How to copy files and set Uncompressed flag ?

Hy.

I've got a litle problem, i'm using TrueCrypt to create a virtual drive that contains all the programs.
In order to have a longer lifespan of my already old USB pen, i've made a script that copies the virtual image to %temp% on the local computer, mounts it and starts PStart from that. When i close PStart, all info is saved, the image is unmounted and the image is copied back on the USB pen. (this way, the USB is accessed only 2 times/session, not a few hundred/thousands times when some programs write data to disk).

Now for the question.
For some reason, TrueCrypt (and a few other programs) don't like having the virtual image as "compressed" (you know, the "Compress" flag for NTFS files), so is there a way (a program, script or command) that can copy a file and uncheck that flag ? (so the file remains uncompressed, even if the %temp% folder is compressed). I can make that manually, but it's a pain in the ass to do that each and every time. I can also set the "%temp%" folder to be uncompressed on the computer i'm working on, but just in case i go to another computer, the "%temp%" folder might still be compressed.

Another question, is there a script command, or little application (that can be called from a script) that can copy a file and show me the progress ? for now i'm using the "copy" command, and since copying the virtual image takes a few minutes i'd like to see just how much time does it need to finidh copying.

Thanx in advance.
