Computer and Softwares Tips

Same applies for all formats supported by the mplay32.exe, including video
e.g. AVI, MPG, ASF, etc. - and CD audio as well.

So, here goes:
If you want to quickly view a supported format audio/video file, and don't want to wait until Media Player loads.
You can create a new action for these file types, called e.g. "Preview", with
"C:\Windows\System32\Mplay32.exe" /Play "%L" as application specification.

that's in Explorer under Tools/Folder Options/File Types/Advanced/New.
