Revo Uninstaller’s Unrecoverable Delete wipes the data using advanced patterns, which takes more time than simple deletion, but renders the data impossible to recover, even if you try to do that with the most expensive software on the market.

However, since there are no guarantees how much of the old data would be overwritten, and when and, also since “most” isn’t the same as “all”, that means that some users actually do need means of erasing files securely, like important files, be they personal or business, falling into the wrong hands can cause anything from an annoyance to embarrassment, to severe financial distress, to catastrophes.įortunately, there are numerous tools that can help you wipe your data so that it can no longer be recovered. For the vast majority, this works out just because few people have sensitive data that needs to be deleted securely, and the contents of already deleted files will be overwritten sooner or later, during regular computer usage. Only removing the entry in the Master File Table, without fully wiping the actual contents of the file, results in much faster deletion. To the operating system, the region on the volume where the actual file is located now appears empty, so from that point on the operating system can use that region to store data for other files, overwriting any existing data that had belonged to the deleted file. When you delete a file, what actually happens is that the aforementioned entry in the Master File Table gets erased, but the actual data, the contents of the file itself, is left completely intact.
Whenever a file is created on the volume, an entry is written to the Master File Table with various information about the said file, including what region on the file system it occupies. It acts as a database for all files and folders on that particular volume.

You might already know that when you delete a file to the Recycle Bin, it isn’t actually deleted, it’s simply moved to a different, system folder that we know as the “Recycle Bin”, which can be emptied whenever necessary.
