Cool, thanks for your contribution, @HardCodeDev777 ! Clean style and formatting!

I tested it and I believe it currently deletes a bit "too much". For example:

.gitignore
.sln.DotSettings (checked into git to share with team)
local ignored auth file (need to keep)
local ignored packages (not shared with team, e.g. special designer tool)
BuildPipeline folder (e.g. Jenkins scripts in project root)
...

It's similar to the git command which deletes all untracked files:

git glean -fd

Since that already exists, we don't need to provide this specific functionality in UCLL.

Let me propose inverting the logic:

• Search for known Unity directories to delete: Library, obj, Logs, Temp, UserSettings (because window layout is one of the things that can corrupt, probably other user settings from packages as well)
• Search for known Unity-generated files in project root: .sln, .csproj, .user (e.g. .sln.DotSettings.user)

Basically, we want to get rid of things that can corrupt project state and which users would sometimes manually delete to fix issues. I consider all user settings to fall into this category.

We can assume that most users will be using version control, so they can always use their vcs to delete everything untracked, but for UCLL it makes most sense to focus on specific Unity file system entries.

If you agree, please go ahead and implement the changes, I'll help you test (I have quite a few large-scale company projects that I can use). And thanks again! :)

Thanks for feedback!

I thought about this way of implementation, but I wasn't sure if only Library, obj, Logs, Temp, UserSettings, .vs, .idea and .sln, .csproj, .user files - maybe for other IDEs or OS there're will be another cache files, so I chose the easiest and 100% working way. Also I didn't know about git glean -fd command😁

But I agree, it makes more sense and I'll rework it accordingly👍

I’ve updated the implementation and also added --keep-user-settings flag.

Thanks, I tested it and it works nicely. Let me do a few tiny formatting changes and also add a few more file extensions that I know about like .utmp, mono_crash*, and InitTestScene*. And then I'll merge.
