How to concatenate several archives:
(I´m translating back to English from a Spanish version, adding my comments)

a) Under DOS
Valid for DOS up to Win95, I´m in doubt about Win98 as DOS is no more there.
Just a emulator program. Worse in Win2000 (is NT)
 
COPY [/A | /B] origen [/A | /B] [+ origen [/A | /B] [+ ...]]
    [destino [/A | /B]] [/V] [/Y | /-Y]

  origen      [path/]+input files.
  /A           ASCII text files (H00 is EOF).
  /B           binary files (disregards H00 as EOF, takes filelength form the header.
  destino    [path/]output file 
  /V           Write Verify 
  /Y           If output file exists does not ask for permission to overwrite
  /-Y          If output file exists ask for permission to overwrite

To concatenate files, specify one output file, specify several input files
using wildcards (?? or *)  or the form:
(archivo1+archivo2+archivo3).
The first one without the plus sign for a new output file.
Up to DOS 6.22 if the first file has the plus sign it means that the input
files were copied past the end of the output file.

b) A little programming (Basic or Pascal, VB or Delphi)
    (Pseudo code or Skeleton only)

*Create SplitFilesList(qtySplitFiles)   as a string array with the 
                                                    names of the split files.
Open "MyNewPSfile" as #1 for Append
For filenum = 1 to qtySplitFiles 
    Open SplitFilesList(filenum) as #2 for Input
    Do until (EOF#2)
        Read #1 
        Write #2
    EndDo
    Close #2
Next filenum
Close #1

Can be a lot more time consuming, but you can control
the whole process.
