Folders ordered chronologically

[simoncn]

The maximum size of an attachment varies depending on the file extension of the attachment. For .jpg and .png images, it is 500 kb.

The solution proposed by simbun can be refined slightly. MinimServer implements numeric sorting, so your folder names can start with 1, 2, ... 9, 10, ... instead of 01, 02, ... 09, 10, ...
