Hello! New KDE user (Plasma 5.9.4) and loving it!
I'm curious, is there a way to have Dolphin show previews for PDFs/Images by default, rather than making me press the "preview" button on every subfolder? I have thousands of folders for which I'd like to see previews of the contents right away, rather than after pressing the button.

Thanks

or (Ctrl + m will show/hide the menu bar)

3. Configuring Dolphin > The View Properties Dialog

The View Properties Dialog

The View Properties dialog can be used to quickly modify several view properties at once. This is done for the current folder, for the current folder including all subfolders, or even for all folders, depending on the choice made in the Apply View Properties To section.

If Use these view properties as default is enabled, the chosen view properties will also be used for all folders which do not have customized view properties yet.

Thank you so much! For some reason I wasn't subscribed to this thread, so i'm only replying now.

KDE Frameworks 5 thumbnailer plugin is the ffmpegthumbs : https://cgit.kde.org/ffmpegthumbs.git/

Do you have it installed ?


Some distributions use the wrong path for plugin libraries: https://bugs.launchpad.net/ubuntu/+sour ... ug/1574037

What is your distribution/version ?


------------EDIT--------------


Thumbnailer plugin + settings

1) The KDE applications can show a thumbnail for a file if there is a thumb creator plugin installed for the file type.
2) After installation the plugin need to be enabled. With the KDE Applications 17.12 the Dolphin is enabling the plugins by default: https://phabricator.kde.org/D7440

With the Dolphin 17.08.3:

Dolphin previews for files by default

K File Manager Development List - Turn on Dolphin icon previews by default: https://marc.info/?t=150325738000013&r=1&w=2

Phabricator - Turn on Dolphin icon previews by default: https://phabricator.kde.org/D7440
