Split PST is a lightweight software application built specifically for helping you split large PST files into smaller ones. The PST file format is generated by Microsoft Outlook and Exchange, and stores personal information about contacts, messages, and addresses.

The layout is intuitive enough to be configured without having to consult a help manual or watch online tutorials. Plus, it offers support for a step-by-step approach, so even rookies can master the entire process with minimum effort.

The program gives you the possibility to select the Outlook format (Microsoft Outlook 2000/2002, MS Outlook 2003/2007/2010), and pick the splitting method, namely by size, date, year, or folder.

Files can be uploaded into the working environment using the built-in browse function, so you cannot rely on “drag and drop” operations. Additionally, you are required to pick the destination folder.

If you want to split PST files by size, you are required to specify the value in MB. For example, if you have a PST file of 100 MB size and you have entered 25 MB as a splitting size, the application automatically create 4 PST files each 25 MB in size.

Split PST is able to split all items of Outlook mailboxes, such as emails, contacts, calendars, journal, tasks, and preserves an accurate information (e.g. sent date, received date and time, sender’s name, receiver), as well as split very large PST items.

During our testing we have noticed that Split PST carries out a task quickly, provides very good output results, and no errors showed up throughout the entire process. It doesn’t eat up a lot of CPU and memory, so the overall performance of the computer is not affected.

All in all, Split PST offers an intuitive interface and handy set of parameters for helping you split PST files on the breeze.
