It was particularly designed to be used under DESQview, although it can be used outside of DESQview as well. When DESQview is detected, DVCopy will use sophisticated techniques to be both efficient and safe. Note that it can also be used under local networks, which, like DESQview, require file sharing routines. DVCopy is capable of using a floppy drive without causing the other tasks to almost-freeze. The copy speed will be affected, of course. The priority DVCopy gives to DESQview is configurable as "Floppy Protection Level", and is discussed later. NOTE: The {+} mark specifies the feature will work for registered users only. - 3 - DVCopy 1.01 DESQview Aware Copy Utility (c) 1991-92, YossiWare ┌─────┬──────────────────────────────────────────────────────────┐ │ 3.0 │░░░ SETTING UP ░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░│ └─────┴──────────────────────────────────────────────────────────┘ DVCopy comes with a generic SETUP utility (DSETUP.EXE). Using the setup you will be able to have default configuration options built-in into DVCOPY.EXE, you will be able to print the registration form, and then, when time comes, install your key. SETUP is also capable of verifying that your DVCOPY.EXE is indeed original, and contains no patches or changes in its code. When running DSETUP, it will need to locate DVCOPY.EXE. In order to help it locate DVCopy, put DVCOPY.EXE in your current directory, or in any of your PATH directories. Once DSETUP was loaded, it will display a menu. Use the cursor keys to move the highlighter, and [ENTER] to choose. You may also use your mouse, if a you have one, and a mouse-driver is loaded. The menu options are: - Sharing Under DESQview. This will toggle whether or not DVCopy will, on default, attempt to share files when DESQview is detected. DVCopy will avoid any sharing if SHARE is not loaded. - Sharing outside DESQview. This will toggle whether or not DVCopy will, on default, attempt to share files when DESQview is not detected. DVCopy will avoid any sharing if SHARE is not loaded. Usually, this is not needed, but if you run a Local Network (LAN), you might find it very handy. - Floppy Protection Level. This will cycle the protection level which DVCopy will use, when using floppies. Note that the DVCOPY environment variable will override this default, if found. Floppies Protection is discussed later on. - 4 - DVCopy 1.01 DESQview Aware Copy Utility (c) 1991-92, YossiWare - 4DOS/NDOS Description. {+} This will toggle the support for 4DOS (and NDOS's) file-descriptions. If enabled, and 4DOS/NDOS is loaded when using DVCopy, DVCopy will copy the description of files, together with the files themselves, just like 4DOS/NDOS would of done. THIS FEATURE WILL WORK FOR REGISTERED USERS ONLY ! - Progress Indicator {+} This will toggle the use of progress indicator. If enabled, DVCopy will display the progress of copying, in precent, on the right of the screen. THIS FEATURE WILL WORK FOR REGISTERED USERS ONLY ! - Integrity Check DVCOPY.EXE. This option will check the integrity of DVCOPY.EXE, and will report if it has been changed. If it reports DVCOPY has been changed, you might want to get another unmodified copy, as this one is probably patched, corrupted or even virus-infected. - Print Registration Form. This option will print the registration form to printer (PRN). Use it when you want to register DVCopy. Information about registering DVCOPY can be found in DVCOPY.REG. - Install Registration Key. Use this option after you register DVCopy, once you get your personal registration key from us. You will be requested to type in the key you have received. Once the key is installed, you DVCopy will be registered. Note that there are no extra features in a registered DVCopy, and no crippled features in a non-registered DVCopy. - Clone Changes (Save). Choose this option after you have changed anything in DVCopy's config, and you want to burn it into DVCOPY.EXE. This is required after changing the 3 first options, or after installing a registration key, if you want to keep the changes. - 5 - DVCopy 1.01 DESQview Aware Copy Utility (c) 1991-92, YossiWare - Return to DOS. Will return you to DOS. - 6 - DVCopy 1.01 DESQview Aware Copy Utility (c) 1991-92, YossiWare ┌─────┬──────────────────────────────────────────────────────────┐ │ 3.1 │░░░ USING DVCOPY ░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░│ └─────┴──────────────────────────────────────────────────────────┘ DVCopy is very simple to use. Running it with no command-line parameters will cause it to display how to use it. Generally, the command line format is same as MS-DOS's (or 4DOS's) built-in COPY. There are 3 ways to use it: A) DVCOPY.EXE [Original File Specs] [Destination Drive/Dir] DVCopy will copy files from [Original File Specs] to the [Destination Drive/Dir] directory/drive. DVCopy allows Wildcards to be used. B) DVCOPY.EXE [Original File Specs] DVCopy will copy files from [Original File Specs] to the current drive/directory. DVCopy allows Wildcards to be used. C) DVCOPY.EXE [Original File Specs] [Destination File Specs] Examples: DVCOPY A:. Copy all files from current directory of drive A to current drive/directory. DVCOPY D:\TASM\*.ASM A:\ Copy *.ASM from D:\TASM to drive A's root. DVCOPY \UTILS\ARCS\. Copy all files from directory \UTILS\ARCS\ to current directory. DVCOPY \FD\INBOUND\0*.