Version 1.5
-----------
IMPORTANT NOTE FOR PREVIOUS USERS OF DA: In prior versions DA designated
the /A command line option to 'delete [A]ll files'. As of version 1.5 DA
now uses this option for 'delete by [A]ttribute'. The functionality of the
previous /A option has been rewritten and applied to the option /E, short
for 'delete [E]verything'.
Added the ability to delete files by attribute; archive, system, read only,
and hidden (or even files that have no attributes set). This was assigned
to the /A command line option.
Changed the /A (delete [A]ll files) option to /E (delete [E]verything)
because of a conflict with the above mentioned new function.
Added two additional shortcuts to the file name completion feature.
Previously, entering a filespec of . (single period) would cause DA to
expand that entry into it's *.* equivalent, similar to most DOS commands.
In addition to this feature you can now enter a file spec without an
extension or an extension without a file spec. For example; if you wanted
to delete all the files in your C:\Backup directory that began with the
letters 'no' you could type 'da c:\backup\no*' (or 'da c:\backup\no*.') and
DA would expand that into 'c:\backup\no*.*'. If you wanted to delete all
the backup files in your C:\Temp directory you could type 'da c:\temp\.bak'
and DA would expand that into 'c:\temp\*.bak'. Now, that may seem like an
insignificant change but anything that allows you to keep your hands in the
correct position on the keyboard, over the alpha keys, is always a benefit
(well, at least it is to me). Be careful though, minor typing mistakes now
have the potential to be quite disastrous (see the section titled PROGRAM
USAGE in the Da.Doc file for more information).
Fixed a bug that wouldn't allow the [A]ll option to be specified from the
delete directory confirm prompt.
Fixed a bug that would cause DA to attempt to delete the current directory
if you specified the -d option and you had selected files from the current
directory. DA's behavior should be that it only deletes the directories
you've specified when using -d and not the current one, regardless of
whether or not you happen to have selected files from your current
directory.
And finally, I fixed a long standing bug that would cause DA to sometimes
mistakenly identify a drives volume label as a file. Naturally, since it
really wasn't a file DA would bomb out if you tried to delete it. This only
seemed to occur with certain systems and when you were deleting files in
the root directory.

Version 1.4
-----------
Fixed another minor display anomaly which caused certain prompts to over
write other information already on the screen. For some reason, and only
under certain conditions, DA would stop advancing the cursor down the
screen. This behavior caused some of the displayed information to be
overwritten by something else. I've been chasing this one for the past
year, more or less. I hope I've got it this time.
Added the ability to interrupt long or erroneously executed deletions by
hitting any key on the keyboard. This was written in because of something
stupid that I did; I started to erase some files from the wrong sub-dir and
didn't realize it until after DA had started working. In order to stop it I
had to reboot. This option should take care of that. The only caveat to
this is if you get somebody who likes to 'type ahead' of a program, me
included, you could inadvertently stop DA from doing it's job.
Enhanced DA's typical Y/N/Q (Yes/No/Quit) prompt with a new option: A (for
All). Now, when questioned the prompt will be Y/N/Q/A. Selecting A will
cause DA to continue along for *all* of the remaining files that match your
specification(s). I found this to be quite useful if I wanted to use a
filespec but I wasn't quite sure if it was going to be what I thought. In a
case like that I'd always use the /C ([C]onfirm deletions) option. Well, if
there were a lot of files that matched my filespec(s) I was stuck hitting
the Y key over and over again. By adding the [A]ll option you can now just
do the equivalent of turning off the /C option.
Improved the clarity and readability of some of the error messages to try
and detail their meaning better.
-----------
Version 1.3
-----------
Fixed a bug which caused DA to ignore the /C [C]onfirm option for
sub-directories, but not for files. Sounds strange I know, especially
considering the fact that they were supposed to be using the identical
code. Sigh...
Speeded up file deletions approximately 25% by removing some redundant
code. DA is really quite fast now, especially on drives that have a disk
cache running.
I also fixed two different display bugs:
- when you selected [Q]uit from the [C]onfirm message screen
- one which caused certain prompts to over write other information
already on the screen
