-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dude, you don't know what you're talking about, really. To delete a file = to mark a file "deleted". There are 2 cases:
1. just mark the file as deleted and then use the space whenever needed: - - pros: speed (you just have to write a few bytes to mark a file for deletion, on fat systems just 1 byte afaik), undeleting stuff (if you are telling me that you never needed an undelete program.. well..) - - cons: some other unwanted people might undelete stuff you don't want to have undeleted... 2. delete entire file (like overwriting the space occupied by the deleted data it with other garbage data) - - pros: fewer chance of undeletion (NOT null-chances, since with proper (expensive) equipment, somebody might still recover the data.. incredible isn't it ? that's why many programs let you choose how many times to overwrite the deleted portion ... (even hundreds of times) - - cons: SPEED !!! if the system would have to overwrite every file you delete, the writing speed would be half on deletion !! (example: to delete 1 700MB movie on my system would take 0.01 sec at most for case 1 and about 20-30 secs for case2) Linux and Windows and any system which cares about itself and its users should use the first variant by default, letting the users choose if they want that kind of security like file shredded by other programs.. At least on ext2 it is possible to undelete stuff, and maybe on the others too, but nobody really cared to design such programs... by the way, deleting a file will not put it in linux (by default at least) in "a hidden dir". The space which is marked as deleted can be used by the system at any time, and it appears as "free space" (not like windows recycle bin). If I didn't understand you correctly, please excuse me.
