RELEASE NOTES FOR AMANUENSIS
This is a utility of the 'one dumb job' variety. It does one job,
and does it fast and with minimal hoorah.
Amanuensis is System 7 and above ONLY. Its only interface is Drag
and Drop, so you cannot use it with earlier Systems. If you
double-click on it from a System 6 machine, you will get an error
message and the software will quit gracefully.
To use Amanuensis _with_ System 7 or better, simply select the files
you want to duplicate and drag them on the program's icon or an
alias of it. New files will be created, and your original source
files will remain unaltered.
Amanuensis does this: it duplicates files, combining the Finder
functions Duplicate (CMD-D) and Option-Copy in one very fast
utility. It 'sees' files of any type, and it duplicates both the
data and resource forks. An Amanuensis duplicate is an exact copy of
the original.
If you simply Drag & Drop files on the Amanuensis icon, new files
will be created in the same folder as the original. These new files
will have the extension ".DUP" appended to their names.
If you hold down the Option key while Dragging & Dropping, you will
be prompted for a different folder/volume to duplicate the files
into. The prompt takes the form of a standard SFPutFile dialog, and
the filename prompt is meaningless; we're just navigating to the
folder you want. If you hit "Cancel", no files are copied and the
software quits gracefully. If you hit "OK" but are in fact in the
same folder as the original files, the originals will be duplicated
as above, with the extension ".DUP" appended to their names. If you
select a _different_ folder/volume, the files will be duplicated
under their original names, with no extension appended.
If you use my stuff, you end up with some real jawbreaker filenames,
e.g., "file.TQM.XP8.TQM". If you hold down the Command key as
Amanuensis launches, files will be copied into the same folder as
the original, and the name of the file will be truncated at the
first period (after a non-period). For example, "file.TQM.XP8.TQM"
would yield "file.DUP". A file called "...file.TQM.XP8.TQM" would
result in a new file callled "...file.DUP", since we only truncate
at a period after a non-period, presumably an extension. And a file
called "file" would result in "file.DUP", since there is no period
in the original filename. If you hold down both Option and Command,
the Option option will be honored (IOW, you will copy with the
original name to a selected folder).
IMPORTANT: Amanuensis presumes you know what you're doing! The whole
point of the excercise is speed, so we are skipping a lot of
overhead and error-checking. For instance, before creating a
duplicate file, Amanuensis deliberately deletes any file in the
folder already having that name. The original is safe, but any
previously made duplicate will be toasted unless it is renamed.
Likewise, we are not checking to see if the duplicate will fit on
the selected volume. This stuff is up to you. If this makes you
uneasy, by all means stick with the Finder.
BUT: This is a nice little tool. For both devlopment and publishing,
I frequently duplicate files - I take the chance with the original,
knowing that I can always fall back on the copy. And, very often,
I'll want to copy a great host of files to another folder - back-up,
storage, network transfer, sneakernet traffic, etc. The first
problem is solved with a Drag & Drop. The second with an Option-Drag
& Drop. Amanuensis is much faster than the Finder, even the Finder
hacked for bigger buffers, and the more files there are, and the
larger the files, the faster it is. Moreover, for copying to other
folders/volumes, navigating by SF has it all over opening a bunch of
Finder windows (even Finder windows with their zoomRects hacked out
(grin)).
HOWEVER: An Amanuensis duplicate differs slightly from a Finder
copy. First, the Finder keeps the orignal's creation and modified
dates, while Amanuensis uses the current time and date. I can't
believe this would ever be a problem. Second, Amanuensis duplicates
the _original_ of an alais, where the Finder duplicates the alias
itself. This might be an issue, but, of course, you wouldn't gain
much from Amanuensis copying a 2K file, in any case. And third,
Amanuensis won't duplicate a folder and all its files, the way the
Finder will. It doesn't see folders at all, nor volumes, only files.
