Frequently Asked Questions

What causes error 0xC0000106?
This error occurs when a file or folder path exceeds the Windows MAX_PATH limit of 260 characters. It's common when copying files from cloud sync folders or deep directory structures.
How do I enable long paths in Windows 10/11?
You can enable long paths via Group Policy (Computer Configuration > Administrative Templates > System > Filesystem > Enable Win32 long paths) or Registry (set LongPathsEnabled to 1 under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem). A reboot is required.
Can I delete a file with a path too long to access?
Yes. Use Command Prompt with the prefix \\?\ before the full path. For example: del \\?\C:\Users\YourName\Desktop\...\file.txt. This bypasses the character limit.
Is error 0xC0000106 dangerous?
No, it's a software limitation. No data loss occurs, but you may be unable to access or manage specific files until the path is shortened.
Will enabling long paths affect performance?
Generally no. However, some older applications may not support long paths and could encounter errors. Enable only if needed.
