Actually, with both Windows 95 and Windows NT this will be a problem.
Depending on if the system will unlock the files once the mud is shutdown
you would have two possible ways to copy over a file.
1) Reboot and dont start the mud right off, copy the new files in, and
then start the mud.
2) If the system unlocks the files after a shutdown, then you can copy
over them normally.
Im not a programmer but this is a problem we have with some DBase apps we
have here at my company. We have to reboot to get the files to unlock and
then we can make a change / copy. Good old winblows eh? Want a tougher
challenge? Try deleting an in use DLL.. GOOD LUCK, it isnt easy.
