Apologies if this is the wrong forum. I have a number of folders in which there are various files - mainly Word and Excel but the are a small number of Project files. In all, I'm talking about approx 800 files. Is there a utility that I could use that will batch change all these files to be Read Only with a password that can change them back to being editable - as you can do in Word with a single file? I have tried a few small apps off the net, they appear to change the file attribute to r but you can still open the doc and edit it.
