I have downloaded a bootable image of Ubuntu (7.95Gb .img file) for a Parallella (minicomputer), but its too big to fit on my 8GB micro sd card (which actually is only 7.8 GB!).
I would like to remove some software from this image like Libre Office. However when I mount the image on a mac the folder appears to be empty. Except for a few hidden folders (.Trashes, ._.Trashes, .fseventsd) there is nothing.
Is there a way to remove some of the content of this .img?
