Well, those are the tools I'd have tried too.

First the main question: do the recovered files have a reasonable size, comparable to photos from the same source?

If so, they may just have damaged headers.

I hope you have restored to a separate storage, not recovered in place.

Thank you for the response.

The folder contains nealry 60GB.

I recovered all the file (photos) into an external harddisk.

Were those JPEG files?

If so, try:

It has helped us in a similar situation.

Yes, I will try this...

Disk Dill shows the deleted files/folders, but we need to pay money.

however, i recovered from Recuva, the problem is, it is any files are not opening.
