Folder thumbnails in Thunar

Tue, 13 Aug 2019 21:12:35 +0000

My favorite file manager is Thunar, but it hasn’t folder thumbnails by default.

Here’s how to enable it.

Install tumbler and imagemagick

1yay -S tumbler imagemagick

Create the following a folder.thumbnailer file and add the following

1sudo vi /usr/share/thumbnailers/folder.thumbnailer

1[Thumbnailer Entry]
2Version=1.0
3Encoding=UTF-8
4Type=X-Thumbnailer
5Name=Folder Thumbnailer
6MimeType=inode/directory;
7Exec=/usr/bin/folder-thumbnailer %s %i %o %u

Create the folder-thumbnailer script

1sudo vi /usr/bin/folder-thumbnailer

 1#!/bin/bash
 2
 3convert -thumbnail "$1" "$2/folder.jpg" "$3" 1>/dev/null 2>&1 ||\
 4convert -thumbnail "$1" "$2/.folder.jpg" "$3" 1>/dev/null 2>&1 ||\
 5convert -thumbnail "$1" "$2/folder.png" "$3" 1>/dev/null 2>&1 ||\
 6convert -thumbnail "$1" "$2/cover.jpg" "$3" 1>/dev/null 2>&1 ||\
 7rm -f "$HOME/.cache/thumbnails/normal/$(echo -n "$4" | md5sum | cut -d " " -f1).png" ||\
 8rm -f "$HOME/.thumbnails/normal/$(echo -n "$4" | md5sum | cut -d " " -f1).png" ||\
 9rm -f "$HOME/.cache/thumbnails/large/$(echo -n "$4" | md5sum | cut -d " " -f1).png" ||\
10rm -f "$HOME/.thumbnails/large/$(echo -n "$4" | md5sum | cut -d " " -f1).png" ||\
11exit 1

1sudo chmod +x /usr/bin/folder-thumbnailer

To add a thumbnail to a folder you just need to add a .folder.jpg file and your set. You can decide to use different names in the /usr/bin/folder-thumbnailer script.
