In Nexus 3.83 the blob store structure moved from volume and chapter based to date based. The `2025` directory is part of Nexus Repository’s **new, date‑based blob store layout** , which was introduced as an alternative to the older `vol-XX/chap-YY` layout. In this new layout, blobs are stored under a path like: `/content/YYYY/MM/DD/hh/mm/` So no, these cannot and should not be deleted. That will result in data loss. The old vol/chap structure remains for any deployments that used the previous structure and before the new one was introduced. Do not delete either of these directories. If you are looking to save space then you should leverage [cleanup policies](https://help.sonatype.com/en/cleanup-policies.html) and the [compact blob store](https://help.sonatype.com/en/tasks.html#UUID-53669de9-914f-58da-0ba3-9e129cd2e3de_id_Tasks-Admin-Compactblobstore) task. --- _[View the full topic](https://community.sonatype.com/t/dates-in-blob-files/16031)._
