Hi to all.
To help the suggested tool ThisIsMyFile to do it's best I would carry out, before using it, a Scandisk just to get rid of issues on the disk. Here is a
LINK for information. I would also say that it may not be necessary to preform the "Scan and Recovery bad sectors" (doesn't hurt though (takes time) if you don't have a SSD disk). In certain circumstances a Scandisk is all you need to unlock files with issues (won't be enough here, it needs the tool).
