Alt key commands execute additional XTREE commands. Press the
Alt key to display the ALT DIR COMMANDS or ALT FILE COMMANDS.
These commands appear on the line where the DIR COMMANDS or
FILE COMMANDS normally appear. To execute an Alt key command,
hold down the Alt key and press the highlighted letter of the
command name.
Function keys control XTREE itself. Press F1 to quit XTREE, F2 to
display a screen of help information, or F3 to cancel a command.
XTREE displays the available commands and the key that executes
each command on the lower right of your screen.
Cautions
With a utility as powerful and as fast as XTREE, you must always be
aware of the danger of accidentally erasing important files. Follow
these guidelines to protect your files:
l
You can cancel commands, even commands in progress, by
pressing
F3. This stops any function.
l
Use Ctrl A (the attributes command) to give read-only status to
all the files in the directories. Then, in order to erase a file, you
must first remove its protection. (See your MS-DOS Reference
Manual for details.)
l
XTREE is limited in the number of files and directories it can
handle. If you have more than 2800 files or 180 directories,
XTREE displays an error message. If you see this error message,
exit XTREE and store your infrequently used files on diskettes, or
reorganize and delete some directories. If you use XTREE when
you have more files or directories than it can handle, you may
accidentally erase or alter files.
