386MAX - QCACHE
	Do not use Qcache from 386Max v6.02
	with the DoubleTools driver.  

ADDING FILES - File Director
	If you are adding files in the File Director, and you
	decide to cancel, the operation will not stop until
	the current file is finished.

AUTOMOUNT - Recommendation
	Do not unmount an automounted drive.  

AUTOMOUNTING FLOPPIES 
	When you insert a compressed disk in an 
	Automount drive, the drive does not appear 
	on the DBLSPACE drive list.  The DBLSPACE
	utility will not recognize it until you access it. 

	Immediately after you compress a disk in an
	automount drive, it is sometimes not recognized
	as compressed.  If you remove the floppy from the 
	drive and insert it again, it will be recognized.

BERNOULLI DRIVES - Automounting
	When you first bring a Bernoulli drive online,
	you must mount it by hand.  Thereafter, it
	will automount.  (See also, SYQUEST AND
	BERNOULLI DRIVES in this Readme file.)

CHKDSK vs. RESCUE - DoubleTools Driver
	When the DoubleTools driver mounts a disk with  
	MDFAT errors,  it  will mount read only.   
	CHKDSK and RTOOL can  fix these errors, but 
	you may have to run CHKDSK twice. 

		RTOOL:  If you have MDFAT errors, run 
		
		RTOOL /F once.
		
		or

		CHKDSK:  If you have only MDFAT errors, you can
		run CHKDSK /F once.  If you have both FAT and 
		MDFAT errors, run CHKDSK /F two times in a row.

COMMIT - Compression Central
	In the Drive Balancer, when you have selected a new compression
	ratio or CVF size, you click the COMMIT button to make these
	changes to your compressed disk.  

	When you click COMMIT, Compression Central closes all
	running programs, shuts down Windows, resizes your disks,
	and restarts Windows.  You must restart application 
	programs manually -  including DoubleTools.

DATA TRANSPORTER - File Director
	The Data Transporter allows you to create a compressed drive 
	and send it through a modem to a friend on a remote system.
	Your friend can then open the compressed drive, and read from
	and use programs on the compressed drive.  Your friend's 
	receiving system is not required to have DoubleSpace or
	DoubleTools.

	How to use the Data Transporter
	The sender
	1.	Create file lists
	Double click the File Director icon from your program group. 
	To create your compressed file or files, use the File Director
	to set up a list of files and a destination path. (See the
	DoubleTools User's Guide, Chapter 5.)  Select Data Transporter
	as the target drive.

	2.	Preview
	Click the preview button in the tool bar at the top of the
	File Director window.  You can select the baud rate
	for your modem.  Then click OK to proceed with the
	copy.  As you exit the preview box, you will see an
	estimated transmission time for the file transfer. 

	3.	Copy
	When you click the copy button from the tool bar, you see
	a dialog box which asks for the filename.  The default file
	extension is ADT, but you can use any name or extension. 
	Then the File Director creates a compressed file and writes it  
	to the specified directory on your hard disk.  This is the file
	you will transfer to your friend via your modem.

	When you send this file, you must also send the file
	TRANS.EXE.  This will allow the receiver to read from
	and write to the compressed file.

	The receiver
	To read from and write to the file, the receiver types:

		TRANS filename  (the filename is the
			name you gave the large compressed 
			file and if the extension is ADT, you 
			don't have to specify it). 
	This brings the data on line with a new drive letter on
	the receiver system.

	The receiver must be sure there is a statement in the
	CONFIG.SYS file, LASTDRIVE=n  (n is a drive letter).
	The drive letter must be higher than the Last Drive
	letter in the DBLSPACE.INI file.  If not, there will be
	an information box telling how to set up the file.

	When the receiver is finished reading from  the drive,
		type TRANS OFF.

	Data Transporter tips
	The sender
	You can simplify the receiving process for the receiver.
	Addstor provides a file to make transporting files easier.
	This file is ADT2EXE.  From DOS or a Windows DOS  
	session, type: 

		ADT2EXE filename

	This creates a file with the same name as the ADT file
	and EXE extension.  The file is put in the same directory
	as the ADT file.  Now you can send the EXE file to the 
	recipient.  If the file has the ADT extension, the receiver 
	does not have to specify it. 

	The receiver
	To run the file, type only the filename (without the EXE 
	extension).  The file mounts itself with a new drive letter.

	When the receiver is finished reading from and writing
	to the drive, type:

		filename OFF

	Example:  To send the compressed file Addstor.adt,

		type ADT2EXE ADDSTOR.ADT
		ADDSTOR.EXE is created

		Data transport ADDSTOR.EXE

		The receiver types,

		 ADDSTOR 

		to access the drive.  Then the receiver types, 

		ADDSTOR OFF 

		when finished reading from or writing to the drive.
	
