If you have called collection.insert() and the data has been flushed to disk, you will see "insert_log", vectors and scalar data is stored here.
"stats_log" stores the statistical information of segments, including bloom filters.
If you have called collection.create_index(), you will see "index_files", index is stored here.
If you have called collection.delete(), you will see "delta_log", this folder stores the primary key of deleted entities.

what means the number as marked,such as "451860017338870801"

[yhmo]

/insert_log/[collection ID]/[partition ID]/[segment ID]/[field ID]
/stats_log/[collection ID]/[partition ID]/[segment ID]/[field ID]

how can i find the "collection ID" about a collection?

[yhmo]

Collection/partition/segment ID is for internal usage, users no need to know them.
You can use print(collection.describe()) to print the detailed information of a collection, including its ID. But in pymilvus there are no interfaces to know a partition's id and a segment's ID.
