HTML5 FileSystem: How to revoke granted quota?

Question

I use window.webkitStorageInfo.requestQuota() to get disk quota. Everything works as it should but I can't revoke already granted quota for debug purposes. Seems there is no API for that. And more over I can't find how it can be done through Chrome interface. I've found this link: chrome://quota-internals/ but it just provides a read only info. I am developing chrome extension and even uninstalling/installing of it doesn't help. Who knows how to reset local disk storage settings for the site (or extension) or even the storage as a whole?

Answer 1

1. Go to: chrome://settings/content
2. Under cookies click: All Cookies and Site Data
3. Filter down to the host you want to revoke access for
4. Click through the permissions (filesystem, database, cookie, etc.) you want to remove.
