Frequently Asked Questions

Why should I split a large PST file?

Splitting a large PST file helps prevent corruption issues, improves Outlook performance, and makes the data easier to manage, search, and back up. Outlook performance can degrade significantly with oversized PST files.

What are the different ways I can split my PST file?

The SysCurve PST Splitter tool offers multiple options. You can split your file into smaller parts by a specific size (e.g., 2 GB each), by date range (e.g., one file per year), by specific folders, or by sender email ID.

Does this tool alter my original PST file?

No, the software works in a read-only mode. It reads your original large PST file and creates new, smaller PST files, leaving your original file completely untouched and safe.
