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:

Problem	Reason	Workaround
File path exceeds MAX_PATH characters
Destination file already exists (name conflict)
Source file does not exist	you renamed its folder first	Remove the items listed in Files pane, and add them again (with the new path).
You don't have sufficient privileges to rename the file
Invalid destination path			}
