This file can not be opened because it is corrupted or damaged
I was using PDF file in my ipad pro, but my device automatically went off suddenly because of the battery ran off. Afterthat, when i restart my ipad pro, and try to open the same file via PDF, it look like the file has been corrupted. The massage said 'This file can not be opened because it is corrupted or damaged'
What should i do to fix this problem?
