Three likely scenarios of computer file erasing
There are three main ways by which files are deleted from your computer. The most common of these is when we place a file in the Windows recycle bin and then precede to empty the bin. While in the Windows recycle bin files are in a sort of limbo where they can be recovered if need be but technically are no longer part of the hard drive file structure. A second means by which files are deleted occurs when we directly delete a file using shift-delete if the file is located on our PC. If the file was located on a universal connected digital media device such as a USB flash drive the basic delete function itself will remove that file.
A third and far less common occurrence by which files are deleted is based on reformatting of a hard drive or other type of digital media such as a camera SD card or even an old floppy disk. Regardless of how files are deleted from your computer the process to undelete them is much the same. That process which allows for recovery of either a single file or entire partition recovery involves downloading a data recovery tool and using it to scan through any affected digital storage locations.
