Created attachment 4673 A .desktop file of Xfmedia I am using Xfmedia which has two .desktop actions included. [Desktop Entry] ... Name=Xfmedia Comment=Lightweight Media Player Exec=xfmedia %F ... Actions=Enqueue;Enqueue and Play; [Desktop Action Enqueue] Exec=xfmedia-remote -a %f Name=Enqueue in Xfmedia [Desktop Action Enqueue and Play] Exec=xfmedia-remote -p -a %f Name=Enqueue and play with Xfmedia While lower-case indicates of selections of one item, upper-case indicates of selection of multiple items. %f the path of the first selected file %F the paths to all selected files Thunar does not distinguish cases. According to the desktop file of Xfmedia, on selection of several files, only Open with "Xfmedia" should appear and the robust action entries "Enqueue in Xfmedia" and "Enqueue and play with Xfmedia" should not. This is exactly how the appearance of actions managed in Custom Actions is occurring as there is a segregation for %f and %F for Custom Actions.
I forgot to mention that Send To DOES respect %f and entries with %f will not appear in the Send To menu for selection of several files. Example: [Desktop Entry] Type=Application Version=1.0 Encoding=UTF-8 Name=Bluetooth Device Icon=blueman Exec=blueman-sendto %f
It is also allowed to spawn the command > 1 with %f.
Here is a related issue in which a developer confused %u with %U and, as a result, if one tries to open several files, the files will be opened in different instances instead of one (embarrassing) <https://mail.gna.org/public/whaawmp-dev/2011-11/msg00027.html> (this is about to be corrected, soon <https://mail.gna.org/public/whaawmp-dev/2012-10/msg00007.html>). So if one intends to add a .desktop action for *a file* to software, the users should have this action appear for a selection of one file only, otherwise, bad results may occur. > It is also allowed to spawn the command > 1 with %f. a. Send To or context-menu actions? b. By writing "the command > 1 with %f", did you meant to the situation I presented at the top of my comment? (that I am writing "now")

Code: %f ; Description: A single file name, even if multiple files are selected. The system reading the desktop entry should recognize that the program in question cannot handle multiple file arguments, and it should probably spawn and execute multiple copies of a program for each selected file if the program is not able to handle additional file arguments.
