# ERR\_FSPROVIDER\_CANNOT\_CREATE\_FOLDER\_ON\_DIRECTORY\_UNAWARE\_FS: Cannot create a folder on this type of file system[¶](https://doc.dataiku.com/dss/latest/troubleshooting/errors/ERR_FSPROVIDER_CANNOT_CREATE_FOLDER_ON_DIRECTORY_UNAWARE_FS.html#err-fsprovider-cannot-create-folder-on-directory-unaware-fs-cannot-create-a-folder-on-this-type-of-file-system "Permalink to this headline")

You are trying to create an empty folder on a system that does not support it.

For example, S3 is not an actual file system. It identifies objects with keys, which may or may not look like a path on a file system. You can have a single object with key `a/b/c.txt`, which will be presented by many tools, DSS included, as a folder `a`, containing a folder `b`, containing a file `c.txt`. But them, you cannot have an empty folder `e/f/`, you need an actual file `e/f/g.txt` that will get prensented as a folder `e/f`.
