Struggling with giant Outlook PST files that slow everything down? The Aryson PST Splitter Tool makes it easy to break large PSTs into smaller ones by size, folder, or date. You don’t need Outlook to use it, and it handles both ANSI and Unicode PSTs seamlessly. It keeps your folder structure and metadata intact and even lets you preview files before splitting. Moreover, it supports batch splitting—so you can split up multiple PSTs in one session.
