I have a VOB file with two audio tracks (jap/fr) but I'd like to keep only the first one, and definitely erase the 2nd.

Jagabo: is it ok if I demux like in this tutorial?
About remuxing: usually, when I join two TS files, I use the command line. Can I do the same to remux those extracted video and audio tracks?
After that I have a .mpg that I simply change to .vob (I just modifiy the extension)

I succeeded to demux my file with DGIndex. Now I have this.

Then, I did this, but it don't work, I only have audio on the final file. I also lost the subtitle.
Btw, I didn't find any dedicated muxing tool to remux my extracted files.

Copy/b isn't muxing, it's appending.
Copy/b copies all the first file to the output file, then appends all of the second file. That is not multiplexing. And even though you specified .VOB as the output file it is not a VOB file. (You can name a file with any extension you want, that doesn't make it that type of file. For example, rename your VOB file as .XLS and try to import it into Excel. It will fail miserably.)
Multiplexing (muxing) copies a small amount of video (say, 1 frame), then a small amount of audio (1 frame worth of audio), then another small chunk of video, another small chuck of audio, etc. The video and audio are thus interleaved throughout out the file which makes it easier for a player to play the file. The muxer also follows the container's specification for how those chunks are organized and identified within the file so a player (or other program) can identify them. Different A/V containers use different methods of organization.
I already gave an example using ffmpeg to remux from your source VOB directly to a new VOB with only the first audio channel. To mux the demuxed video and audio files you would use something like:
ffmpeg -i video.m2v -i audio.ac3 -vcodec copy -acodec copy output.vob
I searched some tutorials about ffmpeg but I still don't know how to make it work.
I double clicked on the .exe file but nothing happened. I even didn't succeed to open a comand line from inside a folder.
Isn't there a programm to remux by just dropping the two files and done?

Since you have mentioned a subtitle, DGIndex has not demuxed that from the vob. You need other tools such as vobsub for that.
Then you have to mux audio, video AND sub back and I guess the easiest way to do that is via dvd-authoring such as avstodvd.
But, sorry, this is all a lot of work just to remove an un-needed audio track which most players, vlc being just one, will happily ignore.
Even so I still do not buy in to your argument. Unless I read your OP wrong the track you want to remove is NOT the default one, All players should select the default one automatically.
About subtitles: ok
- files from folder#1: audio is fr1/jp2 (dragon ball)
- files from folder#2: audio is fr1/jp2 (space adv. cobra)
Settings I did on the files of the folder#1 will be not valid for the files of the folder#2 since those files was ripped from different DVDs.
The settings I did is the following:

>First step (audio track) is effective case by case as I described below. Number ''1'' on dragon ball will set ''jp'' by default, but same number ''1'' on space adv. cobra will set ''fr'' by defaut, or sometimes even no audio at all concerning other mangas, or movies...
p.s. second step (audio language) doesn't change anything, even if I tape 1, 2 or empty.

The subtitles in a VOB file are not SRT format. They're not even text. They are pictures that are overlaid onto the video during playback.
I have to agree with DB83. This is a huge waste of time just to remove an unused audio track from a VOB file. If you're looking to reduce the files size, removing an audio track will only give you a few percent reduction.
VLC, but if I want to watch a movie, the first language will also change in a case of a mutli language file. Then, I'll have to set this again especially for some movies only.
So, thanks to both of you, I already succeed to demux and do elementary streams for audio and video with DGIndex.
Now I'd need to extract the subtitle file but I currently don't know how to proceed/which programm.
Then remux all, idem.
Even if I've to use three programms to do this, it would worth.
Thanks for your help
Try reset that first audio setting to -1 from 1.
Use the audio menu to select the desired track and not rely on preferences.
And I think the OP wants a vob not a mkv
IFOEdit, which produces the files and folders for a menuless DVD. If there are multiple VOBs and you only want one big VOB instead of a DVD, then use VOBMerge to join the VOBs.
[Edit] I just re-read the description for IFOEdit which says "IFOEdit allows users to parse VOB files, remove and add video, audio and subtitle streams to VOBs." I have not tried doing that with IFOEdit, but perhaps IFOEdit is all you really need.

I just took a look at IFOEdit myself,
it looks as if the "VOB extras" button will do it. Open this dialog, select "strip streams" and provide the path to
where you want it to create the new version. When you select "OK", it gives you an opportunity to deselect unwanted streams
Been a while since I used ifoedit. But surely this works by reading the ifo from a ripped dvd. The OP just mentions 'vob' although he later, confusingly, writes about 'folders'.
But if he does have full dvd folders he will surely have to go down this route since I would have thought that randomly editing individual vobs in a folder will result in non-working files that rely on the original ifos.
In some cases, VOBs can be successfully played as stand-alone files although that is not best practice. However, I forgot that there will be a problem viewing subtitles because the CLUT (color look-up table) is stored in IFO files. Without a CLUT to supply and map the colors to be used, sub-picture subtitles will be solid green, at least that has been my experience.

You could be right, but if it's just a standalone vob, why not covert it to mkv?
It's hard to understand what's going on because the OP hasn't given any much context
