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.
1 Answer
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
Outputs:
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.
