I have a gateway computer, with Microsoft Vista operating System. 1GB RAM. Every time I download a file, it's fine. I download ebooks on a winzip file. Every time I unzip the ebook, it always has a "READ ME/INSTALL" for installation instructions. This file is always in a microsoft digital image file, but I can't open it because the computer doesn't recognize the file to open. Somehow, it's php related, but I don't know how to make the files compatible. It only happens when the "READ ME/INSTALL" is in microsoft digital files
