Why I ask is that "album folders" could be something an application such as "MyPhoto Collection" would open. Then again you could be trying to convey that it's just a file folder that won't open.
If it is indeed an album folder then you will need to reinstall the photo album software you used before.
I had a computer crash (thanks to Yahoo tech support). Took it to a computer store that backed up my data, wiped the computer, reloaded my data. When I go to MY PICTURES about half of my album folders won't open. I can't figure out how to get them back. Please help, if you can. I am not real tech savy, so good clear instructions to help the non-tech with a problem..
