limitations, the administrator may encounter the following problems when managing files and folder from File Explorer and other legacy apps:

• Users can create files and folders in a shared network folder that the administrator cannot access locally;
• Errors when synchronizing roaming profiles;
• Errors in data recovery from VSS shadow copies;
• Wrong directory size displayed in folder properties;
• File loss when migrating or copying data between computers.

How to Fix the Destination Path Too Long on Windows

To work around the long paths problem in Windows, first try the following simplest and most effective methods:

1. Shorten the name of the parent folder. Rename files and folders to something shorter;

2. Enable long path support in Windows (see below). Unfortunately, this is not a universal method;
3. Use a third-party file manager that supports long paths (such as Total Commander, 7 Zip File Manager, etc.);
4. Access local folders using absolute UNC paths (for example: \\?\C:\folder1\subfolder1\toolongfilename). This allows to bypass the Win32 API’s maximum path length restrictions.

Next, we will look at several ways to workaround the long file path restriction on Windows 10 and 11.

Solution 1: Enable Win32 Long Path on Windows

You can enable long path support in Windows 10 and 11, which is disabled by default:

1. Open the Local Group Policy Editor (Win + R > gpedit.msc > OK).
2. Navigate to Computer Configuration > Administrative Templates > System > Filesystem.
3. Enable the policy Enable Win32 long paths.

You can also enable long path support directly through the registry. Open the Regedit.exe editor, got to HKLM\SYSTEM\CurrentControlSet\Control\FileSystem reg key, and set the REG_DWORD parameter LongPathsEnabled to a value of 1.

Or change this registry parameter using PowerShell:

Set-ItemProperty -Path HKLM:\SYSTEM\CurrentControlSet\Control\FileSystem -Name LongPathsEnabled -Value 1

Reboot the computer to apply the changes.

This option allows you to disable the MAX_PATH restriction for win32 and Microsoft Store applications that are compiled with the longPathAware option enabled in the manifest file. These applications can now access paths beyond the normal 260-character limit.

Unfortunately, this doesn’t affect the built-in File Explorer, which is compiled without this option. So, you still cannot use Windows File Explorer to manage files with long paths, and you should use one of the tricks described below.

Solution 2. Use 7-Zip to Perform File Operation with Long File Paths

To bypass the MAX_PATH restriction in Windows, you can use the popular 7ZIP archiver. Install 7-Zip, run the 7zFM.exe app, and paste the path to the problem folder into the address bar.

You can now perform any file operations on the files in this directory from the 7-Zip File Manager GUI. 7-Zip ignores Win32API restrictions on max path lengths.

Solution 3. Create a Symbolic Link

You can shorten the total file path length by using a symbolic link. To create a symbolic link to a folder with a long path, you can use the following command:

mklink /d c:\homelink "C:\verylongpathhere…"

Now you can perform all file operations (move, rename) on the directory to which the symbolic link is assigned (c:\homelink in our case).

Solution 4. Use the SUBST Command to Overcome the Maximum Path Length

Another option is to map the problem folder to a virtual disk (for example, Z:), using the built-in Subst command. Thus, you can also shorten the path length:

Subst Z: “C:\verylongpathhere……”

Now you can work with the data on drive Z:, where the file path doesn’t exceed the Win32 API path limit. When the job is finished, you can delete the virtual disk using the Subst with the /d option:

Subst Z: /d

Solution 5. Bypass Long File Paths by Mapping a Folder to a Drive Letter

If you simply need to copy/move a lot of folders from one place to another, you can map the folder with the long path to a drive letter.

1. Access the destination folder by its UNC path and browse the folder. Copy the folder path to the clipboard; For example, \\servername\d$\users\your_long_path…, or the NT file naming format (\\?\d:\users\longpath).
   Note. The “\\?\” prefix tells Windows to stop further parsing of the path string and send the path after the prefix directly to the file system driver. In this case, you can bypass the Windows API restrictions and exceed the MAX_PATH limits.

2. Open the File Explorer and select This PC. Click on the Map Network Drive button and select Map network drive;
3. Paste your long folder path, select a drive letter you want to assign, and hit Finish;

4. Now you can copy the files/folders to this location without the error.

Solution 6. Use Robocopy Command to Copy and Move Files

You can copy or move files, even with paths that exceed the limits, using the built-in console tool robocopy.

For example, if you cannot delete the directory due to the path length limit, you can first move data from the directory using robocopy:

ROBOCOPY c:\folder1\folder2\folder3\longpath\ c:\tmp\ /MOVE /E

After that, you can delete the source folde:

Delete c:\folder1\folder2\folder3\longpath\ /q /f

Solution 7. Overcoming Long File Path Problem in PowerShell

In PowerShell 5.1 and later, to work correctly with long paths in the Get-Item, Get-ChildItem, and Remove-Item cmdlets, you must use the LiteralPath parameter instead of the Path parameter.

For example:

Remote-Item -literalpath "\\?\C:\LongPath\VeryVeryLongPath...."
