Hello.
I have some "Rar" files like :

x.part1.rar , x.part2.rar and...

In Windows OS and with "WinRar" after Extract I just have one file that contain all file but how can I do it In Linux?
These files are split and after extract merge automatically.

Thank you.

Programs like unrar automatically detect if you have a multi-volume archive and will search for the other parts in the current directory to extract the data from them.

You can just user unrar from the command line, give the first file as an argument and it will automatically extract from all the files. I think that some of the GUI tools will do the same also. It should be noted though that the non-free version of unrar may be needed to do this.

I did :

unrar -x x.part1.rar

But problem not solved.

I used Peazip too but not solved too

As I mentioned, you may need to non-free version of unrar, if you don't already have it. There's also the possibility, of course, that you don't have all the parts or they're not all complete.

You are a seasoned member here, you should know already that "problem not solved" is not something that helps us to help you, especially since I and other members already asked you to provide essential information in other threads repeatedly.
Since you not seem to be willing to help us to help you I am out of this thread.

As I said, Files are complete and can extracted via Windows very nice.

Can you show me which information?
If you want to ask same question can you tell me which information you provided?

Well, all I can do is repeat that you might want to check you have the non-free version of unrar installed because my experience was that the free version didn't work for multi-part archives but the non-free version did. In Debian it seems you get the non-free version by installing the unrar package provided you have your system configured to accept non-free software but the free version may have been installed instead as a dependency while installing something else?

As I told you before, we need as exact information as we can get.
This won't work:
- doesn't work
- "problem not solved" without exact explanation of the problem

This will work:
- I get the error "{copy in the exact error message you get}" when running this command
- I expect the command to do this, but instead I get {exact description of what you get}

So in your case, what exactly happens when you run the command? You don't tell us if it returns an error mesaage, if it extracts only parts of archive, ... .

It extract just some parts and not all of them.

Are you sure that the parts that are not extracted are parts of the archive you want to extract? If they are then unrar should throw error messages.

It show me :

so extraction failed. That means either the archive file was corrupted or the utility you use cannot find the next part of the archive or disk full or probably something else.
Can you tell us what will
dpkg -l unrar
respond?

this would have helped in the FIRST POST
you have BLANK SPACES IN THE FILE NAME

this can and dose cause problems

yes they do, i had a similar problem here, and the solution was here

for you it would probably be
good luck
