|here's just a general idea:|
first, run a "dir /s" out to a textfile: dir /s>PRE_DIR
obviously, this is NOT stored only on your hard drive that you lend, but local drive.
When you get the drive back, run another "dir /s" to textfile POST_DIR
then FC or otherwise run comparison of the listings, to get discrepancies. This step
WILL require some finesse, to figure out and weed out what will surely obfuscate the true data that you want to cook out/refine. Possibly just certain directories. With swap-files etc., everytime windows burps, farts or blinks, new file-system data is generated or altered. So concentrate on what you need to concentrate on. I had an idea, "snapshot", that would do this job: take snapshot of entire system (including registry content) then a complex program to filter and compare. Way over my head! Maybe there are utilities out there to handle this, but short of that, just concentrate on the files that "really matter" (your definition, not mine!)
