any ideas how to compress .ima files which are strange about 24mb big but only with 3-4mb content . this .ima file was just modified and unneeded files were removed and other additional files were added . now we want this .ima file to be on a usb boot stick. this stick is working proper by having several .ima files for choice. problem is now , this 25mb .ima file , quite big e.g. if adding 10 other .ima files 10x25=250mb .. way to big .

is there some tool to compress/defrag this .ima file so it will be lesser big? we tried winimage , there you can specify a new "size" but this working not proper for us , it says "sector" problem then if we try to start this .ima file .. any other tools or is there a workaround via winimage ?
