The Rename Failure Handling cleaner deals intelligently with situations arising when a file name cannot be changed, either because the new name is already being used in the file's directory, or the file is locked or invisible.
If Add Characters to End of Name is checked, duplicate file names will be dealt with by attempting to append characters to the end of a file name. This will not be successful if the file name length is already at its limit. If Change Characters at End of Name is checked, the last character/s of a file name will be changed to prevent the file name clash. If both are checked, characters will be added unless the file name length is at its limit.
In all cases, the file names is changed as little as possible, using the characters in the Characters to Use field. If a file name has been given a non-Mac extension such as .DOC or .html, the body of the name will be changed, and the extension will be unaffected.
The Invisible Files / Folders setting specifies the behaviour for invisible files or folders (i.e. those which cannot be seen in the Finder). If it is set to Leave Alone, invisible items will not be cleaned and will appear in the Report as an error. If it is set to Clean Only, invisible items are cleaned as normal. If it is set to Show and Clean, they will also be made visible so that they can be seen in the Finder.
If Unlock files to allow for renaming if necessary is checked, locked files will be unlocked temporarily to allow the name to be changed. Otherwise, locked files will be given an error entry in the report (so long as Report Cleaning is turned on in the report window).
