This OST file splitter is an amazing solution that can reduce OST files into smaller segments. It makes possible for all users to handle an oversized OST file by splitting each file on basis of year, date, size and folder. However, MS Outlook installation is mandatory while working in a pleasant way. I must say, it is a perfect way to divide OST data which is large in size. Thanks a lot.