* \FD\BACKUP\PACKET.* Copy all files from directory \FD\INBOUND\, which begin with 0, to directory \FD\BACKUP, using file-name PACKET, keeping the original extension. There are more complicated forms for wildcarding, and DVCopy supports them all - just like MS-DOS does. Note that DVCopy does NOT support 4DOS's extended wildcarding ... Yet. - 7 - DVCopy 1.01 DESQview Aware Copy Utility (c) 1991-92, YossiWare DVCopy can also recognize switches that are passed through the command-line, and are used to override the default setup, and/or to toggle on (or off) other features. All switches are not case sensitive, and can be placed ANYWHERE on the command line. DVCopy recognizes and support the following switches: - Move files, instead of plain copy - [/M] {+} The /M switch is used to instruct DVCopy to move files. When files are moved on the same drive, DVCopy will use a "fast move" option, and won't have to actually read and write the files. When files are moved between drives, DVCopy will copy each file, and once the copying is complete, it will erase the original file. Note that if you have 4DOS/NDOS Descriptions support enabled, DVCopy will also move the description of the file with the file itself, just like 4DOS would have done. Examples: Move *.ASM from \TASM to \MASM: DVCOPY \TASM\*.ASM \MASM\ /M Move all files from drive A to drive B: DVCOPY /M A:. B: - Override Floppy Protection - [/n] Using this switch, you can override the default floppy protection. "n" stands for the level you wish to use. Examples: Copy C:\CONFIG.SYS to A:\MYCONFIG.SYS, using protection level 1: DVCOPY C:\CONFIG.SYS A:\MYCONFIG.SYS /1 Copy F:\*.* D:\TMP\*.BAK, using no protection level: DVCOPY F:\*.* /0 D:\TMP\*.BAK - 8 - DVCopy 1.01 DESQview Aware Copy Utility (c) 1991-92, YossiWare ┌─────┬──────────────────────────────────────────────────────────┐ │ 3.2 │░░░ REQUIREMENTS ░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░│ └─────┴──────────────────────────────────────────────────────────┘ DVCopy requires the following in order to run correctly: IBM PC AT 80286, 80386(sx/dx), 80486(sx/dx) or compatible machine. V20/V30 based machines (XTs) can also be used, but 8088/86 based machines will NOT be able to run DVCopy, or any other executable included with this archive. MS-DOS 3.1 or newer. DVCopy will also run on 4DOS, or NDOS, and can support their file descriptions. SHARE loaded (optional). If you are using DESQview, it is highly recommended you load SHARE (will be discussed later). DVCopy will work with or without SHARE, but will warn if DESQview is used, and SHARE is not loaded. DVCopy was tested on V20/V30, 80286, 80386sx, 80386dx and 80486dx Microprocessors. It was tested under DESQview 2.26 to 2.42, and QEMM-386 5.12 to 6.02 (Including it stealth technology). It was tested under MS-DOS 3.30 and 5.00 (Also loaded-high), and under 4DOS 3.02 to 4.00 (Including revision B1). It was, also, tested on HyperDisk 4.21 to 4.31 (SHAREWARE). No problems occurred during any of these tests. - 9 - DVCopy 1.01 DESQview Aware Copy Utility (c) 1991-92, YossiWare ┌─────┬──────────────────────────────────────────────────────────┐ │ 4.0 │░░░ FILE SHARING ░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░│ └─────┴──────────────────────────────────────────────────────────┘ When running more than 1 program at the same time, there is always the possibility that more than one program will use a specific file at the same time. No harm is done if both programs read the same file. However, if any of them, or even both, is modifying the file, the file will most likely be damaged. The solution, is file-sharing. In order to make file-sharing work, SHARE has to be loaded, and all participating programs should be share aware. DVCopy does. If a task which is not share-aware is being used, and is trying to write to any of the files DVCopy uses, DOS will deny its write-request. Share-aware program would recognize the reason DOS doesn't let it write into the file, and act accordingly (wait). A non share-aware program would recognize the write-deny as error, and warn you about this, or even quit (depends on the program). DVCopy uses the following sharing-modes