Searching for Windows Explorer like UI component

Hallo,

atm we're searching for a UI component for browsing files and folders. Since now we have used the File Browser at http://开发者_开发知识库www.codeproject.com/KB/miscctrl/FileBrowser.aspx, but because we're facing many problems (access violations and other exceptions) we need a more stable one.

Do you know any with the following features:

• Stable!
• It would be nice if it is widely used and well-proven.
• Must be able to programmatically filter the files by extension.
• Preferably open source or for free, but it doesn't absolutely need to.

Thanks in advance,

Steven

What about this FileView Control?
