See thumbnail previews of your compressed files. The tool creates thumbnails for your ZIP, RAR, CBZ, and CBR by using the first image found in the archive. It integrates itself with the Windows shell menu and supports JPG, ICO, PNG, BMP, TIFF, GIFF images as well as ZIP64 archives. It doesn't work with encrypted archives.
Windows Explorer does not show the thumbnail preview of all image and video formats. CBX Shell is designed to easily change file extensions between ZIP/RAR and CBZ/CBR. CBX Shell provides Windows Explorer thumbnail and info tip extensions for image archives.
I can see the thumbnail of a *.ggb file when I change the extension from ggb to cbz, so the file test.ggb shows the icon of GeoGebra ever, but test.cbz shows an internal thumbnail of an GGB file.
This can be very very useful for million of GeoGebra users.
Please add GGB extension to cbxshell.
It will this will make us very happy.
