After several attempts at splitting a .djvu file, i was successful in doing so. It was using a right-click feature which segregates the respectives files, into separate directories with the same .djvu file associations but in smaller file sizes. I tried to experimentate with opening the newly created smaller files, which also cleared any doubts i've had on this feature. However, when i specifically zip up a range of pages into a .rar file exhibiting a meagre file size of 500 kbs and sent it over gmail i found that the lizardtech browser failed to open them up. Whereas at my own desk, i could open them with cinch. May i know what may be the reasons this blunder. Furthermore if any solutions to the problem would be greatly appreciated, as this means that i could improve work efficiency both at home and office?

Have you tried saving the .rar files onto the work PC, instead of opening them from the browser and then opening with winrar?
