Description Huzaifa S. Sidhpurwala 2017-04-19 06:25:23 UTC 
A mechanism to bypass file system access protections in the sandbox to use the file picker to access different files than those selected in the file picker through the use of relative paths. This allows for read only access to the local file system.
