Erased DOS directory

I erased the content of the DOS directory in a old computer operating in DOS 5.0. I want to install DOS again without reformating the hardrive. Therefore, I copied the three DOS 5.0 disk back to the DOS directory. I know that I need to expand those files and I see a file called "EXPAND.EXE", but I don't know how to do it. Can you help before my boss finds out?
Thanks in advance.

Hi,

It's very simple. All compressed files have underscore symbols at the 3d place of file name extention. For example, smartdrv.ex_ is compressed smartdrv.exe file. You can easily guess the last letter. To expand such file use the command

EXPAND SMARTDRV.EX_ SMARTDRV.EXE

Repeat this for all compressed files. (Expand not delete original compressed files, so you need to do this manualy.)

Good luck, Igor M

Thanks for the input Igor. Since there are a lot of compressed files, I'm planning to install dos 5.0 in another computer and then copy all the already expanded files to the DOS directory to the machine with the problem.
