 Where File Goes When Deleted Permanently?

Most of us think that when the file is deleted permanently from the Recycle Bin it will be no longer to the computer memory. But the truth is that the file remains on the computer, the only thing that deletes is the reference of that file but space will not be used by that file again, it will be free to store the new file. The computer is not able to read the file if deleted permanently as the file is technically present there but the computer can recover that file to the computer if the new file doesn’t replace the space of that deleted file. Once the new data stored in the computer the deleted file will not be recovered easily. It’s very fewer possibilities to recover that data again but it is the best way of deleting data permanently from the computer.

When you create a file on an NTFS drive, two things happen. An entry is added to the “Master File Table” (MFT), which is a huge list of all the files on the drive and where they are located physically. There also exists a large table, known as a bitmap. This table stores information about whether a certain physical location on the hard drive is being used to store data. So, when you create a file, the location at which it is stored is updated in the bitmap. When you delete a file, the exact reverse operations happen. The entry is removed from the MFT and the bitmap is updated to reflect that those locations are now empty.(permanently Deleted Files)

 Why does Computer not remove file permanently?

The single file is a combination of thousands of bytes which depends upon the size of that file and these bytes are connected to each other like a bond. While delete action performs, it is easy for the computer to remove the reference to that file instead of removing the whole of the data in a short time. The processing of the computer is much faster as it is programmed to do action faster instead of taking so much time. So, the first option of the computer is to delete the preference and after that space would be replaced by any other file.

• 40 GB PATA hard plate drive is the drive when associated with the PC; it serves like as secondary storage.

• 160 GB SDLT tape cartridge is one of the cases of disconnected stockpiling. What’s more, when utilized inside an automated tape library, it fills in as a tertiary stockpiling.

• In an extensive part of the PCs, there is a memory chain of significance: Memory that is “closer” to the CPU is regularly snappier to get to, be that as it may, it is additionally comparative; data that is secured in this kind of memory, as a rule, needs electrical vitality to keep the data.(permanently Deleted Files)

• The first hard drive estimate was close around 8 inches and later it was contracted to 0.85 inches.
• The Hard disks use magnetic recordings which are similar to the recording of magnetic tapes and the capacity of the hard drive is usually measured in gigabytes (GB).

• The primary hard drive at any point made was the 350 Disk Storage Unit, not at all like headway, it didn’t bend quite recently created, however, was a piece of an entire PC framework by IBM, it was discharged in September 1956.
• IBM’s costly; the enormity of a hard drive had an aggregate limit of just shy of 4 MB, about the extent of a solitary normal quality music track.

• In 2015 Samsung holds the record for the biggest hard drive on the planet. The 16 TB PM1633a SSD, however, 8 TB drives are significantly more typical.

• IBM’s 3.75MB hard drive was the best as at 60 years back, however now you can get more than 2 million fold the amount of capacity in the 8 Terabytes at a small part of the cost.

• Those turning platters are entirely quick, for the most part turning 5,400 or 7,200 times each moment, contingent upon the hard drive.


• Talking about sci-fi, Data, the android character in Star Trek, says in one scene that his cerebrum holds 88 PB. That is substantially less than Facebook.(permanently Deleted Files)
