I want to upload Microsoft Excel, Powerpoint, and Visio files. Right now, the upload function only accepts Word files (from Microsoft, at least -- it accepts a host of other files).

Right now, in the uploadconfig.php file stored in the wfsection/cache directory, it has a line in the $WfsAllowedMinetype array that looks like this:

"application/vnd.ms-excel",

But when I try to upload a .xls file, it fails. Any suggestions to fix this? And any suggestions on how to allow .ppt and .vsd files?

Thanks in advance!

Oh, and one other thing. Any suggestions on an easy way to make it all case-insensitive for the extensions? Right now it allows extensions like .doc but not .DOC
