The process of deleting files
October 29, 2007
Windows was the first to introduce recycle bin. The main use of this particular bin is that the deleted files and the documents will be stored in the recycle bin. This was first introduced in the version of Windows 95 OS. When an important file is deleted unknowingly then it can be restored from the recycle bin. It can be restored by double clicking the recycle bin tab and the wanted files can be restored by the options given in the screen displayed. If the file is taken out from the recycle bin then the file can be used as a normal file.
In some cases like floppy disks and some USB drives the deleted files will not be stored in the recycle bin. Sometimes you may delete an important file you wanted from the recycle bin.
Unknown Destination
While emptying the recycle bin where does the file go? It is not a mysterious thing. It is a false impression that the data is really erased from the hard drive when you erase a file. When a file is deleted on a hard drive, it is not erased. Instead, bits of information that point to the location of the file on the hard drive will be erased. This pointer, along with other pointers for each folder and file on the hard drive, is saved in a segment close to the source of the hard drive and is used by the operating system to compile the directory tree structure. By expunging the pointer file, the real file becomes imperceptible to the operating system. Ultimately, the hard drive will write new data over the area where the old file is located.
Internet has got lots of options to restore the deleted files. All the options will be easier to perform. The basic concept of deleting files in the computers follows replacing the new files with the old. Even when a file is deleted, the whole space will not be retained but some kilo bytes of space will be taken by the deleted file. When a new file is installed in the computer then the old one is erased. This is how the deleting and restoring of files in a computer takes place.
