Trying to get ISOs to work

When I download ISO files for ePSXe, they come up as rar files. When I try to run what I downloaded, it's not there to show. I have Tekken 3 online which is an ISO file, the others I download are not. Anything I can do?

Sometimes WinRAR will associate itself with .BIN files. .BIN is a type of CD Image, but WinRAR will try to open it, and can actually open it, and view the contents of a disc. The PSX games downloaded here come in multipe types. ISO, IMG, BIN, MDF. There are also other data files included with them, CCD, CUE, MDS, SUB, etc.

If you don't already, I recommend you have your computer set to always show file extensions, it will make everything easier.
Open any folder on your computer
Go to Tools -> Folder Options
Click on the "View" tab
In the box below, there is an option called "Hide extensions for known file types".
Uncheck this box and click OK.

Now you will see the extensions and it will be easier to work with.
ePSXe supports BIN, CUE, ISO, IMG, CCD, etc. 1.7.0 adds support for MDF/MDS files.

 

But Tirith, vgmaster9 said "When I try to run what I downloaded, it's not there to show" which I assume means the emulator doesn't pick up on it, so that makes me think it really isn't in the correct format yet. But I might be wrong.
