PLEASE HELP! HOW do you open a .001,.002, and .003 file?

Question

I dont know how to open it.

Is there I program I have to install in order to open?

Answer 1

these files are split files. They have to be joined together  by using the same program which split the files.If it is a video then you can try opening it with media players iot will open. But if it is a software then you cannot open it until you have merged all the files.

Answer 2

What program made the files or where did you get them?

That would be a clue as to what you need to open or use them.

Answer 3

Try using a free program called "HJSplit." I use it all the time to join those thypes of files.

Answer 4

there is an archiving program, called (win)RAR, that produces such files when it has to make multi-volume archives.

the first file in the archive is called 'whatever.RAR' and the next ones:

'whatever.001'

'whatever.002'

'whatever.003'

... and so on.

any (un)archiving program should be able to open such files, but it's best to work with the original. (i.e. winrar).

file splitting software also produces such files...

try to open the first file with notepad (be sure NOT to check the "always open with this program" option!) and see if there is some readable information in the first few bytes of the first file. it may be a good place to find out more about these files.
