Mail Folders

elm folders are stored within the directory defined by the F)older directory field in the option menu (or the maildir variable in mailrc). The default is $HOME/Mail.

The folder may be referred to as

+folder_name
or
=folder_name

where the plus or equal (+/=) sign means that the file is residing (or is to be residing) in the folder directory. If the plus (+) or equal (=) sign is not used, the folder will reside in the directory from which elm was invoked.
