scandisk errors

If you uncheck the automatic fix scandisk errors, a prompt pops up and three
options are allowed. The choices are ignore, move and repair and delete the
file. If I chose the [move and repair] option, the program moves the file to
the top of the host local drive C: . My question(s) are what is repaired and
how do I restore the file to its proper folder location? Do I have to repair
this file myself? When and why would I want to delete the file?

The only errors that scandisk reports are MS-Dos name length errors that
exceed 66 characters in length. Why does win98 name some MS-Dos files like
this? Is this the only error that scandisk reports? It seems easier to just
leave the program to autofix everything it finds, but then I would never
learn what all it fixes.
