This past week I moved an install of RedMine from one server to another, or rather I just moved the database over and checked out the SVN code again. After getting it going correctly I promptly forgot about the fact it was at a new location and just worked away on my assigned tasks. Well, as it turns out I'd completely forgotten about the uploaded files, which now wouldn't download anymore. The problem was that I forgot to verify where the attached files were stored, and it turned out to be in "files" directory, so now I have to manually copy those few files over and all will be well.
