Thanks for that useful clarification. But can Photorec handle, not deleted , but corrupted files , and help fix these. My problem is these files haven't vanished... as in a format or lost partition . They are there but due to the issue mentioned so , can't be read aka they have gone bad.
Photorec can recover files that are not fragmented. Fragmented files are files whose content is saved kind of randomly all over your volume/partition.
If your files are fragmented it doesn't matter if they did not vanish once the associated metadata is broken. The metadata is for instance then information about the files' names and their location.
Your linux file system tried to open up a jpeg file but does not find a jpeg header at the beginning of the file.
The NTFS metadata in this case points to the wrong location.
When trying to open up any other file you will either get an error message or the file will seem to contain garbagge.
By the way, you can't convert a cat into a dog by putting a sticker labeled "dog" onto his forehead. This refers to your intentions of changing the file system type.
And if you make screenshots and save them as jpeg files and convert them into png-files afterwards does not remove the jpeg artefacts.
It is not difficult under linux to save a screenshot of a window preserving its original content. I have no idea how you managed to obfuscate every picture until now.
