[Total noob - 7-zip help needed]

I decided to start using Ketarin to keep my thumb drive up-to-date. It's full of installers (.exe) and Portable Appls (.zip files, not .paf, although I'll get to .paf soon enough).

 

Right now my thumb drive looks like this:

 

%\PortableApps\

 

%\Tookit\

%\Tookit\7z.dll

%\Tookit\7z.exe

%\Tookit\Ketarin.exe

%\Tookit\System.Data.SQLite.DLL

 

%\ZipFiles

 

Now I only have 1 program so far - CCleaner - because I'm trying to figure out how to get this to work. I have successfully gotten ccsetup.zip to extract to %\ZipFiles\ccsetup229.zip. The problem comes when I want 7z to extract it to %\PortableApps\CCleaner.

 

Here is the command I am executing after downloading:

 

7z x {file} -o"{root}PortableApps\CCleaner\" -y

 

Which is what I managed to scrape together from posts on here. Is this correct? Why isn't it extracting? I'm probably making a pretty noobish mistake, but I'd appreciate any help.

 

Thanks.

 

EDIT: I managed to figure it out after some more experimentation. I needed:

 

7z x {root}ZipFiles\{file} -o"{root}PortableApps\CCleaner\" -y

 

Thanks for anyone who looked. I'm sure I'll be back with more noobish questions before I get the hang of this.
