Of course, keep in mind that using the 3-pass wiping takes 3 times as long to complete. The first pass uses the byte 0x55 (which happens to have the binary representation of 01010101), the second pass uses the byte 0xAA (or 10101010 in the binary presentation), and the third pass uses the byte 0. (This would be the case of you vs NSA/CIA/FBI kind of a situation.) To make it much more difficult to conduct such an investigation, you may want to select the 3 passes option, in which case AB Commander overwrites each byte 3 times. There are ways to analyze the physical structure of the magnetic matter of the disk plates used to store the information and recover the bits and bytes that were overwritten with 0s though. For the majority of the real world situations this would be enough to prevent someone from recovering the contents of the deleted file. If you select 1 pass, then AB Commander replaces each byte of the file content with 0.
The bytes used to wipe out the content of the files depend on the number of passes you select next to the Wipe the content option.

This way, if someone gets hold of your disk and uses an undelete program to recover the file you've deleted, the recovered file would contain the bytes written over by AB Commander when wiping the file, rather than the original content of the file.Įncrypt and password-protect external drives with USBCrypt encryption software for Windows 11,10,8. If you select this option, then before deleting the file, AB Commander wipes its content by writing constant bytes over the actual data the file contains. What if the file contains sensitive information that you want to actually be destroyed? That's what Wipe the content option is for. In any case, the important fact about deleting a file without moving it into the Recycle Bin is that the content of the file is not getting destroyed and there is a possibility to reconstruct it (or a part of it), even after the file has been deleted. If the file has been deleted only a few minutes ago and you have not created any new files yet, there is a good chance to undelete the file in this way. That is, even though the file disappears from the file listings, its content still remains on the disk! That's what makes the undelete programs possible: they work by analyzing the internal structures that Windows keeps on the disk and use that information to reconstruct the files deleted in this way. If you do not select the Move to the Recycle Bin option (or, if the file is located on a drive that does not have the Recycle Bin), then the deletion occurs differently: instead of moving the file to the Recycle Bin, Windows marks the blocks of the hard drive space occupied by the file as available for use by other files.
The same happens when you delete the file with AB Commander and select the Move to the Recycle Bin option on the Delete window. If you use Windows Explorer to delete a file on a drive that has a Recycle Bin on it, then the file is not deleted at all! Instead, Windows moves it to the Recycle Bin, giving you (or someone else who gets hold of your disk) the possibility to restore the file you've "deleted". To understand the need for this option, let's consider what happens under the hood when you delete a file. You've been probably wondering, why would you need that option? Isn't the Delete command supposed to do that by itself? If you've been using AB Commander to manage your files and folders, you've probably noticed the Wipe the content option available on the Delete window (that appears when you choose the Delete command from the menu of AB Commander): Take control of your files and folders with AB Commander file manager for Windows 11, 10, 8.
