How to Split Large PST files into smaller PSTs?

As Outlook data grows, the PST file can become oversized and more prone to corruption. Using the SysInfo PST Splitter helps prevent this by breaking the large PST into smaller, organized files. You load the PST file into the tool, and it scans the entire structure—emails, contacts, calendars, folders—so you can see what you’re working with. You then select a splitting method: by file size (like creating multiple 500 MB PSTs), by date ranges, by folders, or even by specific sender email IDs. Duplicate emails can be removed, and new PST files can be protected with a password. Finally, you choose where the resulting files should be saved, and the tool creates several smaller, safer PST files.

If you're trying to figure out how to split large PST files into smaller PSTs, the easiest and safest way is to use a dedicated PST splitting tool. Large PST files often lead to slow Outlook performance, corruption issues, and difficulties in accessing data. Manual methods are limited and risky, especially when handling oversized files. A reliable solution is the Cigati PST Splitter Tool, which allows you to divide a large PST file into multiple smaller PSTs based on size, date, folder, or even specific email IDs. It ensures data integrity and prevents corruption during the process.
