There can be several reasons for a failed renaming operation. Validation process will try to prevent some common problems prior to renaming by raising warnings during the preview process, but it cannot catch all possible problems. The most common reasons for failed renaming are as follows:

1. File path exceeds MAX_PATH characters
2. Destination file already exists
3. Source file does not exist
4. No permission to rename the file
5. Illegal destination path
