When you find out the shadow copies of the deleted files were never created by your Windows OS, and Windows backups weren't set up properly, download Disk Drill
to restore your deleted files and give it a try. You can even restore files when deleted from the Recycle Bin
, as Windows works that way: deleted files are not physically removed, but just marked as deleted. You may not see them in Windows Explorer, but they may still be present on your hard drive. Until these deleted files are overwritten by other data, you have a good chance to recover them.
With powerful Quick and Deep Scans, Lost Partition Search, Catalog Rebuild and other file recovery algorithms, you are in very good hands and have all the chances to get your data back within minutes and completely free (up to 500MB).
