ReNamer:Failed renaming

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:

Reason	Solution
File path exceeds MAX_PATH characters	Shorten the length of file name. Or the name of the folders to reach it, but note that you'll probably need to add them to the list again.
Destination file already exists (name conflict)	There are multiple options: Rename the name in the list (Refer to Fix conflicting new names). Rename the 'other' file that is at the destination to avoid conflict Manually edit the new name of the file to avoid conflict
Source file does not exist	This can happen because: You moved or manually renamed the file outside of ReNamer. You renamed its folder first Just remove the items listed in Files pane, and then add them again (with the new path).
The file is being blocked by other program	Find the program that is currently using the file (using utilities like the Windows Task Manager or Process Explorer) and close it. (Sometimes the file is still being downloaded, in which case just wait!)
You don't have sufficient privileges to rename the file.	Get privileges by contacting the Admin (or the owner if the item is shared on a neighborhood PC). If you are the Admin, check the permissions of the folder.
Invalid destination path	You may have included invalid characters to the file name, such as: \/:*?"<>|
