More likely the files simply do not have the proper CREATOR/TYPE.  This happens
when Mac files are moved over from the PC because the PC file system is quite
retarded and does not understand file types.  (Most PC programs rely on the
kludge of requiring users to give files a specific three-letter extension in
order to indicate which files a program can read.)  If you set the TYPE to
"MPNT" (without the quotes) using ResEdit, you should be able to open them from
any program that reads MacPaint files.  You can set the CREATOR to "MPNT" also, 
but this isn't really critical.  If you transfer the files from the PC to the
Mac using Apple File Exchange, you have the option of setting the TYPE at the
same time, which saves you from having to use ResEdit.
