After dragging and dropping amount of documents to the server (roughly about 6gbs) using window explore (not uploading through the SharePoint site), I’m not able to delete files, create sites, or even edit.. nothing! However, I can browse through the site like nothing happen. How can I deleted the files I recently uploaded?
When I do so, I’m receiving this message…..
I try setting the database is full and it’s not, so I’m not sure what to do?

While I tried deleting the site…

Could be one of several reasons for this. Check the following:

If you look at the error message, it mentions creation of new Wiki page… try deleting it?
