If you omit append-hook, the folder will be open and +closed again each time you will add to it. If you omit close-hook (or give empty command) , the +folder will be open in the mode. If you specify append-hook though you'll be able to +append to the folder. + +Note that Mutt will only try to use hooks if the file is not in one of +the accepted formats. In particular, if the file is empty, mutt +supposes it is not compressed. This is important because it allows the +use of programs that do not have well defined extensions. Just use +"." as a regexp.

In addition, %% is replaced by +%, as in printf, and any other %anything is left as is. + +The command should not remove the original compressed file.

In this case, the folder will be open and +closed again (using open-hook and +close-hookrespectively) each time you +will add to it. + + + + +Encrypted folders + + +The compressed folders support can also be used to handle encrypted +folders.
