I would find it very beneficial if the menus could filter the results to only specific file extensions.

For example; only show:

.exe | .ps1 | .cmd | .url | lnk

In my case, this would eliminate a great deal of excess files such as .dll .chm .txt .sys .inf.

In terms of complexity, is this easy to code? If so, could anyone point me to the source file which controls this?

Thanks in advance.

Edit: To be clear, I am aware of the ability to make files hidden. However this has a detrimental effect on some apps whereby they're unable to find the files or the hidden attribute gets reset.
