/* File managing. Important notes on this file:
About the use of dialogs in this file:
If you want to add a new dialog box (or call a routine that pops
up a dialog box), you have to provide a wrapper for background
operations (ie, background operations have to up-call to the parent
process).
For example, instead of using the message() routine, in this
file, you should use one of the stubs that call message with the
proper number of arguments (ie, message_1s, message_2s and so on).
Actually, that is a rule that should be followed by any routines
that may be called from this module.
