Talk:Cinnamon Desktop
like this:
[MIME Cache] inode/directory=qiv-usercreated-0.desktop
in ~/.local/share/applications, and a qiv.desktop in the very same folder. For record, for my qiv, this gives me:
[Desktop Entry] Encoding=UTF-8 Name=Sildeshow (random, recursive) Exec=qiv -Rrlfstmiu MimeType=image/jpeg Icon=exec NoDisplay=false
Another example:
/home/photos/.local/share/applications/mimeinfo.cache
[MIME Cache] inode/directory=lazyslideshow-usercreated-0.desktop;qiv-usercreated-0.desktop application/x-shellscript=sh-usercreated-0.desktop text/plain=leafpad-usercreated-0.desktop
.desktop files
lazyslideshow-usercreated-0.desktop qiv-usercreated-0.desktop

You can start by right clicking an item, then click Open with ..., and choose "Custom Command Line" (instead of the picking from the normal list). Here you have to add an "Application name". Now there will be a file in /home/pi/.local/share/applications
PCManFM can be extended via custom actions
PCManFM can be extended via “custom actions”, which, on the appropriate cases, can be accessed in the context menu of the application. They are quite easy to write, since they follow the Desktop Entry Specification. Custom actions, and the conditions for their applications (e.g. on what files they should be applied, for example) are defined in files with the .desktop extension, placed under the ~/.local/share/file-manager/actions directory.
