add-mimetypes-plugin
--------------------

This run-once plug adds all the common file extensions and mimetype data to your main vbulletin 
attachments tables.

Install as a normal vb plugin and visit any of the LDM *admin* pages.

The plugin will silently add mimetype information for any missing filetypes from the following list:

asf, avi, bmp, divx, doc, flv, gif, jpe, jpeg, jpg, m3u, mid, mov, mpg, mpeg, mp3, pdf
png, pps, ppt, qt, ram, rar, ra, rm, rv, rmvb, rpm, swf, txt, wav, wma, wmv, xls, zip

You can check this by visiting LDM/admin/mimetypes

After running once, you can deactivate or uninstall the plugin as it's no longer needed.  

If you leave it installed, it will recheck the filetypes table each time 
you load an LDM admin page, and reinstate any missing entries.
