If you need to transfer files between two computers the cheapest solution is to use interlnk.exe and intersvr.exe provided with your old dos 6.2. You can use them to transfer between DOS, Windows 95, and even Windows 98. See also:

Follow these steps

1. Get a laplink cable (Printer port to Printer port is faster) they cost about $15 and connect the two computers with that
2. Copy the interlnk.exe and intersvr.ext files to a floppy disk
3. Copy the intersvr.exe to the source computer (ie. the computer where your files are)
4. Edit the config.sys file in the source computer to add the line device=intersvr.exe (if you copy the file to a subdirectory change this line to suit)
5. Restart the computer and go to the DOS mode or Command prompt mode
6. Start the other computer also in the DOS mode or (Command prompt)
7. Run Interlnk.exe in the other computer (client)
8. You must now get the message telling that the drive letters are redirected and you can access the other hard drive from this machine
9. Use Xcopy, Xtree or any other copy program to copy the files across. As an example

   XCOPY F:\ C:\ /s /e

   will copy the files and subdirectories from drive F: to drive C:
   

10. Delete the unnecessary files and put the config.sys file back to original
