- *
- * FileSystem roots: /{bucket}/
- *
- * Treatment of S3 objects: - If a key ends in "/" it's considered a directory
- * *and* a regular file. Otherwise, it's just a regular file. - It is legal for
- * a key "xyz" and "xyz/" to exist at the same time. The latter is treated as a
- * directory. - If a file "a/b/c" exists but there's no "a" or "a/b/", these are
- * considered "implicit" directories. They can be listed, traversed and deleted.
- *
- * Deviations from FileSystem provider API: - Deleting a file or directory
- * always succeeds, regardless of whether the file/directory existed before the
- * operation was issued i.e. Files.delete() and Files.deleteIfExists() are
- * equivalent.
- *
- *
- * Future versions of this provider might allow for a strict mode that mimics
