PacletUninstall["PeterBurbery/\
FunctionsFromTheFunctionRepositoryIWantToStore"]

and I got this error:PacletUninstall::nodelete: The paclet named PeterBurbery/FunctionsFromTheFunctionRepositoryIWantToStore at location C:\paclets\functions-from-the-function-repository-i-want-to-store cannot be uninstalled because it does not reside in the standard paclet repository.

How can I successfully uninstall the paclet? I tried PacletDirectoryUnload["C:\\paclets"]. I also moved the whole paclet to a new directory C:\paclets-backup\functions-from-the-function-repository-i-want-to-store. I also deleted all the files in the build folder at C:\paclets-backup\functions-from-the-function-repository-i-want-to-store\build
