I accidentally deleted 5 ai (Adobe illustrator images) files and used disk drill to recover them.
however, only one file was successfully recovered.
other 4 files are recovered also, but not able to open. (still has same amount of size though)
are there any other options to recover those 4?
Please SAVE MY LIFE T-T
Have you checked the article I provided the link for? It explains how data recovery works. There’s no guarantee that everything you deleted can be recovered. Trying Deep Scan is also important, Quick Scan will only locate those files that are still listed in file system. Deep Scan may get more deleted items from your disk, if they are recoverable.
You should always start with a Quick Scan, and only afterwards proceed to Deep Scan. While there’s no guarantee that everything can be recovered, Quick Scan has less chances of producing corrupted files, than Deep Scan, but may not find files that were gone long ago.
