Bug ID: 414068
Summary: Dolphin/dialogs should cache folder contents instead
of repopulating the folder view every time.
Product: dolphin
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: dolphin-bugs-n...@kde.org
Reporter: nervecent...@gmail.com
CC: kfm-de...@kde.org
Target Milestone: ---
SUMMARY
Whenever browsing to a large folder with Dolphin or a save dialog, the contents
must be repopulated fresh each time. Clicking before the refresh is finished
can lead to browsing into the wrong folder or accidentally clicking a file as
contents fill in. Having to wait slows down browsing immensely and likely
thrashes the hard drive.
Dolphin/KDE should have an in-memory cache which is as simple (and thus small)
as possible, which stores the highest sorted (and thus visible) contents of
commonly browsed folders, such that file browsing is as instantaneous and
smooth as possible. Thumbnails could also be stored if the space to store them
is not an issue.
STEPS TO REPRODUCE
1. Find a large folder with many files.
2. Browse to it in Dolphin.
OBSERVED RESULT
Folders and files take several seconds to repopulate and fill the view, most
noticeable on hard drives.
EXPECTED RESULT
The highest-sorted folder contents should already be present and visible. This
behavior is best-represented by Windows' file manager.