DEFRAGMENT - Insufficient free-space errors
	The Defragment utility needs extra disk workspace
	while it is running.  Even though you seem to
	have sufficient disk space, you could see an 
	"Insufficient free-space" error.

	When you see this error message, either stop
	the defragment utility, or delete some files to 
	make more room on the disk.  This error will
	not damage your disk or any of your files.

DEFRAGMENT - Selective defrag in Compression Central 
	In this version of DoubleTools, if you are in 
	Compression Central and you select 
	the Disk Analyzer, you can see a display of
	File Fragmentation.  If you select a range of 
	squares representing fragmented files, then you
	click the defragmentation icon, you will defragment
	the entire disk rather than the selected files.

	Please send in your Media Spanning coupon for 
	an updated version with  the Selective 
	Defragmentation feature.


DELETING DOUBLESPACE CVF - WARNING
	When you want to delete a CVF file (DBLSPACE.xxx), you 
	must be sure to also delete the Activate Drive 
	line from the DBLSPACE.INI file. 

	If you fail to delete the line from INI files, your system may 
	not be able to function normally.  You can avoid this 
	problem by deleting the drive from the DBLSPACE shell. 

DISK ANALYZER ICON - Compression Central
	When you click the Disk Analyzer icon, you have a choice of 
	three displays, File Fragmentation, Isolated Sectors, and 
	Compression Map.

	In these screens, if you click the Magnify icon or the Files 
	icon without selecting any of the colored squares 
	representing files, the action applies to the entire area 
	represented in the display.

	If you click one of these icons after selecting any of the 
	squares, the action applies to the entire area 
	represented by the selected squares.

DISK FULL WARNING
	The DoubleTools driver reserves some space at the 
	end of your disk for safety reasons.  Because of this,
	it may report less free space than DoubleSpace.  
	Occasionally it will allow you to write to the disk
	even though "0 free space" is reported. 

DOUBLETOOLS DRIVER - Free Space Reporting
	When you run CHKDSK with the DoubleTools
	driver, you may see that DOS reports different 
	"total disk space and "bytes available on disk" 
	than with the DoubleSpace driver.

	It is normal to see a difference in these numbers.  
	
	This is because of a free space reserve DoubleTools
	maintains.  DOS also uses a different method of 
	estimating compressibility of new files.

DOUBLETOOLS DRIVER - Memmaker, QEMM, 386Max, etc.
	If you have run Memmaker, QEMM, 386Max, or any other memory
	management software that specifies the size of device drivers, 
	and you install the DoubleTools enhanced device driver, you 
	must run the memory manager's optimization (Optimize for
	QEMM, Maximize for 386Max, Memmaker for Memmaker) before 
	rebooting.  (See also, MEMMAKER and QEMM 7 topics in 
	this Readme file)

DR DOS - 5.0 and 6.0 with UDEON
	At this time, UDEON does not run with DR DOS (with 
	or without SuperStor).  

DTCONFIG - To configure or re-configure DoubleTools
	Dtconfig lets you choose whether to run Addstor's Double
	Tools driver or Microsoft's DoubleSpace driver. 

	If you choose to run the Addstor driver you will also be able 
	to configure other additional features it provides.

	To use Dtconfig, double-click the Dtconfig icon in the
	program group that is installed when you install DoubleTools.
	Use the online help to step you through the reconfiguration
	of the driver, Compression Central, or the File Director.

	If you change any settings in Dtconfig, the changes do not
	take effect until you reboot your system.  When you exit
	Dtconfig, it will offer to close all running programs, shut down
	Windows, and reboot the system for you if necessary.

FILE CABINET - Compression Central
	If you open File Cabinet on a disk with a large number of files,
	the files are shown on multiple screens.  If you select 
	some files, your files will become unselected after:

	You change the sort order

		or
	
	You scroll down to the next page
	

GLOSSARY - Addition to Glossary
	Create:  In DoubleSpace terminology, when you want to create a 
		compressed drive, you perform a "create" command.  
		You are then prompted for information for the 
		compressed drive such as: Drive letter, Compression 
		ratio, etc..

INI FILE - File Director & Compression Central
	Here is a summary of some of the settings of the DoubleTools
	INI file (DBLTLS.INI).  If there is an invalid value listed in 
	your INI file, DoubleTools will revert to the 
	defaults (listed below).

	Most of these values can be set from the DTCONFIG
	program.  (Click the Dtconfig icon in your program group.)

		SourceDrive=C:  This can be any fixed local drive.  
			The default drive is the File Director Startup Drive.

