Is your Outlook running slow because of a huge PST file? Try the Aryson PST Splitter Tool to quickly divide your large PST file into smaller parts. It lets you split based on file size, folder name, sender ID, date, or year. When you get the message that the Outlook PST file is too large for a destination file system, this tool comes in handy. It works with both ANSI and Unicode PSTs and even supports password-protected files. You can view your data before splitting, and everything stays safe—no loss of attachments, folders, or formatting. It's a great solution for anyone who wants to manage large Outlook files easily.
