Basically what the title says. I was kind of expecting folders to be transferable, since .zip and .rar are, but the uncompressed folder is NOT transferable across "attachments"
Kinda funny IMO.
Well, I mean they are transferable, you just get a "cannot connect" error when you do hit "post"
It is not a restriction we impose, but is built into the SMF software, as far as I am aware.
A folder is a container with multiple entities within it. Potentially some of those entities may not be permitted for uploads. .zip and .rar are single files that are compressed and while in the compressed state, it need not matter what entities are contained within, since it first has to be downloaded and uncompressed.
