[QUOTE="struppigel, post: 891813, member: 86910"] Hi again. I am awake far too early and now I do have some time before we leave for a trip ;) Thank you very much for the detailed feedback! I am sorry to hear that it didn't work as expected. Sometimes, an essential structure of the file is encrypted and in those cases file recovery software fails to repair them. Please put an[B] encrypted file [/B]and a[B] reference file [/B]of the same file type in a password protected archive. E.g. using [URL='https://www.7-zip.org/']7zip[/URL] [LIST] [*]right-click on the folder you want to send to me, click [B]7-zip[/B], click [B]add to archive[/B] [*]on the right lower part below "Encryption" enter the password "[B]novirus[/B]" (without the quotes) [*]click "Ok" and wait for it finish [/LIST] Now upload the password protected archive to a file sharing service (wetransfer.com, gofile.io, dropbox) and post the link. Reason for the password: Some Antivirus scanners detect ransomware encrypted files although they are not malicious. The password will prevent them from doing that, so that file transfer services don't reject the upload. About this point, other software will not be better either. These files are encrypted partially and the encrypted part is lost. File recovery software just uses everything that's not encrypted and tries to make a working file out of it again. That's why only part of the file is recovered. If any software recovers complete files, it takes them from somewhere else, e.g., earlier versions you deleted, or similar. JPEG files are hard to recover for file recovery software if the header is encrypted by ransomware because they need a human eye to make them look decent again. Please take a look at this video (first half is enough). Note: The tool he uses is not for free. What you can see here is: It is possible to repair your files, but it is a tedious task that's very hard to automate. I guess data recovery firms could do that but considering how long it takes to just do that for one file, it might cost quite some money. [MEDIA=youtube]X5CZRg5ZB6M[/MEDIA] [/QUOTE]
