I have a zip file (somezipfile.zip) with the following contents in it:

dir1/subdir1/somefile1.txt
dir1/subdir2/somefile2.txt
dir1/subdir2/somefile3.txt
dir1/somefile3.txt
dir1/somefile4.txt
dir2/somefile5.txt
dir2/somefile6.txt

Lets say I unzip this to my home directory so now I have:

/home/me/dir1/subdir1/somefile1.txt
/home/me/dir1/subdir2/somefile2.txt
/home/me/dir1/subdir2/somefile3.txt
/home/me/dir1/somefile3.txt
/home/me/dir1/somefile4.txt
/home/me/dir2/somefile5.txt
/home/me/dir2/somefile6.txt

Now I do rm -rf /home/me/dir1/subdir2:
/home/me/dir1/subdir1/somefile1.txt
/home/me/dir1/somefile3.txt
/home/me/dir1/somefile4.txt
/home/me/dir2/somefile5.txt
/home/me/dir2/somefile6.txt

How can I unzip ONLY the subdir2 folder and the files it contains into the /home/me/dir1 folder without freshening or touching the other directories?

Also consider I may have subdirectories within subdir2 as well.

All responses are greatly appreciated. Thanks in advance.
