Terms Of Use
Use the app within its supported scope and review the included license notices.
Free Desktop Utility
Free File Split Join is provided as a free Windows desktop utility. Check the current supported scope and inspect results before relying on them.
Use Files And Settings You May Change
Keep the original file until the joined copy is verified and usable. Splitting does not encrypt private data. Store or transfer sensitive parts using your normal secure storage and transfer method.
Open-Source Components
Included components retain their own copyright, license and warranty notices. See Open Source for corresponding source and upstream project links. The modified interface is an independent product, not an endorsement by the upstream maintainers.
No Guaranteed Result
Keep the whole generated .parts folder: every numbered part, manifest.fsj.json and the .check integrity file where generated. This release rejoins sets created by this app, not arbitrary historical splitter formats. Splitting is not compression or encryption.
Optional Software Is Separate
An optional research invitation has its own visible Agree / Decline screen and policies. Declining it does not prevent using the free application.
