How to permanently delete a file?s?

[GarrettRocky]

so i know after you delete a file to your trash bin, its not actually gone. it still can be recovered from what i read. is there a program or something that i can use to 100% delete it and never have to worry about it being recovered? thanks for the help

When it's in the recycling bin, you empty the bin. Those files cannot be recovered, they are deleted.

EDIT: Although, restore programs like Windows restore could keep it so be mindful of that

When you delete a file, Windows just moves it to the trash bin (recycle bin). When you empty the bin, the file is deleted. But "deleted" for Windows just means the first byte is changed to a value that tells the computer "nothing to see here, move along." The rest of the file (everything except the first byte) is still on the disk.

If you use the computer long enough, the space taken up by the remnants of that file will eventually be overwritten. But until then, someone can recover part or all of the original file, even though it's been deleted and emptied from the recycle bin.

To truly delete a file, you have to overwrite all the space it's occupying on disk (*SSDs are an exception - see below). There are a bunch of tools which will let you do this on a file or folder level. For ease of use, look for a utility which adds a secure erase option to the right-click context menu.

While these tools will delete the copy of the file you see in File Explorer, they might not get everything. Many programs (like Word) create automatic temporary backups. These are deleted the simple way I first described above, so they could conceivably still be recovered. Some people suggest encrypting your file system instead of trying to secure delete everything.

* SSDs use flash memory, and flash memory cannot overwrite a 0 with a 1, or a 1 with a 0 like a HDD can. It must first erase the flash memory cell. i.e. 0 -> erased -> 1, or 1 -> erased -> 0. The erased -> x step is really fast. The x -> erased step is really slow. So the SSD will look for files which have been deleted, and erase those memory cells in the background while the drive is not busy. This is why TRIM was important - TRIM is how the OS told the SSD which files had been deleted, and their memory cells safe to erase. So even if you don't secure erase stuff on a SSD, the files will become unrecoverable much more quickly than with a HDD.

Like said above, the regular delete only moves files to the recycle bin and they can be easily recovered... and to permanently delete them, you have to delete them from the recycle bin.. but they can still be undeleted with third party software such as Recuva, and only as long as the disk space where deleted files were, has not been overwritten with other files. To permanently delete files without the possibility of recovery or undelete you need to use a File Shredder program which have diferent algorithms for shredding levels to securely and permanently destroy files and overwrite their location disk space.

I use File Shredder (No 15 in the following list) because it's fast, it adds an explorer context menu extension, and the program can be recalled so you can drag and drop filles and folders into it, to shredd them later.
