Help! Identify a "locked" unknown file type
I know very little about computers and need someone's expertise on this:
I recently discovered some photos on my Mac that taken and uploaded originally onto a PC. The photos all contain file names of a combination of approx 20 numbers/letters. When I open the file from my "recently viewed" folder the files all say locked. There is no .jpg or .jpeg. When I sort pictures by date, the date that comes up is obviously a date much after the original photo date.
I cannot locate the files ANYWHERE in my computer except whatever is in my recently viewed folder. Thanks for any help!
