How to join various video files into one video file without any software…..?

In this article I’m going to show you
how to join
different video files like as MPEG, DAT, MPG,
mp4, AVI etc. and convert it one video. You can
join your video files using just the windows
Command Prompt. No need of any video joining
software’s. The best method to follow is shown
below.
Step-1:
For example if you have 3 videos in your hard
drive root drive: video1.mpg, video2.mpg and
video3.mpg just rename them to a, b, and c
(just the letter without the file extension).
Example:
Rename ® video1.mpg ® a (without .mpg)
Rename ® video2.mpg ® b (without .mpg)
Rename ® video3.mpg ® c (without .mpg)
Step 2:
Now open Command Prompt ( winkey + R) or
Start–>Run–>type “cmd”.
Step 3:
Then type your location like “C: , D: , E: etc.”
Step 4:
Type this code: ® Copy /b a + b + c
videoname.mpg and press enter
Or
copy /b "C:\File.mp4" + "C:\File1.mp4"
CombinedFile.mp4
Step 5:
Now wait till you see: 1 files<s> copied, then
type exit and press enter.
That's it. You are done! Hope you enjoy this
trick… @@@
Note: If you want to join two files then those
files must have the same extension and if you
change directory C:\> to D:\> then, you just type
the drive name like "D" and colon like D: then
press enter.
