The file or directory name of containerPath will be preserved in localDir For example, if the container has /aaa/zzz.txt, - CopyFromContainer(_, "/aaa", "~/test") will create "~/test/aaa/zzz.txt" - CopyFromContainer(_, "/aaa/zzz.txt", "~/test") will create "~/test/zzz.txt".

The provided input will be extracted into the container's containerPath directory.
