Original GitHub issue: https://github.com/ollama/ollama/issues/9097

I have just uninstalled Ollama (I think it was 0.5.7) under Windows in order to perform a clean reinstallation. Unfortunately, I found that all model files in .ollama were deleted without being asked. I did not expect this. Please add a checkbox / confirmation to the uninstall program, e.g. “Do you want to remove the model files?”

Howdy, yes what a great idea. srry about that, happened to me also. I have been saving a backup of the .ollama folder before uninstalling or anything like that, and replacing the fresh with the backup (but I did learn the hard way), but if you don't know, then you don't know, so yep, a prompt or something would be great.

so far, I have tested this functionality and the functionality works.

I'm simply used to the behavior under Linux with a package manager - if there are no additional post-installation scripts, only the files that were present at the time of installation are cleaned up.

You're right about backing up the complete folder - it affects all user data in %USERPROFILE%\.ollama (e.g. also the prompt history) as well as %USERPROFILE%\AppData\Local\Ollama (server logs etc.) - not just the model files as initially stated.

I believe it is common for some other programs such as VLC to ask whether the user preferences should also be removed when uninstalling under Windows.
