When a file is opened then the last access timestamp for the file is updated. This timestamp can be useful for applications that detects, whether certain files have been used recently. If not using such applications, then one might consider disabling the updating of this timestamp, to make file operations quicker.

To disable the updating of the file access time add this line in your CONFIG.SYS

ACCDATE = C- D- E- F- G-

If you don't have that many drives just remove the drive letters, or add them if the other way. Drive letter A: is disabled by default.

You can find this tip in your CONFIG.TXT in the WINDOWS directory MS Info
