I’m using a WD My Passport external HD on Windows 7 and recently moved my files to a new computer following the instructions here (https://support.wdc.com/knowledgebase/answer.aspx?ID=12937&s=). I was previously using the WD Backup software to make my backups.
I noticed that I have many many files which start with either “!!!” or “ZZZZZ”. These are also on the external HD itself. Not just at the top level, but within each folder which contains my files.
My question: are these MY files which have been corrupted? or is it simply naming / versioning scheme cruft used by the WD Backup software that can be safely deleted?
