In the ol' days of DOS, using the 8.3 naming convention (8 characters for the
filename, 3 characters for the filename extension to identify the type of
data stored in the file), deleting the file would result in the last
character of the filename being replaced.
If you knew the full filename, no problem. If you had deleted say, all of
the files used by an application, then changed your mind, you would have to
know or be able to figure out what the missing letter should have been.
I don't know if the process is still the same for long filenames under
Windows XP.

is this true, I believe it is and if so, can someone explain if windows xp
does the same thing.
