Can you restore data from a deleted file that was previously emptied?

[QUOTE="PeterDonis, post: 6853666, member: 197831"] I'm not so sure. Applications in general don't view files as sequences of blocks, but as sequences of bytes. (There are some exceptions, such as the database engines I mentioned before; but a text editor, for example, views files the way I have described.) If the disk has 512 byte blocks, and a change is made that inserts a byte after byte 500 of the file (so bytes 501 and on are now different from what they were before), saving the file in a text editor will result in every block of the file being rewritten to disk, since every block's bytes have changed.
