I think I need something a little less M$. Look, my whole system went down (reason: unknown) and I tried some solutions before re-install windows xp. The thing was that I forgot this encryption thing and I realized of that after it was already installing. Now, my folder seems to be 0 kb (looking at the properties), do you think data is gone? here is a list of characteristics of my system:
-40Gb HDD with 2 NTFS partitions (C: & D

where C: was winxp pro partition & in D: i kept only "My Documents" (as private folder).
Thanks a lot for reading the post KC.
