Large storage taken by Docker ext4 file

[Kyuho_Lee]

Hello,
Hope my question is not silly and helpful for others also.

Does any of you have an idea about the ext4 file?
which is located following directory, C:\Users\paul\AppData\Local\Docker\wsl\data

Currently, I have actively run WebODM with Lightning Node.
I subscribed to Lightning ODM because the storage of my device was not enough
And I just realized whenever I run the process, a large portion of SSD has been taken.

I found ext4 file itself takes 107GB, making my laptop so slow.
Is it usual for using Lightning WebODM? and if I delete this file, will there be any problem with running docker and Lightning WebODM?
By the way, although I use Lightning WebODM, I still need to run it in the desktop app for 2D map and 3D model viewer for my research.

I believe deleting that file would cause problems. I am still learning about disk space usage and cleanup myself, but I have had good luck with “webodm.sh down” to free up storage used by WebODM.

./webodm.sh stop
./webodm.sh down
./webodm.sh start

After stopping WSL, enable Hyper-V Manager in the Turn Windows Features On or Off dialog, then use the Edit Virtual Hard-disk menu item to compact it down to the minimum size necessary for all the data inside.

Similarly, you can use this GUI to shrink/expand the dynamic VHDX, as well.

Or, you can do it via PowerShell
