Source 2 Viewer v9.2

Opens large VPK archives up to 8 times faster with a third of the memory, and adds previews of files right inside the package viewer.

Optimized package viewer

The file tree is now created lazily, which vastly improves performance and memory usage on large VPKs.
For example, the Dota 2 pak01_dir.vpk contains 325k files (which also create 40k folders).

This VPK now opens 8 times faster, and consumes 3 times less memory.
This also makes closing the tab much faster as it no longer needs dispose every single tree node.

File previews

There is now a setting to preview files right from the package viewer,
including an option to autoplay sounds.

Selecting a file in the tree view will automatically load it in the right pane,
and selecting a folder will show the folder contents as it did before.

This may be slow for certain big files like models with many animations.
Preview-on-click feature can be enabled in settings.
