I am trying to open a dialog box where the user selects a certain folder on pure C , no .Net framework or C#, and am struggling to find how the lpstr would filter everything but directories. I am currently using the OPENFILENAME function. I tried filtering to .dir, but it does not work. Anyone know the actual extension or any solutons?

The OPENFILENAME struct is used with the old GetOpenFileName() Common Dialog Box, which can't be used to select a folder. It is simply not designed for that purpose.

You need to use SHBrowseForFolder() instead, or in Vista you can (and should) use the newer IFileOpenDialog Common Item Dialog with the FOS_PICKFOLDERS option enabled.

Ended up using SHBrowseForFolder() https://docs.microsoft.com/en-us/windows/win32/api/shlobj_core/nf-shlobj_core-shbrowseforfoldera
