# PST Compress Tool Discussions

The DRS Softech PST Compress Tool is a Windows-based utility designed to reduce the size of Microsoft Outlook PST files. It enables users to compress multiple PST files simultaneously, using various compression modes such as removing or extracting attachments. The tool supports both ANSI and UNICODE PST formats and provides options for filtering emails by date, previewing content before compression, and removing duplicate messages. Users can also split large PST files and apply password protection to the output files. It functions independently of Outlook and is compatible with all major Windows operating systems.