		TargetDrive=A:  This can be any local removable drive or 
			"Data Transporter"  The default drive is the first 
			removable drive on the system.

		Copy/Method=Sequential:  This can be Sequential or
			Optimization.  The default method is Sequential.

		CompressedTarget=ON:  This can be either ON or OFF.  The 
			default is ON if the compression driver is loaded.

		UDE=On:  This can be either ON or OFF.  The default is ON 
			if the UDE driver is in the same directory as the 
			File Director.

		CollapseDir=Off:  (Collapse Directories) This can be either 
			ON or OFF.  The default is OFF.

		RecurseSubdir=Off:  (Recurse Subdirectories) This can be 
			either ON or OFF.  The default is OFF.

INSTALL - Not on SuperStor compressed drives
	DoubleTools does not install on SuperStor 
	compressed drives at this time.

INSTALL - Games
	The following games have some special installation
	information:
	 "The 7th Guest"
	If you are running the DoubleTools drive and you are installing
	"The 7th Guest" software, you will see the message:

		Not Ready:  Abort, Retry, Fail

		Select Fail to continue your installation.

	"The Curse of Enchantia"
	Install this game only with the DoubleSpace driver.  
	The DoubleTools driver does not allow the install of
	this game at this time.

MEDIA SPANNING - Please send in your coupon
	The media spanning option in the File Director
	as documented in the DoubleTools User's Guide
	is not in this release.

MEMMAKER
	If you are running Memmaker, or any other
	memory optimizer, you must first insert the
	NOUMB switch in your ADDSTOR.INI
	file.  (See the DoubleTools User's Guide,
	Chapter 7, on the DoubleTools Driver.)

	Note that the file ADDSTOR.INI is the new 
	name for DTDRV.INI file referred to in the
	DoubleTools User's Guide.

MOUNT INFORMATION - Compression Central
	Mount information:  If you are running the Microsoft
	DoubleSpace driver and you mount a drive from
	Compression Central, you can access the drive only 
	as long as you remain in Windows.  If you exit  
	Windows, the drive will show as "invalid", and you 
	will be unable to access it. 
		
	To see the drive and to access it normally, you must
	reboot your system.

	This does not happen if you are running the DoubleTools
	driver.  Any drive you mount with the DoubleTools
	driver is always accessible to you from Windows or 
	from DOS.

OFF BUTTON - Compression Central
	The Off Button on the main menu of  Compression Central 
	causes DoubleTools to terminate all of its functions and exit.
	Online help does not yet include this definition.

PREVIEW - File Director
	Periodically, when you select only small  or 
	uncompressible files, the File Director preview 
	tells you the total size of the compressed files is 
	larger than the uncompressed files.  This is because 
	there is extra space required for overhead (entries in 
	the subdirectory and the system area in the CVF).

QEMM 7
	Due to incompatibilities between the current 
	DoubleTools driver and QEMM 7, we recommend 
	that you do not use this version of our driver with 
	QEMM 7.  We are working to resolve these issues. 

RESCUE TOOLS - Slow running tests
	When you are running Rescue Tools tests on an 
	unmounted CVF, they will take significantly 
	longer than if you are running the tests on a 
	mounted drive.  
	
SINGLE FLOPPY SYSTEMS - Compression Central
	If you have a system with a single floppy disk 
	drive, the following features will not work on 
	a compressed floppy disk:

		Space Gauge
		Disk Analyzer
		Drive Balancer
		File Cabinet  

SLOW SORT - Compression Central
	Most  SORT operations are fast and efficient.  If, 
	however, you are performing a PATH sort, you may
	experience some delays.  This particular sort is time-
	consuming, especially on large drives with many files.
	It is important to note that your system is still running.
	
SYQUEST AND BERNOULLI DRIVES
	If you start Compression Central on a system with a 
	Bernoulli or a Syquest removable drive, the Drive Select
	window will show the Syquest as a "Standard Drive"
	rather than as a removable.  (See also, BERNOULLI
	DRIVES in this Readme file.)

UDE and DATA TRANSPORTER - File Director
	Although you prepare UDE disks and Data
	Transporter files under Windows, the people you 
	give them to must start their special drivers 
	(UDEON and TRANS) under DOS. 

UDEON.COM 
	UDEON will not run on a DOS 6 system using
	DoubleSpace.

	The solution to this problem is to MOUNT the
	CVF through DoubleSpace using the 
	DBLSPACE/MOUNT command.  Do not use
	UDEON as long as you are using the diskette
	on a DoubleSpace system.

UNFORMATTED DISK - Compression Central & File Director
	Please do not attempt to perform any action on an 
	unformatted disk in Compression Central or the
	File Director.
