Those of us who back up our devices sometimes get a message that some file couldn’t be backed up because its name — more likely its file path name — is too long. Lim Electronics‘ website offers a free, small, easy-to-use program called, appropriately enough, FindLongNames, that lets you check your Windows machine for files whose name or pathname is longer than some number of characters you specify, so you can do some adjustment beforehand and hopefully not have to deal with the long-name problem after your backing up procedure has run. Their page of free software includes other programs you may want to check out.
