Dolphin filemanager from KDE. Nowadays I default to "compact" view without "preview" enabled. This is similar to "Icon" view, but the icons are small. Lot of files scrolls horizontal instead vertical.
- filenames in compact mode can be longer in one line, which is kind of similar to the look as "details" view, but are all displayed in a multiple rows instead one row
- preview disabled, because this is extremely fast, as I have ton of files that do not even have a preview image
That's my default. Occasionally I enable preview image and switch to bigger "icon" view when I look into images or videos. Or sometimes I enable "details" view when needed. In normal usage I don't need the details anyway.
