Hi Chris - I don't fully understand your ? do you mean like inside a pdf that tracks every change made - or maybe a cookie in an index.dat? I don't understand what you are driving for. I can be dense at times Cris <cris@xxxxxxxxxxxxxxxx> wrote: I think they would be considered encrypted files - I'm not sure. Does anyone know how to open a file and get rid of the part of the file that tracks the files use? This isn't for anything illegal - I'm just curious. Or - how to see if the file is one that can track its use. thanks! cris -- To unsub or change your email settings: http://www.freelists.org/webpage/pctechtalk To access our Archives: http://groups.yahoo.com/group/PCTechTalk/messages/ http://www.freelists.org/archives/pctechtalk/ Don't assist the spammers!
