What is the JTP file format?
.jtp is a template file format native to Windows Journal, Microsoft's stylus-and-handwriting note application that shipped with Windows XP Tablet PC Edition. Windows Journal was a software tool for creating notes and drawings that supported handwriting input. The program saved created notes in .jnt files. Each note could have its own style, formatting, and layout; to standardize notes across a team or project, using templates is the most effective solution. A .jtp file defines the page stationery - background color or image, line or grid ruling, page size, and default pen and ink settings - that is applied when a new note is opened.
Uses of templates
A custom template file can be created by opening a new note and adding appropriate formatting and elements - for example, a header with a company name and logo, or a page style of your choosing. That note must then be saved as a .jtp file. The saved template can be used to create new notes with the custom formatting already applied; the completed note is then saved to a separate .jnt file.
.jtp files share the same binary container family as .jnt notes and carry the MIME type application/vnd.ms-journal. Windows Journal was removed from Windows beginning with Windows 10 following a Microsoft security advisory; Microsoft OneNote is now the recommended replacement for digital handwritten notes.
Security & safety
RISK: MEDIUMWindows Journal was REMOVED by Microsoft specifically because of a security vulnerability in how it parsed Journal files - a maliciously crafted .jnt/.jtp could be used to run code on older systems. So treat unexpected Journal files from untrusted sources with caution and do not install the retired legacy app just to open one. The safe path is to use OneNote going forward and, if you must read legacy content, do it in an isolated/VM environment. The .jtp itself is just a template, but the parser risk is the reason the whole feature was retired.
Format details
in a nutshellPrograms that open JTP files
Windows3 apps
Microsoft OneNote (replacement, not a direct opener)
Free Microsoft's recommended successor. It does NOT import .jtp/.jnt directly - use it for new note-taking; migrate old content via PDF from a legacy machine.
Windows Journal (legacy, removed)
Built-in Original app on Windows XP-7. Removed from modern Windows for security reasons; only usable on a legacy/VM system that still has it.
Windows Journal Viewer (legacy, retired)
Free Microsoft's standalone viewer for Journal files - itself now retired; historically the only way to view .jnt/.jtp without the full app. Technical details
