don't play with system volume information,config.msi... files
U don't want to mess up ur system, right...
U can happily play with found.*** files. They are just backups of missing files recovered when u scandisk a hard disk after a sudden shutdown or so... files in any lost clusters...
So, if u have an idea of the files lost... you can rename the file found.*** to whatever file u suppose it to be & run them... like u miss a koolbluez.fla file and u suppose them to be it, just rename the found.000 to koolbluez.fla
Then run it.. if it works, u got ur file... else try on another.. a good factor for recognition will be the size of file... small files are not worth recovering.. but those larger... like those 200+kb or in mbs... could be some *.zip, *.exe, *.doc, *.jpg... files..
Happy recovering.....
