Not sure whether it would work for TurboC and the old command.com shell, but you could try creating the command using double quotes to handle filenames with spaces. Don't know what will happen for long file names though.

e.g.
copy "c:\yserver.txt" "c:\documents and settings\luffy-san\desktop\tcp1241_assignment3\lecture notes\server.txt"

Mmm
C++ Syntax (Toggle Plain Text) 
  1. $ dir
  2.  Volume in drive C has no label.
  3.  Volume Serial Number is F8A8-3449
  4.  
  5.  Directory of C:\temp
  6.  
  7. 25/09/2006  19:00    <DIR>          .
  8. 25/09/2006  19:00    <DIR>          ..
  9. 25/09/2006  18:58                 2 my long filename.txt
  10.                1 File(s)              2 bytes
  11.                2 Dir(s)  13,895,516,160 bytes free
  12.  
  13. $
  14. $ copy "my long filename.txt" test.txt
  15.         1 file(s) copied.
  16.  
  17. $ command.com
  18. Microsoft(R) Windows DOS
  19. (C)Copyright Microsoft Corp 1990-2001.
  20.  
  21. $ copy "my long filename.txt" test2.txt
  22.         1 file(s) copied.
  23.  
  24. $ exit
Maybe it's just enough if you surround the long filename with double quotes.
But bear in mind that command.com also has a limit (like 128 characters) on the length of any command line, so there could still be problems.

Nothing like getting bitten once or twice while writing a bat(cmd) script.

Yes it is.

So just using double quotes should be good.
