Instructions for splitting up a large file to multiple floppy diskettes
Here is the syntax for using the CHOPPER program for splitting a file. (This information can also be found by running CHOPPER.EXE with no parameters)
CHOPPER file [dest] [/K:size]

Where:

file : File name to be split.
dest : Destination for the split files. (default A:)
size : Split file size in KB (default 1024)

1. Open a DOS command prompt. This is especially important for OS/2 and Windows NT users. (To open a DOS command prompt in Windows NT, click Start -> Run and type COMMAND.COM. then press enter.)
2. Change to the directory where the large file that needs to be transferred is located.
3. Enter the following command:
   CHOPPER filename_to_be_transfered
   
   The chopper program will tell you how many BLANK, FORMATTED diskettes are needed and will offer the option to stop and prepare them to ensure that the diskettes are blank, with no important data, and to allow them to be formatted if necessary. When you have the diskettes ready, simply retype the CHOPPER command given above.
4. When prompted to insert diskette #1 insert one of the BLANK, FORMATTED diskettes into the floppy drive and press Enter to continue. CHOPPER will then copy itself to the first diskette as the file UNCHOP.EXE.
5. When prompted, remove the diskette and label it as Diskette #1. Follow the prompts on the screen for the next diskette(s). When it has finished splitting the files, it will give you the command to run on the other computer system to which you wish to transfer the file.

Instructions for restoring a chopped file from multiple floppy diskettes
Do the following on the target computer that you wish to restore the file to.

Here is the syntax for using the CHOPPER program for joining a split file back together. NOTE: During the splitting process, CHOPPER.EXE will copy itself to the first diskette as UNCHOP.EXE. (This information can also be found by running CHOPPER.EXE with no parameters.)

UNCHOP [file.000] [dest]
file : File name to be joined
dest : Destination for the split files. (current directory will be default destination if the dest parameter is not specified)

1. Open a DOS command prompt. This is especially important for OS/2 and Windows NT users. (To open a DOS command prompt in Windows NT, click Start -> Run and type COMMAND.COM then press Enter.)
2. Create a TEMP directory by typing md TEMP and press Enter.
3. Change to the TEMP directory by typing cd TEMP and press Enter.
4. Put Diskette #1 into the floppy drive and enter the following command:
   A:\UNCHOP A:\filename.000
   Then, follow the prompts that appear on the screen.

NOTE: You must put the .000 at the end of the filename!

Solution #2
Another solution to this problem is to use PKZIP to compress the file onto multiple floppies and then use PKUNZIP to restore the file onto the target computer. To download v2.04g of PKWARES Zip utilities, PKZ204G.EXE, click here . These utilities will run on DOS, Windows 3.1, Windows 95, Windows 98, Windows NT 4.0, and OS/2 Warp.

Installation instructions for the Zip Utilities

1. Download PKZ204G.EXE to a temporary directory.
2. Execute PKZ204G.EXE. This is a self-extracting zip file.
3. Copy the following two files to the target folder using the following command:
   COPY PKZIP.EXE target_folder
   COPY PKUNZIP.EXE target_folder

• target_folder for DOS users, C:\DOS or the drive and directory where DOS is installed.
• target_folder for Windows 3.1/95/98 users, C:\WINDOWS or the drive and directory where Windows is installed.
• target_folder for Windows NT 4.0 users, C:\WINNT or the drive and directory where Windows NT 4.0 is installed.
• target_folder for OS/2 users, C:\OS2 or the drive and directory where OS/2 is installed.

Instructions for backing up a large file to multiple floppy diskette
Do the following on the computer system that you wish to transfer the file FROM.

1. Open a DOS command prompt. This is especially important for OS/2 and Windows NT users. (To open a DOS command prompt in Windows NT, click on Start -> Run and enter COMMAND.COM.)
2. Change to the directory where the large file that needs to be transferred is located.
3. Depending on the size of the file, have several blank floppy diskettes available. As a general rule, have a diskette available for every megabyte of file size, e.g. if the file is 4.313 MB in size, have 4 floppy diskettes available. Label each diskette as Diskette #1, Diskette #2, etc.
4. Run the following command exactly as it appears below. Be sure to include the double-quote marks around the -&f. This is REQUIRED for Windows NT users.
   PKZIP "-&f" A:\TRANSFER.ZIP filename_to_be_backed_up
   Then, follow the prompts that appear on the screen.
5. If you do not have PKUNZIP.EXE on the target computer system, do the following. (Test by typing PKUNZIP and pressing the Enter key. If the file is on the system, the screen should fill with information about how to use PKUNZIP.)
   a. Insert a blank diskette into the floppy drive.
   b. Run the following command:
   COPY PKUNZIP.EXE A:\

1. Open a DOS command prompt. This is especially important for OS/2 and Windows NT users. (To open a DOS command prompt in Windows NT, click on Start -> Run and enter COMMAND.COM.)
2. Create a TEMP directory.
3. Change to the TEMP directory.
4. If PKUNZIP.EXE is not already on the system, do the following. (Test by typing PKUNZIP and pressing the Enter key. If the file is on the system, the screen should fill with information about how to use PKUNZIP.)
   a. Insert the diskette with PKUNZIP.EXE into the floppy drive.
   b. Run the following command.
   COPY A:\PKUNZIP.EXE target_folder
   
   Where:
   

• target_folder for DOS users, C:\DOS or the drive and directory where DOS is installed.
• target_folder for Windows 3.1/95/98 users, C:\WINDOWS or the drive and directory where Windows is installed.
• target_folder for Windows NT 4.0 users, C:\WINNT or the drive and directory where Windows NT 4.0 is installed.
• target_folder for OS/2 users, C:\OS2 or the drive and directory where OS/2 is installed.

5.Insert the last diskette that you just created into the floppy drive.

6. Run the following command to restore the file:
PKUNZIP A:\TRANSFER.ZIP
Then, follow the prompts that appear on the screen.

NOTE: Systems running CardSoft PCMCIA drivers may experience problems when running PKUNZIP. Use the following command instead. For further details, click here .
PKUNZIP -) A:\TRANSFER.ZIP
