After checking out the most common formats, I took Free Opener through its paces and opened the following files successfully: CSS (no syntax highlighting), HTML, JS (with syntax highlighting), MOV, PPT, PPTX, RAR, REG, SWF, XML, XPS, and ZIP. While I didn't try all 80+ supported formats, everything I tried worked, and I found nothing that was supported in name only.
Free Opener delivered on its promises every time. Free Opener feels like an honest try to make our lives easier, and it truly does open a large number of formats. If you need to view multiple formats and can only install one program, Free Opener can be a lifesaver. It may not be a complete substitute for other programs, but for viewing purposes, it can definitely save you some money.
Note: The Download button on the Product Information page takes you to the vendor's site, where you can download the latest version of the software. Free Opener comes with no less than four additional programs in its third-party InstallIQ installer. You can skip all these offers with one click, or review each one and choose to accept or decline.
