I am trying to upgrade my Cisco router but have hit a snag. The image that I am trying to upgrade to is roughly 18.5 mb and the image currently on the router is about 12 mb. The router only has 24mb of space, though and there are other files that are on the router. What I have in flash besides this image is home.tar, sdm.tar, home.shtml, common.tar, sdmconfig-8xx.cfg and SDM_Backup. Is there any way to get rid of any of these files and still have the router work?
