this is a crap idea! if you compress a cluster then the cluster is not full anymore. if you move other data in there then, then you need much time to decompress the whole thing again... in my opinion a silly idea, not worth the work on it. by the way, coding this is quite complicated, too, because it has to run as a storage filter driver. Don't try it, just do it! ;-)

Hi Alexender Thanks for the suggestion and replay. I agree with u but what i just want to do. I read a cluster using ReadFile() function and keep it in buffer . Now my question is how to compress this data which is in buffer so that if i write it any other place as a backup. It takes less memory space in HDD or any other storing device. I am to compress files but cluster by cluster because i want to store the backup of this file in bytes(row) form not in file form [compressed file takes clusters again wastage of space ] . This might be crap idea. But u would be able to help me , i'll be thankfull. Now Ball is in your goal:)
