MORE INFORMATION
When the Setup Wizard compresses files for assembly into disk images, it
ensures that the files do not exceed the limit (in bytes) defined by the
SplitSize value in the Preferences section of Wzsetup.ini. By default, this
value is 363,520.
Files that fall below this limit are renamed with a $ in the filetype. For
example, a 234,738-byte file named Mydata.dbf is compressed into:
MYDATA.DB$ 61,638
Files that exceed this limit are chopped into pieces. The pieces are given
a generated filename and an extension that indicates the order in which
they are re-assembled when installed on the target computer. For example, a
4,415,168-byte file named Mydata.fpt might be divided and compressed into:
56600245.001 263,446
56600245.002 344,833
56600245.003 335,156
56600245.004 323,052
56600245.005 273,779
During installation on the target computer, these files are decompressed
and reassembled into Mydata.fpt.
If you need to reassemble this table without running the setup program, you
can use Expand.exe to expand each piece; then copy the expanded pieces of
the memo file into the final memo file:
EXPAND MYDATA.DB$ MYDATA.DBF
EXPAND 56600245.001 MYDATA.001
EXPAND 56600245.002 MYDATA.002
EXPAND 56600245.003 MYDATA.003
EXPAND 56600245.004 MYDATA.004
EXPAND 56600245.005 MYDATA.005
COPY MYDATA.001+MYDATA.002+MYDATA.003+MYDATA.004+MYDATA.005 MYDATA.FPT
To determine the original name of a compressed file, refer to the
Application section of the Setup.inf file that is written to DISK1 (or
NETSETUP) of the disk image directories:

The default SplitSize value of 363,520 is held over from the FoxPro version
2.6 Setup Wizard, which was able to generate 360K disk images and needed to
ensure that files would not exceed the capacity of a 360K disk. While the
version 3.0 Setup Wizard does not generate 360K disk images, the SplitSize
value of 353,520 provides improved flexibility when assembling files into
1.2-MB and 1.44-MB disk images.
The version 3.0 Setup Wizard is able to split a file into hundreds of
pieces by using a numeric file extension. The file extension may extend
from 001 to 999, but a directory limitation (or setup limitation) may be
encountered before getting that far.
The SplitSize setting may be increased to cause the Setup Wizard to create
larger chunks when it splits large files. Do this by modifying the
SplitSize setting in Wzsetup.ini. Do not use a setting greater than the
number of bytes that will fit on 1.2-MB disks (or 1.44-MB disks). Some
experimentation and testing may be required to arrive at settings that work
well for the specific application.
