Please help me open old files without extensions!
I need help opening image files that no longer have extensions. I have tried on-line conversion software, but it says it's unable to find the file source. I tried adding extensions like .PCT and then putting them through the conversion software, but the file I got back was just a black square. When I click on "get info," most of them are listed as Kind: "QuickDraw picture." By the names of the files in the folder there is a tiny image of what the picture should be, but the preview image is a blank white page. I also have one file that says Kind: "Photos Document" and Version: America Online v5.0, so I am not sure how it originated but I know they are all old photos and I would love a way to open them if possible!
Thank you
