Is it possible to create a read only file (or change it to read only) with isp?

With many computers to monitor, its sometimes hard to keep track and make sure IT installed everything without forgetting anything. I made a lisp routine to verify if (amongst other) our standard.stb is available. If not, it grabs it the first time Cad start plugged to our network and copy it locally. Very practical for laptops. Few days ago one draftsman, without knowing how, managed to corrupt and/or modify it.

Even if the source file is read only, copying it don't make the copy read only. I made many researches without finding anything about it: Is is possible to create it read only, or is it possible to make the copy read only once copied? (via lisp or vlisp). If so, how?

Thanks,

Jef!

The easiest solution will be to use a function from DOSLib extension pacakage (freeware): DOS_ATTRIB.

Or oldschool...?

(command "shell" "attrib +R \"C:\\ACAD\\SUBDIRECTORY\\FILE.txt\"")
(command "shell" "attrib +R \"%APPDATA%\\Autodesk\\AutoCAD 2013 - English\\R19.0\\enu\\support\\acad.CUIX\"")
