I am looking for a simple file manager which would handle uploads and downloads.

I need something which can break files down into multiple categories and sub-subcategories. The downloads are only documents, so I dont need to add extra information/fields. I do need the information to be displayed in simple list order under their category/subcategory. (it would look like a bullet point list of downloads)

If this application was really great, it would have the option to upload multiple files at once. A great example of this tool is on the Nexo Beta.

Any info on where I can find this module, or how I could make it, or if someone else has made it for themselves. Anything would really help here. Thanks.

try mydownloads

but you need to edit the templates to make it look what you want
