# Manage the Extension
*(Sub‑section of: Process Designer Reference → Process Designer Component → Custom Extensions)*
ONEWEB provides an **Extension Store** to manage all installed Custom Extensions within an application.\
This store allows users to **enable, disable, or remove extensions** without rebuilding or reinstalling them.
Managing extensions centrally helps maintain clean process environments and prevents unused or obsolete extensions from affecting workflows.
***
### Accessing the Extension Store
To manage extensions in an application:
1. Open **Process Designer**
2. Click the **Extensions** icon 
3. Select **Store Extension**
The **Extension Store** page will be displayed.
***
### Managing Installed Extensions
Within the Extension Store, users can perform the following actions for each installed extension:
#### Enable / Disable Extension
* Enable an extension to make it available in Process Designer
* Disable an extension to temporarily hide and prevent its use in workflows
* Disabling an extension does **not** remove it from the application
#### Delete Extension
* Remove an extension completely from the application
* Deleted extensions are no longer available for use
* Any process using the deleted extension must be reviewed before execution
After making changes, click the **Save** button to apply updates to the application.
***
### Important Considerations
* Disabling an extension does not alter existing process definitions but may affect execution
* Deleting an extension that is referenced in a process can cause validation or runtime errors
* Always review processes after enabling, disabling, or deleting extensions
* Use version control strategies when replacing or updating extensions
***
### Best Practices
* Disable extensions that are no longer required instead of immediately deleting them
* Keep only production‑ready extensions enabled
* Use meaningful naming and versioning for extensions
* Periodically review the Extension Store to keep the application clean
* Validate processes after any extension changes
***
### Summary
The **Extension Store** provides centralized control over all Custom Extensions in an application.
Key capabilities:
* Enable or disable extensions without reinstalling
* Delete unwanted extensions
* Control availability of custom activity nodes
* Maintain a clean and manageable process environment
Using the Extension Store effectively ensures that **Process Designer workflows remain stable, maintainable, and aligned with application needs**.
