# Supported File Formats

Coresee can natively present a defined set of file formats directly inside a room — no screen share required. Files outside this set can be uploaded and stored, but cannot be presented to participants.

## **Unsupported Formats**

Some file formats cannot be presented natively in a Coresee room. Files in these formats can still be uploaded to the Files tab for sharing purposes.

### **How to identify an unsupported file**

You don't need to check the format manually. Coresee surfaces two clear indicators:

* **Warning on the thumbnail** — unsupported files display a warning indicator directly on their thumbnail in the Files tab, visible before you attempt to present.
* **Present button greyed out** — when you open the file's context menu, the Present option is disabled and cannot be selected.
