How to fix error error-atomic-locks-not-supported in Windows 11

Solution Steps

1. 1 First, check the file system of the drive where the error occurs. Open File Explorer (Windows key + E), right-click the drive, select 'Properties', and look at the 'File system' line. If it says FAT32 or exFAT, that's likely the culprit. NTFS is required for atomic locks.
2. 2 If the drive is not the system drive (C:), you can convert it to NTFS without losing data. Open Command Prompt as administrator (right-click Start, select 'Terminal (Admin)'). Type 'convert X: /fs:ntfs' (replace X with the drive letter) and press Enter. This command converts the file system in place, preserving your files.
3. 3 If the drive is the system drive (C:) and it's FAT32 (uncommon for Windows 11), you'll need to back up and reformat. Use the built-in Disk Management tool (Win+X, then 'Disk Management'), right-click the partition, select 'Format', choose NTFS, and follow the prompts. This will erase all data, so ensure backups are complete.
4. 4 If the error occurs on a network drive, the server may not support atomic locks. In that case, copy the files to a local NTFS drive and work from there. Alternatively, contact your network administrator to enable SMB 3.0 or higher, which supports atomic locks.
5. 5 If the error persists, it might be a registry issue. Open Registry Editor (Win+R, type 'regedit', press Enter). Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem. Look for a DWORD value named 'NtfsDisableLastAccessUpdate' — if it's set to 1, change it to 0. This enables NTFS features that may be required. Restart your PC.
