I have a tar archive in which I have a directory which I need to extract in a given directory.
For example: I have a directory 

> 
> TarPrefix/x/y/z
> 
> 
> 

in a tar archive I want to extract it in a given target directory for example: extracted/a/ this directory should contain all the files and directories contained in directory TarPrefix/x/y/z.

```
subdir_and_files = [  tarinfo for tarinfo in tar.getmembers()
                      if tarinfo.name.startswith("subfolder/")
                   ]

```

to get the list of all the members in the directory path "subfolder/" and then I extract it using `tar.extractall(extracted/a,subdir_and_files)`
but it extracts all the members with their directory path For example this results in extracted/a/x/y/z.
Could you please help me in extracting these files in the given folder.
