I had a couple of mov files that I had recovered frm my SD card after deleting but after I recovered them they were playing pr

"playing pr"?

Part of your post seems to have been cut off.

Anyway, if they are recovered /previously deleted .mov files perhaps they were not fully recovered.

What specific errors or pop-up windows do you see when the .mov files "can't open"?

Need more information: e.g., OS, video player, the utility you used to undelete the files. Thanks.
