Winamp doesn't add all files to Media Library

[rokkyrokky]

I searched in google and couldn't find answer.

I chose one folder to monitor. All files were added except all wav's and some flac's too.

Of course, when i open some of those wav's manually with Winamp, it plays just fine.

Also, I noticed that some option does not apply to wav files. I set option to show "Add to Winamp's Media Library" in Windows Explorer menu. It shows up to mp3's, folders, flac's but not to wav's.

I can't figure it out where is the problem.

p.s. I can provide any information necessary.

p.s.s. Winamp version 5.572
