Diskvu

Diskvu is a Qt-based Linux desktop application for exploring disk usage as an interactive treemap.

Features

• Interactive treemap navigation with free zoom, breadcrumb and tree navigation
• Background refresh and filesystem watching for the active tree
• Search and filter by name, size, date and custom folder marks
• Optional image and video thumbnail generation
• File-type list with aggregate size and item counts
• Customisable themes, file colors, and automatic dark mode switching

Requirements

• CMake 3.21 or newer
• A C++17 compiler
• Qt 6 development packages with:
  • Core
  • Gui
  • Widgets
  • Concurrent
  • Svg
  • LinguistTools
  • Test (for the test suite only)

Debian/Ubuntu:

sudo apt install cmake g++ \
    qt6-base-dev qt6-svg-dev \
    qt6-tools-dev qt6-l10n-tools

Arch Linux:

sudo pacman -S cmake qt6-base qt6-svg qt6-tools

Fedora:

sudo dnf install cmake gcc-c++ \
    qt6-qtbase-devel qt6-qtsvg-devel \
    qt6-qttools-devel qt6-linguist

macOS (Homebrew):

brew install cmake qt6

Build

Configure and build with CMake:

cmake -S . -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build --target diskvu -j$(nproc)

On macOS, point CMake at your Qt6 installation first:

cmake -S . -B build -DCMAKE_BUILD_TYPE=Release \
  -DCMAKE_PREFIX_PATH=$(brew --prefix qt6)
cmake --build build --target diskvu -j$(sysctl -n hw.ncpu)

The main app target is produced as diskvu:

./build/diskvu
./build/Diskvu.app   # (macOS)

macOS and Windows builds are currently unsupported but fully functional.

Install

Install system-wide after building:

sudo cmake --install build

Or install to a custom prefix:

cmake --install build --prefix ~/.local

Uninstall with:

sudo cmake --build build --target uninstall
