+Having duplicate files is fairly easy.
+a) Just a backup of your files, to not have accidental deleting.
+
+b) Some programs implements UNDO command (Ctrl-Z) as simply copying over the working text file
+to a backup directory.
+
+c) If you tests precompiled programs, like git annex itself, it has identical files across releases.
+
+
+For more info about duplicate files, read hear these two bugreports:
