I have some rar files that might contain malware. I want to check the contents in windows sandbox. I am pretty new to this and dont know how I can do this without needing to install winrar every time just to open the contents of a rar file.

    Hi wadid,

    I'm Rodrigo and I'll help you.

    Windows 10 does not natively read .rar files, you will always need third-party software to be able to open these files in Sandbox mode. A good option is to keep a portable version of 7-zip (which can open .rar files too), copy to the Sandbox and use it to open the .rar files, without installing anything.

    Download 7-zip portable here:

    https://download2.portableapps.com/portableapps...

    The Installer will only extract the files to a folder, copy the 7-zip folder to the Sandbox to use it.

    Yes, I missed this detail, I think some adjustments in the code should do the work. Looks like the project is active, you can make a pull request to implement this.,

    I did find this project: https://github.com/damienvanrobaeys/Run-in-Sandbox But testing it I found out that winrar rar archives dont work (you dont get offered a context menu for winrar files somehow). winrar.zip and 7zip.rar seems to work (I could only test zip not 7zip.rar).

    Thats a bit a pitty as the project seems pretty helpful. But I dont have a clue what needs to be altered in code.

    Well, I tried to use a Sandbox configuration file and winget command to automatically install 7-zip but looks like Sandbox does not support Winget commands.

    Cool thank you! A more automated way would work with scripting I guess?
