Archived from groups: microsoft>public>windowsxp>general (more info?)

When a file is deleted and appears in the recycle/recovery list just how was
this file "saved"? Is the deleted physical location of the file reserved and
the bin just a pointer? Is the deleted file actually moved to another file
location used by the bin function? If yes, is the file compressed? If yes, is
the compression algortihm lossy or non-lossy?

My basic "concern" is with image files. Will a recovered image file have any
degradation in quality compared to its original, deleted file?

Thanks

Files that are deleted to the recycle bin and then restored to their
original location are not changed in any way.

To further expand on Phil's answer, when you delete a file "to the recycle
bin" the file is not physically changed in any way. The only thing that
happens is that the OS marks that file name entry as inaccessible to the
normal file handling system. The physical file data is protected from being
overwritten by other files. If you "recover" the file the name is put back
into the table so it can be addressed again.

When you delete the file from the recycle bin the file name entry and the
physical hard drive space is marked so it can be overwritten by other
filenames and data. This is a simplified explanation of what goes on in the
operating system file handling system.

What if I restore the photos and now I can't locate them? They are not
in the same area as before. How can I bring them back up from my hard
drive? Need help, thanks!

You're post is unclear. Is this a hypothetical "What if"?

If you restore them, that implies they are on the drive somewhere, though
normally when restoring from the recycle bin they are placed in the original
location from which they were deleted. Use the search function from Start |
Search, to search for them by file name.
