# ERR\_FSPROVIDER\_ILLEGAL\_PATH: Illegal path for that file system[¶](https://doc.dataiku.com/dss/latest/troubleshooting/errors/ERR_FSPROVIDER_ILLEGAL_PATH.html#err-fsprovider-illegal-path-illegal-path-for-that-file-system "Permalink to this headline")

The specified path is not supported on that file system.

For example, `.` and `..` are not usable on an S3 file system. 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`. Having a `.` or `..` in a key will not work as on a Unix- or Windows-style file system and is therefore not supported.

## Remediation[¶](https://doc.dataiku.com/dss/latest/troubleshooting/errors/ERR_FSPROVIDER_ILLEGAL_PATH.html#remediation "Permalink to this headline")

Fix the faulty path. If that path was set at the connection level, you will need DSS administrator access to fix it.
