Big PST files make Outlook slow, and sometimes it even stops working or takes too long to open emails and folders. SysInfo PST Split Tool helps solve this problem by dividing large PST files into smaller and easier-to-manage parts without affecting the original data. One of the main features is Split by Size, which allows users to set a specific size limit, such as 200 MB, 500 MB, or any custom value. The tool then automatically breaks the large PST file into multiple smaller files based on that limit. This helps reduce the load on Outlook and improves overall performance. Another useful feature is Split by Date, which enables users to divide emails according to a selected date range. This makes it easier to manage old and new emails separately and improves accessibility when searching for specific data. Additionally, the tool includes a Remove Duplicate Emails option, which ensures that repeated emails are not included in the new PST files. This helps keep the data clean, reduces file size, and avoids unnecessary duplication.
