.All file changed in Mac G4

Got a serious problem. Put the zip disk in from the MPC2k XL into the G4 to copy file to cd for backup. when i placed the zip disk back in 2kXL and tried to reload the .all file now has (originalname y7.all). Even the back up cd has this name on the file. Any takers as to how this happened or how i can resolve this.

Please help.
