How to delete all build artifacts in TeamCity?

First, you need to configure a default clean-up rule. By default, everything is kept forever. Because of this, clean-up doesn't do much.

1. Go to the settings
2. Click on Clean-up Rules in the left navigation.
3. You may see multiple "build configuration or template", for each:
4. Click Edit.
5. Under "Clean Artifacts", choose custom policy.
6. Choose 1 days since last build or "1th" successful build, whichever makes the most sense to you.

All subprojects under will inherit this configuration. After this is configured, go to Administration > Server Administration > Clean-up Settings

The Previous clean-up section of the server clean-up settings enables you to:

• review the information on the previous server clean-up date and duration helping you decide whether to launch the clean-up process at a given moment
• run clean-up manually using the Start clean-up now button

During clean-up, TeamCity reports the progress. If you need, you can stop the clean-up process and the remaining data will be removed during the next clean-up.

Just press the button Start clean-up now
