Deleting the current working directory can result in unrecoverable errors due to platform operating system behavior. Platforms with drives demand special caution, because they usually maintain a separate working directory for each drive. Changing the current working directory to another drive before deleting the old working directory will not necessarily prevent an error from occurring, because the current working directory associated with the original drive can remain unchanged. Instead, change the current working directory to the root of the drive containing the directory you want to delete.
