A file is stored in separate clusters of space on your hard drive. As such, the file still lives - unless and until you start storing new files that end up overwriting the deleted one. Rather, the file's locations are marked as available by the file-allocation table. When you permanently delete a file in Windows, it's not physically removed from the disk. In other cases, you may decide to empty your bin to free up disk space. Even if you use the Recycle Bin, at some point it will get too full and start kicking out older files. You can bypass the bin by turning it off through its Properties window or holding down the Shift key when you delete a file. When you delete a file in Windows, that file first bounces to the Recycle Bin. If you want to revive a deleted file, an old adage applies: the sooner the better. After the clock has run out, those deleted files are purged and removed from their file servers. These services typically grant you up to 30 days to recover a file. Popular services such as OneDrive, iCloud, Google Drive, Box and Dropbox all give you ways to resuscitate deleted files, but even here you need to act quickly. If the deleted file is one you've synced or stored in the cloud, you can typically undelete it as long as your cloud provider offers some type of recycle bin or trash folder. You can scan external media, such as USB drives and SD cards, as well as your computer's internal disk. With these programs, you can run a quick search for recently deleted files and conduct a more time-consuming but thorough scan to dig up older ones. I've used and recommend three such applications: Recuva, EaseUS Data Recovery and Active Uneraser. And to accomplish that feat, you'll want to turn to a recovery program to help you undelete it. As long as you act quickly, you can usually bring that file back to life. You need a document, photo or other file that you're sure was deleted.
