Hi Ujval Gandhi ,

Welcome to the Microsoft Q&A and thank you for posting your questions here.
You can make Purview list every file as its own asset (not a resource set) by creating a Resource-set Pattern Rule with “Do not group as resource set” turned on.

Steps

• Purview → Data Map → Source management → Pattern rules → New.
• Choose the source type, pick your storage account, and scope it to the container/folder that holds your files.
• New rule → set:
  • Rule name (anything)
  • Qualified name = a pattern that matches your file paths
  • (Optional) Display name template
  • Enable “Do not group as resource set”
• Save the rule and run a scan. New scans honor the rule; existing assets update over time.

Example (per-file cataloging) If your paths look like:
https://<acct>.blob.core.windows.net/raw/machine-89/2025-01-01/22-33-22-001.avro use a rule under the raw scope with a Qualified name like:
machine-{{machineid:int}}/{{:date}}/{{:time}}-{{:int}}.avro and
keep “Do not group as resource set” = On.
You’ll get one Purview asset per file.
