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:
|File path exceeds maximum number of characters||Shorten the name of the file or any of its parent folders so that the total characters in the entire path is within the limit. Note: Windows defines maximum number of characters using a constant MAX_PATH = 260.|
|Destination file already exists (name conflict)||There are multiple options:|
|Source file does not exist||This can happen because:
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:
|Parent path changed earlier in the list||A parent folder of the affected file has been renamed earlier in the list, which makes the path of the the affected file incorrect (out of date).
This can occur when renaming both folders and their contained files/folders at the same time. For this reason, the content must always be renamed first, before the parent, which can be achieved by sorting the list by the Folder or Path column in descending order.
