what happens to deleted computer files?

Answer 1

they are stay on your hard drive until other programs will be write over them

Answer 2

It depends on what operating system your using, along with what file system your using.

For example, on Windows using FAT32 or NTFS, a deleted file is really just deleted from the file allocation table. To the operating system and the casual viewer, the file appears deleted.

However, the file isn't truly deleted. It is still there until the operating system overwrites the area on the disk where the file used to be. This is why some programs can recover deleted files.

To truly delete a file, it not only needs to be removed from the file allocation table, but the area on the disk where the file resides needs to be overwritten. There are programs you can get that do that as well.

windows stores file's information in FAT (file allocation table) ; other os have their own file systems which tells the os about the location and different details of file. So, when a file is deleted , whole file from the hard disk or memory is not washed off, simply FAT is deleted and the memory space when the file is actually present is not recognised and treated as free space . So, using some recovery softwares , these files can be recovered until no other file is written in the same physical location . There are many softwares to revcover the deleted data like tuneup utilities undelete.

Answer 4

All the computer files that we create or save are stored in the memory (Hard disk). The memory have address for each location. The starting location (address) of all the files which we have are all stored in a table like file called FAT (File Allocation Table).

Now when ever you open a file, the contents of that file are retrieved from the memory location using the address stored in the FAT table.

If you delete a file, the actual contents in the memory will not be deleted. Just the starting address of that file will be removed from the FAT table. So now if you are creating or saving new files, they will be overwritten on the deleted file's memory space.

Answer 5

First of all, the files go to Recycle bin. (unless u override it by pressing Shift key while deleting).
IRecycle bin is a special system folder for this purpose, and you are able to restore the files back from it.
Once the file is removed from Recycle bin, its entry is removed from FAT or NTFS, and the OS treats the space formerly occupied by the file as free space, ready to be overwritten.
Before being overwritten, however, note that the file still exists on the harddisk, and some smart software (Like Undelete from Norton) can still recover it (wholly or partially).
If you don't want this to happen, say for security reason, you can use special utilites (Like KILL from Norton or Purge from Centerpoint) to completely remove the resident data from the disk.

Answer 6

extraordinarily nicely not something, rather. Deleting in simple terms receives rid of each and every of the administration hyperlinks, the handle signals that tell the position the files is and a thanks to collect it. it rather is the undesirable information. the sturdy information is that the memory places are again to ordinary accessibility and ought to, and finally will, be overwritten with the help of new training (the recorded files is finally replaced). you may regularly get better deleted archives in the experience that they have got not yet been overwritten, and with some paintings you may regularly get better aspects of archives that were in part overwritten. This latter action is plenty harder and the majority do not have the aspects to make an useful restore record. to eliminate previous recorded information for which there is not any link (deleted stuff), you may thoroughly reformat the memory, thoroughly fill the memory with new stuff, or use some rather good application that ought to move in and reset all unused memory, it rather is extraordinarily nicely what reformatting a disc does.

Answer 7

Well i dont want to go too technical but i can tell you simpley:
basicly it goesin your recycling bin and stays there till something takes it place.
If you delete a file and empty your recycling bin, there is a way of getting it back as long as you didn't delete anything else after that or save anything to your hardrive.

Incase you were asking for a more technical question- like when we throw things in the bin, it goes to the skip and then they chemically break it down and stuff and eventually tirn it to compost which we use to grow things in (and so on....), all i have to say is gooood question! Does electronic material cycle around like it does in the real world or what??? According to laws of science it would just cycle around like the rule of conservation of energy (blaa balaablaa).

hhmm... makes you think!

Answer 8

They continue to remain on u r computer and new files are overwritten on that.. but there are softwares that can retrive files deleted even if on the same place there are more than 6 rewritten

Answer 9

Deleted is not really deleted...Windows just makes that space "writeable" again. It can now reassign any new data to be written in the same area where something else once was...so often times a data recovery program may work, if it hasnt been overwritten many times yet.

Answer 10

deleated files are moved to recycle bin.
if u delete them from recycle bin they are still present on the hard disk until they are overwritten by new data.

u can retrive the files even if they get deleted from recycle bin and are still not overwritten,using file recovery softwares (which u can search on google).
