Yes, in many cases free PST Splitter tools can be more prone to causing data loss, especially if they lack advanced processing algorithms, proper error handling, or integrity verification features. Free tools often have problems like not being able to split files completely, not being able to handle large or corrupted PST files well, and not having a way to recover files if the process is stopped. This makes it more likely that you will miss emails, have a broken folder hierarchy, or have output files that are damaged. On top of that, a professional tool like DataVare Outlook PST Split  Tool uses secure splitting technology to keep the original PST file the same while splitting it into smaller parts. It keeps the folder structure, metadata, attachments, and email properties. It can safely split large PST files by size, date, folder, or year without losing any data. It also offers a free demo version that lets users try out the software and see how well it works before they buy it. This helps make sure that the splitting process is reliable and that users feel confident in it.
