How to play .avi or .mkv video chunks like .mkv.001, .mkv.002, .mkv.003, .mkv.00...? How to get entire movie in a single file?

Usually Movies (Videos files) have huge sizes, so these are first splitted/divided into small chunks such as .avi.001, .avi.002, avi.00.... or .mkv.001,.mkv.002, .mkv.00.... before uploading online on a Website. 

There are two methods by which you can combine or join or merge these chunks into a single file:

First method: there are software such as HJSplit (from http://www.freebyte.net/download/hjsplit.zip), that can be used for splitting and merging.

1. First, ensure that you are having all the chunk files in a single folder.

2. Open Command Prompt and navigate to the above folder using "cd" command.

3. type following command:

copy  /b  moviename.mkv.001+moviename.mkv.002+...moviename.mkv.00N   moviename.mkv

[where moviename.mkv.00N  is the last chunk file]

 4. Wait for few minutes till it gives: "file(s) were copied successfully" message.

Now, if your VLC Player or Winodws Media Player (with right codec installed) is playing the newly created file  moviename.mkv, then you can delete the file chunks. It will save your disk space!!
