I realize that the MB limit is placed in the config settings of wordpress and can be increased there, but I'd rather just create an additional directory on the host where files are uploaded. I'd still like to upload function to be available within the Wordpress Admin pages, but the upload to go to the created folder. Particularly, I'd like to add a box on the Post Edit screen to add the upload. This is primarily for uploading the MP3 of a podcast for instance.
I know I'll need to build a custom function to make this happen and point to the correct directory, but wanted to be sure it was possible first.
Is that even possible?
