I mistakenly deleted a very important 50gb file from my seagate 1tb hard drive, and the file was too big to go to recycle bin. How do I recover? I really need some help here. Thanks
If no data was written over it, with a good recovery software you might get it back.
It's very important you stop working with that drive and do a scan with it attached to another PC.
You have to use a recovery tool in this situation. As 50GB file is too large, maybe you will be charged. Despite of this, you can choose one or more to have a try. MiniTool power data recovery, recuva, Stellar are available.
