In Unix, the sync command flushes buffered information to disk, useful if you are about to eject an external drive or if important information must be written to disk and the computer may be put in a state where it could crash.

If you need a substitute for the sync command in Windows XP, you can download it from the Sysinternals site, part of Microsoft TechNet.

Simply download the zip file Sync.zip, unzip the contained executable to your main Windows directory, and you can flush information to disk with the following command:

sync

If you only wish to flush certain drive letters, add those letters after the command, i.e.:

sync h:

Other options:

-r

This flushes removable media.

-e

This ejects removable media.
