You can often successfully recover deleted files from a PC, phone or camera memory card or USB Memory stick, it just depends on what鈥檚 happened since the files were deleted.





When you delete files the data itself isn鈥檛 deleted, just the index entry that says where the data for those files is located. The space containing the deleted files is also now marked as free space so it is available to the system for any new files to be written there instead.





If and when that happens, then it becomes too late to recover your deleted files so it is very, very important to not save any new files or data to the device concerned.





If the deleted files are on a memory card or USB memory stick, just don鈥檛 save any new files to it.





One of the easiest ways to see if you can recover deleted files is to try some file recovery software. There are many such products available, both commercial and free 鈥?also of varying quality!





A good tip is to try the free trial version of a good commercial product that will scan the device for deleted files and show you exactly what files can be recovered as thumbnail images in the preview screen. At least that will show you if you can recover the deleted files at all or if it鈥檚 too late already.

Like they said, you have to use some recovery software to get data back. But there may be some files you can't recover. That's normal.





You can use backup software that can remind you to make backup when you want to restore. You can try this.

If the recovery reformatted the computer while reinstalling Windows you're out of luck. If you don't see your data when going to My Computer and browsing your hard drives it's gone. There are drive recovery companies but that costs hundreds to thousands of dollars so...It's gone.
You still can try to recover your data with Easy Drive Data Recovery software:

It uses unique modern algorithms to recover files that other software either recovers incorrectly or is unable to detect.
Look on google for recovery applications.
