Hello, No issues here just needing some insights on filesystem storage ... I just moved to it (on 4.3-milestone-1), and ran script to migrate my attachments from db to filesystem. Though attachments seem to open perfectly well, I'm surprised by the difference in size: file "xwikiattachment_content.MYD" (I'm using MySql as you guess) is about 1,3GB, while my whole folder ${xwiki.data.dir}/storage is only about 600MB. What could explain such a big difference ? (apart from some attachments that may not have been migrated) Considering: "It is prudent to leave the attachments in the database since in most situations the attachment data is not bothersome just sitting in the database (The only risk of attachments left in the database is that they will bloat the size of the database files)" [1] Ok with that, but supposing that I checked my attachments are ok and I'm satisfied with fs storage (or I'm just using a test xwiki that I can blow away without risk), removing attachments from db means cleaning table xwikiattachment_content, is it right ? Can I remove other xwikiattachment* tables, or are they still used to reference the attachments ? (I guess they do but...)
