When you are creating New Folder in SharePoint list through UI, SharePoint automatically trims white-space from folder names. But, if you attempt to create New Folder programatically, an Exception can occur:
<nativehr>0x8007007b</nativehr><nativestack></nativestack>
This error means: The file name, directory name, or volume label syntax is incorrect. You can simply trim white-space from folder name and the error should be gone.
Thanks for sharing, solved my problem!
