Hello Joby,

These files are part of MongoDB’s underlying WiredTiger storage engine, and each has a specific purpose.

  • WiredTiger.wt: Yes, this does store actual user data. It’s the main data file where WiredTiger stores table content , which includes your collections and indexes. It’s essentially the physical representation of your logical data.

  • WiredTiger.turtle: This one is different , it’s more like a metadata/config file. It contains the schema-level configuration for the WiredTiger engine (like table settings, checkpoint info, etc.).
