I'm facing this problem where all photos in this specific folder (over 700) are named .~lock.myfile.jpg# and .~lock.myfile.doc#.
Windows can't recognize nor open these files.
How can I rescue or "unlock" my files?

Your PC has been/was infected with malware.
Refer here, and this, and this.
Honestly I'd suggest you to reinstall Windows with a clean installation disk as it's no longer worthwhile to even attempt to remove malware from an installed operating system. If you already have a backup (100% clean) that's even better. However if you feel that you don't care if your information/passwords etc are stolen and are willing to take the risk, you can follow the steps in another superuser question here.
Remember to assume that your current Antivirus has already been infected!
After all of that is done and you are 100% sure that there are no more malware on your computer, then you may now attempt to unlock the files using Dr Web or Panda - keep in mind that if won't always succeed.
Symptoms
My computer has been infected by a virus and now files with extensions such as .exe, .doc or .pdf have been renamed as locked-nameofthefile.ext.xxxx (where xxxx are random characters) and no longer work. Finally follow the instructions to unlock the files here.
Here's another user in your situation - he solved it.
After this remember to keep a backup of all your files!
