Hello Gerard, Good idea, but problematical in that like you mention, it is not zip compatible. For example previously I used to use MS Backup which stored in QIC format. Now times have changed and QIC is no longer supported hence my old backup disks can only be retrieved using Win98 on another computer. With ZIP you dont have this problem. Which, IMHO is no big deal as we can use REFRESH or UPDATE which works well for most desires. However, there is an interesting development by a very clever Singaporean who is happy to work with you if you want to contribute. His project is called RESOURCE and does everything you mention.