on the following files: - Original-File reading When DVCopy opens the original file, it will open it for read purpose only, so other programs, who needs to read-only this file will be able to do so. If the original file is already opened, and access to it is denied, DVCopy will wait until access is available. - Destination-File writing When DVCopy opens the destination file, it will open it for write purpose only. It will also make sure other programs will not be able to access this file AT ALL. NOTE: When DVCopy recognizes a file which is locked (by other program that supports SHARE, and is using that file at the same time) it will wait 1 second, and retry. If after 15 retries the file is still locked, it will continue with the next file. - 10 - DVCopy 1.01 DESQview Aware Copy Utility (c) 1991-92, YossiWare A good demonstration of the file sharing can be done in the following way: Copy files using DVCopy from Directory A to Directory B, and on the other task, copy using DVCopy the same file from Directory B to Directory C. You will see how the second copy of DVCopy (Task 2) will wait until access to the file is free. - 11 - DVCopy 1.01 DESQview Aware Copy Utility (c) 1991-92, YossiWare ┌─────┬──────────────────────────────────────────────────────────┐ │ 5.0 │░░░ FLOPPY PROTECTION ░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░│ └─────┴──────────────────────────────────────────────────────────┘ This is probably the most appealing feature in DVCopy, its ability to use floppy drives without causing DESQview to freeze. DVCopy support 6 levels of protection, which provides you most combinations you might want. The higher the protection level is, the slower floppies will work, and the better DESQview will perform. Here is a brief list of the protection levels, and recommendations: - Protection Level 0 Provides no protection to floppies. Use this if, for any reason, you don't want DVCopy ever protect DESQview from slowness. - Protection Level 1 Provides minimal, even too-minimal protection. If the CPU is 100% busy, speed will decrease in 30% maximum (i.e. Total copying time will be 130%, if regular COPY is 100%). DVCopy will not try to keep DESQview running all time, but will drop it some power from time to time. - Protection Level 2 Provides poor protection. If the CPU is 100% busy, speed will decrease in 50% maximum. Use this when using high-speed floppies (usually 5.25"), when the computer is running unattended, and there is no need for synchronized operation (i.e. NOT while transferring files via a modem or a serial port). - Protection Level 3 Provides standard protection. If the CPU is 100% busy, speed will decrease in 55% maximum. It will attempt to keep DESQview running all the time. Can be used on regular speed (2400BPS) transfers, or high-speed transfers, if buffered UART is used (i.e. FIFO NS16550AFN). DVCopy 0.20 used this mechanism of protection. - 12 - DVCopy 1.01 DESQview Aware Copy Utility (c) 1991-92, YossiWare - Protection Level 4 This provides a combination between Level 3 to level 5 protection (which will be discussed later on). If the CPU is 100% busy, speed will decrease in 92% maximum. Will keep DESQview running. Recommended when copying-speed is not critical. On slow drives (3.5" usually) will work better than Level 3. - Protection Level 5 This level provides top-protection. It is very likely you will not even notice any speed reduces. On a 100% busy CPU, will slow down the system in 146%. Is recommended when running many tasks, and / or DESQview requires synchronized time-slices (file-transfer, BBS, etc). Use this level when DESQview speed is really important, and copying speed is not critical. This protection level will continuously give DESQview power, and not in bunches. DVCopy will use the protection level that is set using DSETUP, as default. You may override this default by setting an environment variable, called DVCOPY, which will contain the new protection level. An invalid value in the DVCOPY environment variable will cause DVCopy to use the default protection level, which was set in DSETUP (I.E. SET DVCOPY=2) will change protection level to 2. Using the command-line switch will override the default (DSETUP) AND Environment variable (I.E. DVCOPY /0 ... would force no floppy protection). Refer to section 3.1 for complete list of all command-line switches. - 13 - DVCopy 1.01 DESQview Aware Copy Utility (c) 1991-92, YossiWare ┌─────┬──────────────────────────────────────────────────────────┐ │ 6.0 │░░░ TRADEMARKS ░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░│ └─────┴──────────────────────────────────────────────────────────┘ The following are trademarks, registered trademarks and efforts of their authors (alphabetical order): 4DOS Rex Conn, J.P.
