How to Join Files with 001 Extension Using HJSplit File Splitting Program

I have a list of files with extensions avi.001, avi.002, avi.003 and that goes on to avi.008
These list of files with file extension 001,002,003,...,008 belong to download parts of a program, or may be part of movies, etc.
In fact, these files with 001 format are splitted parts of a file with huge size.
Since it makes it difficult to copy, move or download files with big sizes, it is a wise step to split files using a file splitting program.

Here is a list of files with extension .001, .002, .003, etc.

If you do not know that these 001 files are parts of a file, you might think that you require a 001 player to play movies of files with 001 file extension.
Don't forget there is not such 001 player to play splitted files .001, 002, etc.
There is not also a 001 format for files, this is just naming splitted file parts in order.
They are the outputs of a file split program like HJ-Split.

The perfect tool for merging and getting together splitted parts of huge sizes is the file splitting program HJSplit.
There are many software tools available to file split also for free dowload if you make a search on the web with file split keywords.
