I have file with extension ".application" which I want to open, but I don't know how.. :/ I do have PlayOnLinux if it can help me in this case.


I couldn't find anything specific about how to launch these Microsoft 'ClickOnce' files with PlayOnLinux. However, there is a Wine FAQ on it which suggests:

wine start whatever.application

PlayOnLinux uses wine so you should already have it installed. You may also need to use winetricks to install the version of .NET required by the application.

Winetricks Installation

cd "${HOME}/Downloads"
wget https://raw.githubusercontent.com/Winetricks/winetricks/master/src/winetricks
chmod +x winetricks

Installing .NET (4.0) with winetricks example

bash winetricks dotnet40

Edit: Finding out about unknown extensions

If in future you have a file with an unknown extension (or no extension at all) the file command can tell you about the file:

file a-jpeg-file-with-wrong-ext.txt


a-jpeg-file-with-wrong-ext.txt: JPEG image data, JFIF standard 1.01 etc

Additionally, you can look up extensions online. A good database for this is fileinfo.com.
