Help with paths and .zip files

[gbschematic]

I have a problem with unpacking .zip files. The files are not put in the correct directories. Instead, even though all the directories are created correctly, all files go into the directory I'm unpacking to, instead of the subdirectories they belong in. Example:

I have a file called sample.zip. It contains the following files:
folder1\sample.txt
folder1\moretext.txt
pictures\image.jpg
pictures\photo.jpg

I unpack it to c:\unpack by moving the cursor to sample.zip and pressing enter to see the contents, then pressing + to select all, then pressing F5 to copy.

It creates c:\unpack\folder1 and c:\unpack\pictures but the files go to
c:\unpack\sample.txt
c:\unpack\moretext.txt
c:\unpack\image.jpg
c:\unpack\photo.jpg
instead of where they belong.

Can anyone help me with this?

Examine those funny looking checkboxes on the unpacking dialog please.

Make sure "Unpack path names if stored with files" is checked, when unpack dialog window pops up.
