The FILER becomes very useful as soon as you discover the power of the ENTER key. Put the cursor line on a subdirectory such as _DAT, press ENTER, and you'll be in the _DAT directory. Put the cursor on .., press ENTER, and you'll be back in the root directory. Put the cursor on a file, press ENTER and you will see its contents if it is a TXT (ASCII) file.
