Getting Rev to utilize Volume Shadow Services

[Chipp Walters]

If all you're trying to do is unlock a file, this should work for you:
(WinXP)

answer file "Chose file to unlock."
if it is empty or the result is "cancel" then exit to top
put it into tfile
replace "/" with "\" in tfile
put "attrib"&& quote & tfile & quote && "-R" into DosCommand
set the hideConsoleWindows to true
get shell (DosCommand)
answer information tfile & cr & "Unlocked"
