Cannot export case

I have imported more than 100000 rows in the case. And the case is on the process on increasing day by day. Now I need to export all the case again but it is not allowing me to export the case it says "This export contains 113070 rows. Please change the filters to be less than 100000 rows".....How can I export the case.. is there any options????

You can use the date range filter to split the export in two. For example, do one export including cases modified on or before May 1st (or some apporpriate date), then a second export including cases modified after that date. Then you can join those two exports in excel.

If you will frequently be exporting large numbers of cases, you might also look in to the data export tool, which makes this process more manageable at a large scale:
