RarExplorer is a P3dO plugin.

RarExplorer automaticaly lists archives files content and display them in P3dO thumbnail view and Information tree.

This function does not actually unrar any data, its purpose is solely to display a RAR content.
Instead of displaying a RAR icon, RAR Explorer displays each RAR archive with first picture encountered in the file if any.
RarExplorer show the first image taking into account the alphabetic and RAR folder hierarchical order, i.e pictures at the root of the RAR files are first.

RarExplorer showing a thumbnail image:

Each time you double-click on an archive file, RarExplorer will expand its content in P3dO. If you double-click on the RAR file again the archive is unexpanded.
When a RAR archive file is clicked RarExplorer display a thumbnail view of the RAR archive content with a small RAR icon for each file. As shown:

The content can show icons, pictures -as above- or 3D files depending on the ability to decode the files formats.
Currently all 3D file formats and pictures are Rar through viewable with the pro version. The freeware version is limited to 3D Wavefront OBJ and 2D RSR, PNG pictures.

Unrar to the disk

(not supported yet)

RarExplorer doesn't add any menu item in your P3dO application.
Instead RarExplorer plugs into the "Open" command. Thus "Open" on a RAR will expand that RAR into P3dO thumbnail view (without unzipping), see above for details.
