Hello anonymous user,

Thanks for the question and using MS Q&A platform.

synfs will be used as schema instead of part of mounted path.

Example assuming you trigger to mountname chepraadlsgen2.

• Access the data using local file API, the path format like: /synfs/{jobId}/mountname/{filename}
• Access the data using mounted path with mssparkutils fs API, the path will little difference and like: synfs:/{jobId}/mountname/{filename}

Hope this will help. Please let us know if any further queries.

Bit late to the party.

Use...

import glob

jobId = mssparkutils.env.getJobId()
print(glob.glob(f"/synfs/{jobId}/*"))

This will list any mount points in the Synapse file system for the current job.

['/synfs/149/mdl_dfs', '/synfs/149/mdl_blob', '/synfs/149/mdl']
