Mime types under Linux
Accroding to this post do (this is an almost excact cite of the post!):
All you need to associate file of some type to be handled by some app, also by wine app, you can find in folder
you will need to open
Locate the section [Default Applications] or [Added Associations]
and find needed type, like this:
as you see there are two files which are relative to this type, if the file stand first it will be the default handler for this type, the other will be shown in "Open with" menu
this is example of .desktop file
[Desktop Entry] Name=PHP Expert Editor Exec=wine start C:\\\\Program\\ Files\\\\PHP\\ Expert\\ Editor\\ 4.3\\\\phpxedit.exe z:%f MimeType=image/jpeg Type=Application StartupNotify=true Path=/home/m/.wine/dosdevices/c:/Program Files/PHP Expert Editor 4.3 Icon=/home/m/.local/share/icons/10de_phpxedit.0.png
the whole point in the "Exec=" line at the and "z:%f"
Exec=wine start C:\\\\Program\\ Files\\\\PHP\\ Expert\\ Editor\\ 4.3\\\\phpxedit.exe z:%f
if you don't have this line you should have an error
Can not open file "/home/...."
while trying to open some file with your app, because of wine paths are like windows disks and to open your file, for example "/home/picture.jpg" in wine you should use path "z:/home/picture.jpg"
$> man xdg-mime xdg-mime - command line tool for querying information about file type handling and adding descriptions for new file types [...]
$> man xdg-open xdg-open - opens a file or URL in the user's preferred application [...]
You can open any file with the desired program and the xdg-open command:
$> xdg-open special_file.pdf
Setting the default type is easy:
$> xdg-mime query default application/pdf AdobeReader.desktop $> xdg-mime default kde-kpdf.desktop application/pdf $> xdg-mime query default application/pdf kde-kpdf.desktop
