Extension of Protonized Files

Until now Prot-On kept the extension of files when protect them, thus e.g. a file named example.pdf was protected as example.proton.pdf

Now, by default the extension will change to a specific Prot-On extension, so the file example.pdf will be protected as example.proton-pdf

Reason for this change is that it allows to associate in the operative system the extensions proton-* to Prot-On application, what improves the user experience:

  • Double-clic opens the file with Prot-On without a competition with other applications, as the extension is owned by Prot-On exclusively.
  • File icons are better identified as protonized files, because Prot-On uses its own icons instead overlaying a small icon over the original, which could compete with other applications trying to do the same (i.e. storage synchronization tools like Dropbox).
  • If the user tries to open a protected file with other application, this one will not modify the file content as it does not recognize the format, avoiding a potential problem of corruption of files.

Counterpart is that a user without Prot-On installed is not able to open the file and then the template indicating that it is a protected file will not be shown any more.

The domain administrators who prefer to maintain extensions can configure it in the domain settings.
