TL;DR

🩹 Fixed

  • Emails copied by other tools still preview as emails
Read more: everything in 2.4.1 ### Fixed - **An email that has been copied around now still previews as an email.** Some tools rewrite line endings when they copy a file, which doubles the invisible marker that separates an email's headers from its message. SageThumbs was strict about that marker, so a mail that had been through such a tool opened as raw source text instead of as a message. It now reads either form.

Portable (no installer)

Extract and run. Nothing is installed, nothing goes in the registry, no admin needed. Settings live in SageThumbs2K.ini next to the exe.

You get the app and the command line tool: settings, convert and resize, quick preview, screenshots, OCR, the colour picker and the folder tools.

Explorer thumbnails and the classic right-click menu work too. Turn them on with st2k register, or the button in Settings under Advanced. That registers the handler for your user account only: no installer, no administrator rights, nothing written machine-wide. st2k register --off undoes it, and you should run that before moving or deleting the folder, otherwise Windows is left pointing at a file that has gone.

Three things still need the installer, because Windows only accepts them registered for the whole machine: the Explorer preview pane, the Details pane columns, and the Windows 11 right-click menu (the compact one).
