FileSystem dock won't show any file / folders, and has performance issues when loading large folders

[FaerDerr]

Tested versions

Tested in 4.2.2 stable, 4.3 beta 5, 4.3 beta 6.

System information

Godot v4.2.2.stable - Windows 10.0.19045 - Vulkan (Forward+) - dedicated NVIDIA GeForce RTX 2060 (NVIDIA; 31.0.15.5186) - AMD Ryzen 5 3600 6-Core Processor (12 Threads)

Issue description

I tried loading this sprite database : https://github.com/PMDCollab/SpriteCollab/tree/master/sprite It's around ~1Go of .png (1025 pokemons + shinies, all in pixel art), saved in 1025 folders.

Here's the exhaustive list of what I encountered while trying to import that across three versions:

• It took any version tested 10+ minutes to import everything
• IF the import is successful, I need to Alt+F4 / task manager to exit godot
• While open, the editor seems to run fine. I can create empty new scenes, save, load and play them.
• I don't see any file nor folder in the FileSystem Dock, but I see them using the load window.

• Reloading the whole project fixes this last issue, but takes 10+ minutes of reimport and I need to do that every time I open godot.
• Alternatively, creating a folder will trigger a scan (taking again ~10min) and it will fix the problem, until you need to close / reopen the engine

• When the issue is fixed after reimporting, the filesystem dock will lag & jitter, making it hard to use

Expected behaviour :

• Load the big folder (takes some time to import, but should be less than 10 minutes)
• After import, all the files can be seen in the filesystem dock without decreased performance
• We can close the engine whithout relying on task manager

Steps to reproduce

• Create an empty project
• Try to import the sprite folder from provided link : https://github.com/PMDCollab/SpriteCollab/tree/master/sprite
• If successful, either godot will crash, or you won't be able to see the folder architecture after import
• If that's not the case, close godot and reopen it : all the folders should be gone from the filesystem dock

Minimal reproduction project (MRP)

I can't upload the project here, as it weight too much. It's an empty project with just the mentioned file above, no scripts, no editor settings, no scenes.

• When the issue is fixed after reimporting, the filesystem dock will lag & jitter, making it hard to use

This is because the entire list of files is displayed at once in the FileSystem dock. Without manual pagination or controls suited for displaying large lists, this can't be fixed.

Probably the same as https://github.com/godotengine/godot/issues/47053 (at least the part about filesystem not showing up for a long time)

Probably the same as #47053 (at least the part about filesystem not showing up for a long time)

I saw this one but the topic and bug seems to be targeted at godot 3.x versions, I didn't saw any issue report for 4.x versions !

I think calinou has the right call here : I'm pretty sure most of these issues could be fixed if #9678 is implemented.

Not for the import part, but a faster FileSystem might be the way. Having an option to not show the content of certain folders while still importing their contents might be an "easy" temporary fix

Duplicate of #47053 (reopened as #92650 was reverted for 4.3).
