ST Xformer II File Xfer Program 1.2
-----------------------------------
by Darek Mihocka 01/02/89
This ARC file contains two files:
- FXP12.DOC - this file
- STXF_FXP.PRG - ST Xformer II File Xfer Program version 1.2
The new version of the FXP is to replace the two previous versions, 1.0 and
1.1. This new version is MUCH faster at adding files to virtual disks.
The previous versions loaded, modified, and saved the virtual disk for
EACH file being added, which was really stupid, but was done to simplify
the programming. I didn't really notice the slow speed because I had always
tested it on a hard disk. Many Xformer users complained (obviously floppy
disk users), so the program was modified to be a bit smarter.
When a virtual disk is opened (by clicking on a .SD file in the left file
selector window) it is loaded into memory and the directory is displayed.
When files are added to it from the right window, NOTHING IS SAVED TO DISK.
The virtual disk file is ONLY saved when you click on the closer box of the
left window. If you attempt to quit the program before the virtual disk was
saved, an alert box will pop up to warn you. This allows you to quickly
add MANY 8 bit files to a virtual disk.
The very annoying bug of the windows not being updated after a transfer
operation is now fixed. Both windows are updated after either a file add
or file extraction from a virtual disk.
The "GO" button is now called "Transfer".
Note that several features have been dropped. The "Sector Copy" option no
longer exists, because of the less than reliable disk reading capabilities
of the ST 5 1/4" external disk drives. I recommend using an 8-bit disk drive
and the Quick Transfer Utility instead.
Another feature that was dropped to simplify the program is the ability to
open a virtual disk in the right hand side file selector. This is really not
a hinderance at all. Simply remember to use the left window for virtual
disks.
Speaking of the Quick Transfer Utility, QTU version 1.3 is now up on the
two Xformer support BBSs in the registered user's download sections. If you
are a registered user but don't wish to call those bulletin boards, simply
mail in your Xformer disk and $1, and I will send you the disk back with
the latest Xformer software. This includes ST Xformer II version 2.31,
QTU 1.3, and of course, FXP 1.2.
Further information on both the FXP and the QTU can be found in the
ST Xformer II User's Manual (October 1, 88).
ST Xformer 2.4 will be available as an update to registered users after
February 1, 1989. Again, mail in your disk and $1, and I'll send you the
update. This is a software only update. The User's Manual will be updated
for ST Xformer 2.5 due to the significant changes that are going to be
made, and that update will be announced when Xformer 2.5 is ready.
You may be wondering why the FXP still doesn't support double density
virtual disks. I was planning to add that feature, but as it turns out,
Xformer 2.5 is going to have the ability to access both virtual disks AND
ST files from within the 130XE, so that the FXP will not really be required
any more. Rather than spend my time updating FXP to handle DD disks, and
SpartaDOS disks, and TopDOS dsks, etc. etc., I will spend the time to
complete Xformer 2.5 sooner. The QTU will also become somewhat unnecessary,
because it will be possible, for example, to copy a file directly from
a double density SpartaDOS 5 1/4" disk to a 3 1/2" ST disk by simply
typing in a COPY command in SpartaDOS.
Be on the lookout for the Xformer 2.4 announcement on Compuserve and
GEnie on Wednesday, February 1, 1989.
