What Is ERROR_FILE_LEVEL_TRIM_NOT_SUPPORTED?
Notification about a non-supporting file system is an ERROR_FILE_LEVEL_TRIM_NOT_SUPPORTED. It is required for communicating to storage devices certain ranges of data in files that are unused, which enhances performance and optimization. Most of the time, this occurs when the files are compressed, encrypted, or a storage device uses a file system like FAT32 that does not support trimming.
Steps to Fix ERROR_FILE_LEVEL_TRIM_NOT_SUPPORTED
1. Check File System Compatibility
First, to solve this problem, you should identify the drive’s file system:
- Press Win + E to launch File Explorer.
- Right-click on the drive and select Properties.
- In the General tab, confirm that the File system is either NTFS or ReFS. If it’s FAT32, you will need to format the drive or partition to NTFS or ReFS to utilize the trim operation.
2. Disable Compression and Encryption
Then you must disable any compression or encryption applied to the file:
- Right-click the file you wish to modify and select Properties.
- Click on the Advanced button.
- Ensure both the Compress contents to save disk space and Encrypt contents to secure data options are unchecked.
- Click OK to apply changes. Disabling these features will help in preventing the ERROR_FILE_LEVEL_TRIM_NOT_SUPPORTED message.
