BitRaser for File is a file erase or shredder utility that lets you schedule common tasks, e.g. “Internet Activities: Click this tab to erase internet traces of supported browsers.”.
A conventional hard disk, one with data stored on rotating platters, uses read/write heads that float on a cushion of air over the spinning platter(s). While the basic concept is similar to the grooves in a vinyl record, the write heads have a very slight bit of side to side play or wobble, so one *track* may be a bit to the left for example, while overwriting that *track* might be a bit to the right. In theory that portion of the track not overwritten could be read & its data retrieved. Erasing or shredding a file means overwriting that storage area on the platter(s) several times, based on the theory that by making several passes the write head will move all the way to the left, all the way to the right, and everywhere in between, completely overwriting any traces of old data.
While there are all sorts of standards – the ad copy mentions DOD for example – if you Google on disk shredding, it’s apparent not everyone is convinced erasing files is bulletproof. If you’re going to throw out an old hard drive, you can also find plenty of references online that talk about drilling several holes through the drive. And erasing or shredding is useless with SSDs or eMMC storage [eMMC is flash-based storage that’s cheaper than SSDs] – contact the manufacturer or research their docs or just Google based on the make & model of drive to find out how to remove all data, *if* it’s possible.

For every modern HDD or SSD storage, a single 1 pass overwrite of the data is enough. 2 passes recommended for USB flash drives and Memory Cards because of the increased probability of failure at first time: example you don't click "remove drive safely" and because of cashing, the drive gets removed before the overwrite happens.
You can find the NIST Guidelines for Media Sanitization from 2014 at https://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.SP.800-88r1.pdf
Overwrite means physical overwrite in all standards, not just NIST. So file-based wiping (like what this software provides) is not suitable for compliance if you have flash storages which use overprovisioning (mostly SSD drives with sizes like 120 GB instead of 128 GB). A ATA Secure Erase or other methods which supported by the drive's firmware must be used for these.

Name,
While the link included is correct, won't work [at least for me] unless copy/paste 1st into Notepad, then copy/paste into address bar of browser.
"2 passes recommended for USB flash drives and Memory Cards"
"not suitable for compliance if you have flash storages which use overprovisioning (mostly SSD drives with sizes like 120 GB instead of 128 GB). A ATA Secure Erase or other methods which supported by the drive's firmware must be used for these."
Flash memory in all its common forms -- microSD, USB sticks, eMMC & SSD hard drives etc. -- is a commodity, with some lower cost suppliers & counterfeiters doing a bit of cheating, with electronics designed or programmed to appear to be higher speed &/or capacity. That may make any sort of data clearing uncertain. It's also possible to reprogram control chips to include malware, e.g. if a USB device reports it's a keyboard or mouse, Windows will automatically run software. IMHO it's not a smart move at all to plug in a USB stick or memory card if you didn't unwrap the new packaging yourself. And if the person you might give a USB stick or memory card to is smart & throws it away, why even attempt to clear data -- just throw it out yourself if you don't want it anymore.
That said, many [most?] flash memory devices use wear leveling of some form, may swap out good storage for bad, and data clearing methods built into firmware or in software the manufacturer supplies may or may not conform to standards -- IOW may or may not work. Google to find out based on make/model of drive. RE: erasing, you clear data on a conventional hard disk by overwriting it -- if you do that more than once it's called erasing. Flash memory storage has to be cleared before it can be written to again -- that's why Trim clears storage for deleted files *before* you need to write to that storage. SO deleting a file & running Trim [Optimize in win10] has the same effect as erasing a file on a regular hard disk.
