You can customise the mail program so that all your mail files are automatically held in one directory. These files are known as folders.
To do this:
1. Create a directory to keep your mail folders in.
2. Set the value of the environment variable folder to the pathname for this directory.
To save a file to a folder in this directory, save the mail as usual, and append a + (plus sign) to the name of the file (folder) that the mail is to be stored in.
