KDiskFree review
A free graphical view of mounted-device capacity, with no folder-level usage scan.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
KDiskFree is a KDE desktop utility for Linux users who need a quick graphical view of mounted storage. It lists mounted file devices and mount points, then shows each device's capacity, used space, free space, and filesystem type. The interface also supports opening a selected device in a file manager. Its focus is device-level visibility, making it suitable for checking mounted volumes rather than investigating which folders or file types consume space.
The utility's standout strength is a compact overview of mounted devices and their filesystem information in one place. Users can see capacity and availability without navigating through individual directories, while mount and unmount actions add basic device-management capability when permissions allow. Opening a selected device in a file manager provides a direct path from overview to browsing. As free, open-source software for KDE/Linux desktops, it fits organizations and individuals that prefer an openly distributed desktop utility; documentation and community channels provide the stated support options.
KDiskFree remains a narrow disk-space analyzer. It reports filesystem and device totals, but it does not provide folder-level treemaps, file-type analysis, or file-usage scanning. That limitation matters for anyone trying to locate large directories or reclaim space by inspecting individual files. Linux users who want mounted-volume capacity checks can choose KDiskFree, while those needing detailed content analysis should select a tool designed for folder and file scanning instead. Mounting and unmounting are also conditional on system permissions, so those actions may not be available in every session.
