Are they all the same format? If they're all text, the basic format is a MS-DOS command line like: Copy file1.txt + file2.txt + file3.txt + file4.txt output.txt If you have that many files, you might want to create a batch file that would copy groups of five individual files to intermediate output files, then copy all of the intermediate output files into a single, final output file, then erase all of the files it created. -----Original Message----- From: bookport-bounce@xxxxxxxxxxxxx [mailto:bookport-bounce@xxxxxxxxxxxxx] On Behalf Of Barrett, Don Sent: Tuesday, January 25, 2005 2:35 PM To: Bookport (E-mail) Subject: [bookport] Concatenating files I have around 20 little files I want to put together into one large file = and send to the bp for reading.
