Portable/USB saves files to local system

  • The USB/Portable versions 56.0.3051.99 and 57.0.3098.116 (probably earlier versions as well) save several files on the local computer's user profile. If this access is blocked, Opera presents error messages and/or crashes without notice. These files/locations must be allowed within the user profile:

    Expected result:
    These temporary files should be written to the opera cache directory under:

    Running on Windows 10 (multiple versions) using the launcher:
    launcher.exe --disable-update
    opera.exe --disable-update --ran-launcher --started-from-shortcut
    Note: I modified the launcher shortcut to disable auto-updates of Opera, but the files above are still written to the local disk.

  • What about Opera 58, the latest stable one?

  • There are a couple temp dir changes in the 59 changelog. One at least has something to do with a standalone installation. So, you might want to test 59 also.
