What does the commamd TOUCH do?

What does the commamd TOUCH do? I could not find it in the help files and not in the forum either.

The command CONCORDANCE does not result in a Concordance according to standardized Archival language. I think You use the wrong word overhere.  :D

The "Touch" command acts much like the unix touch command; it changes the modification time of the selected item. The "Touch" command will change the modification time to the current time, without actually having to change the data.
