    When you 'delete' a file with windows explorer (9x anyway), it isn't really deleted in the technical sense. What it actually does is it RENAMES the file(s) with a special character (looks like an omega) which MS-DOS cannot process or 'see'. When you remove it from the recycle bin, THEN the file is deleted. Deleted isn't the same as erased, really. Deleting files is like taking them out of the table of contents, the page is still there, but as far as the computer is concerned, the page can be overwritten freely. So after a while that page will be written over (erasing the original letters). But deleting things doesn't mean that the page is written over with nothing (erased) immediately or purposely.

    ok, i think this is how it works, anyone feel free to clarify as necessary...

    the recycle bin is similar to other folders in windows except this is where 'deleted' items go in case you want to get them back at a later stage.

    as i understand it is to do with records / references on the master file table (i think thats the right term), when you delete a file it goes to the rec bin so the mft points to the location on the hard drive where the file has gone, when you 'empty' the rec bin the mft no longer has a point to the files location so that part of the drive where the file was stored is now reclaimed as 'free / empty' space, the data in the file is sometimes recoverable with recovery tools but if data is put on the same spot as the file is it will be overwritten and difficult to recover, if at all recoverable.

    there are tools to do this, try searching on google for data recovery tools

    Post Simple concept....

    A common misconception is that the data is actually removed from the hard drive [erased] when you delete a file. Any time that a file is deleted on a hard drive, it is not erased. Instead, the tiny bit [pointer] of informated that points to the location of the file on the hard drive is erased. This pointer, along with other pointers for every folder and file on the hard drive, is saved in a section near the beginning of the hard drive is used by the operating system to compile the directory tree structure. By erasing the pointer file, the actual file becomes invisible to the OS. Eventually, the hard drive will write a new data over the area where the old file is located.

    UNIX is basically a simple operating system, but you have to be a genius to understand the simplicity. Dennis Ritchie.
