Could you be more specific? Do you mean opening foo.tar.gz inside bar.tar.gz and being able to extract a file from it?

im trying to extract a specific file from an archive *.tar which is inside an archive *.tar.7z

So you have foo.tar inside bar.tar.7z, and you want to extract baz from foo.tar? Doesn't it work if you open foo.tar from within bar.tar.7z and then extract the file from it?

exactly...... thank you for your quick reply

Has it worked then? Can this bug be closed?

Ok. That's an old thread.. Anyway, I feel sharrana's pain and was going to open this exact same issue.

Let me try to explain my way.. Supose I have a file A compacted as B.zip which is compacted as C.tar.gz (A -> B.zip -> C.tar.gz)

Current behaviour:
1. Open file C.tar.gz, see it's content (B.zip)
2. Click to open B.zip, see that KDE's embedded viewer is opened
3. You can't extract B.zip's content (A) because embedded viewer is read-only

Wished behaviour:
1. Open file C.tar.gz, see it's content (B.zip)
2. Click to open B.zip, see another instance of Ark launched to open B.zip
3. Now you can extract B.zip normally

I believe the initial use of embedded viewer was because Ark doesn't support file modification (editing/ a .txt directly from the .zip and have it updates). But that is another thing that I miss a lot

Actually you can extract file A by drag-and-dropping it on Dolphin. But I agree that it should be easier than that, so I'm confirming this wish.

I'm not sure about this. The user can just right-click B.zip and choose "Open". This will cause B.zip to open in a new Ark instance.

With Ark 15.12 the user can just right-click the nested archive and choose "Open" to make the archive open in a new Ark instance.
