+HOWTO: MAKE CUSTOM FOLDER ICONS
+
+Find some cool icons in /usr/share/icons/... and get to work!
+
+
+Tested in LM Xfce 19.3 we was on ubuntu 18.04 and on thunar 1.6.15.
+
+Now, that we are on LM 20 xfce and on thunar 1.8.14 ... we are able to show custom folder icons in thunar.
+(Might be useful for music-collections - or image-collections ... e.g.)
+
+As shown on the xfce4 website we will need two scripts to do it.
+
+I will show you the way i got it to work (without the use of terminal)
+
+1. open up thunar and create a folder in your home-directory and name it like "mythunarfiles" (without quotes) ... or whatever you want.
+
+2. open up xed and copy the first script to it :
+
+Code: Select all
+
+#!/bin/bash
+ 
+convert -thumbnail "$1" "$2/cover.jpg" "$3" 1>/dev/null 2>&1 ||\
+convert -thumbnail "$1" "$2/.icon.png" "$3" 1>/dev/null 2>&1 ||\
+rm -f "$HOME/.cache/thumbnails/normal/$(echo -n "$4" | md5sum | cut -d " " -f1).png" ||\
+rm -f "$HOME/.thumbnails/normal/$(echo -n "$4" | md5sum | cut -d " " -f1).png" ||\
+rm -f "$HOME/.cache/thumbnails/large/$(echo -n "$4" | md5sum | cut -d " " -f1).png" ||\
+rm -f "$HOME/.thumbnails/large/$(echo -n "$4" | md5sum | cut -d " " -f1).png" ||\
+exit 1
+
+3. save the script as :
+
+Code: Select all
+
+folder-thumbnailer 
+
+to the folder home/yourname/mythunarfiles
+
+4. now copy the second script to xed :
+
+Code: Select all
+
+[Thumbnailer Entry]
+Version=1.0
+Encoding=UTF-8
+Type=X-Thumbnailer
+Name=Folder Thumbnailer
+MimeType=inode/directory;
+Exec=/usr/bin/folder-thumbnailer %s %i %o %u
+
+5. save the script as :
+
+Code: Select all
+
+folder.thumbnailer 
+
+to the folder home/yourname/mythunarfiles
+
+Open up thunar and
+
+home/yourname/mythunarfiles
+
+Open up a new thunar window
+
+6. navigate to > filesystem > usr > bin
+
+7. make a right click on the folder and choose "open as root"
+
+8. Drag and drop the file
+
+Code: Select all
+
+folder-thumbnailer
+
+from the thunar-window home/yourname/mythunarfiles to the window /usr/bin (which is now opened with root-privilegues.)
+
+9. now do a right click on the file folder-thumbnailer (that now sits in /usr/bin/
+and choose > Properties> Access rights and mark: "File can be started as a program"
+
+10. close the Folder
+
+11. navigate to > filesystem > usr > share > thumbnailers.
+
+12. now do a right click on the folder and choose "open as root"
+
+12. Drag and drop the file
+
+Code: Select all
+
+folder.thumbnailer
+
+from the thunar-window home/yourname/mythunarfiles to the window /usr/share/thumbnailers (which is now opened with root-privilegues.)
+
+13. now do a right click on the folder.thumbnailer (that now sits in /usr/share/thumbnailers
+and choose > Properties> Access rights and mark: "File can be started as a program"
+
+14. close the folder.
+
+15. Very important :
+
+to get it to work : you must install imagemagick
+
+Code: Select all
+
+apt install imagemagick
+
+16. Now restart the system
+
+17. And now restarted :
+...... if you place a jpg-image with the name :
+   cover.jpg
+or
+   .icon.png
+into a folder ..... the folder icon will show it .
+
+And if you delete the file thunar will show the "normal" file icon again ...
