# Exceptions for Incremental Files

The following information only applies to Incremental Direct Data files.

## Transaction Times & Data for Incremental Files {#transaction-times--data-for-incremental-files}

With the availability of Incremental files with Direct Data API, Vault has a consistent way to capture and report on data changes that are committed to the database in 15-minute increments. This ensures that Direct Data API provides a fully consistent data state based on the committed data.

However, Incremental files only include Vault events that are committed to the database within a given time frame. The database commit time may differ from the last modified time. The last modified time may be updated by long-running transactions such as jobs, cascading state changes, or even triggers that create additional entities as part of an SDK job.

## User Logins in Incremental Files {#user-logins-in-incremental-files}

Direct Data API captures user logins as events within the `user__sys.csv` extract file even if no additional changes were made to the *User* object record, including if the record's `modified_date__v` value remains unchanged.
