How to recover folders from a file?

Question

Data recovery

Such a situation - there is a flash drive with a half-dead file system. After recovery, the directories that were on the disk were restored as files without extensions. Judging by the weight of the resulting files, the internal contents are intact. Therefore, the question is - is it possible in any way to open these "files" in order to extract the required documents from there?

Answer 1

1/ initially it was necessary to save the failed flash drive as an image or clone and only then try to restore something yourself
2/ depends on the software used
3/ by default, flash drives are not a place for important and necessary files

Answer 2

well, you need to look at what your recovery software did
