cmd command prompt

[james636]

Can someone give me a simple guide on how to use the cmd command prompt to join files. I don't know how to this at all, so please when you are explaining, don't assume that I know what you mean. In other words, Don't try to impress me with big words and complicated terms. Speak English!!

Try filename + filename joinedfilename

(using only spaces or + in between filenames)

This method worked in DOS and pretty sure it still does in all Microsoft including XP. Use complete filenames with extensions to be sure, and in same directory.

Just to clarify a bit more:

Example 1:
Say you want to join text files named 'filename1.txt' & 'filename2.txt' and create 'filename3.txt',
you can use ..

copy "filename1.txt" + "filename2.txt" filename3.txt

Example 2:
Say you want to join many text files 'fn1.txt', 'fn2.txt', 'fn3.txt', 'fn4.txt.' etc and create 'new.txt',
you can use..

copy "fn*.*" new.txt.

Example 3:
You want to join non-text files, (called binary files),
you need to use the '/b' option in your copy.
e.g.

copy /b "movie.mpg.001" + "movie.mpg.002" + "movie.mpg.003" wholemovie.mpg

OR

copy /b "movie.mpg.*" wholemovie.mpg

NOTE: Not all file types will be able to be joined this way, many have header information at the front of the file which needs to change if information is added. For example you can't join AVI files this way, you must use AVI joining software.
