Version 1.93 of ST_Tools is primarily a more Falcon compatible upgrade.
The only major addition is to increase the number of levels of directories from
five to nine, including the drive.
    Version 1.92 fixes several bugs in ST Tools version 1.9.  In order to make
GEMDOS see any FAT or directory changes made by the user, I did a Force Media
Change every time the user switched disks.  Unfortunately, GEMDOS closes any
files on a disk when this happens.  If a logfile is open on a disk and the
user switches from this disk, then the next time ST Tools attempts to write to
the logfile the program aborts.  This new version keeps track of which disks
are accessed by the user and forces a media change on each disk accessed when
the user quits the program, after first closing the logfile if open.  A more
serious problem has to do with disks having more than 16000 active clusters.
If the disk optimization is performed on a disk of this type, serious problems
could occur, including the loss of files and/or directories.
    One new option was added to the disk optimization.  The user can now
request ST Tools to compress directories.  This will cause all references to
deleted files to be erased from inside directories.  If any directory clusters
are cleared by this process, they will be added to the free cluster pool.
    For those upgrading to this version from version 1.8, the new features
are as follows.  For single floppy drive systems, there will no longer be an
icon for drive B.  To change floppies within ST Tools, simply take one floppy
out of the drive, put a different floppy into the drive and press the shift key
while clicking on the icon for drive A.  This will cause the program to re-read
the directory tree.  Function List FAT entries has been changed to List/Edit FAT
entries to indicate that you can now edit the FAT entries being displayed.
This function will write to both copies of the FAT on disk.  Also the Start/Goto
selector has been added to the List/Edit FAT entries function.  This will make
it easier to navigate through disks with large FATs.  Two options have been
added to the disk optimization as well as a bug fix.  The first option is to
not delete zero length files.  In version 1.8, these were always deleted.  The
other option is to move the directories to the front of the disk.  If this
option is selected, then all directories will be moved to the front of the disk
in the order they are listed in the directory tree window.  This is thought by
some people to make disk access more efficient.  The bug fix has to do with
Volume labels.  Since these are zero length files, they were deleted by the
optimizer in version 1.8.  Now, even if the delete zero length files option is
selected, these files will NOT be deleted.  Finally, two functions were added
under the File menu.  The first is Touch file(s).  With this function you can
Touch a file, which will set the Archive bit and update the file Date/Time.
These are used by most incremental backup programs to determine if a file should
be backed up.  The other function is Undelete file(s).  If after deleting a file
you change your mind, you can use this function to undelete the file.  This will
only work if the file was contiguous and you haven't overwritten any of the
file's clusters with another file.
