Microsoft Teams: Files App Updating to OneDrive App Experience in Teams
The Files app accessed from the left side of the Teams desktop client will be updated with the new OneDrive app experience, bringing performance improvements, more views and the latest features of OneDrive to both classic and new Teams. All existing features of the Files app will also be available via this new OneDrive app experience.
As part of this change, the Files app will also become the OneDrive app. There is no change in the name of Files app in either classic Teams desktop client or Teams mobile client.
