You should be able to browse all your content using the CTA "Content Manager".
Content is divided into two areas: Template and Custom.
You can not delete, or save to the Template area but can you in the Custom area.
Also, some content (usually body/face parts) will only show up in the Content Manager when you are in the Character Composer mode.
While using the CTA Content Manger you can also right click any item and use the "Find File" to open a window to that files location.
Content is also subdivided into various sections such as Characters, Props, Motions, etc. as indicated by the various Tabs in the Content Manager.
