With Windows 8, Metro Style Apps File Picker is not able to see any files inside a virtual drive. Is there a way around this issue or is this behavior mentioned from the sandbox inside the Metro Style Apps are working?

kind regards,

Thank you for contacting us.

What version of CBFS are you using? Support for Metro applications requires handling of new IRPs, and this handling was added in CBFS 4.

Sincerely yours

Yes, I am using CBFS 4. The funny thing is, that Metro Apps are able to read files directly (for example i can open images linked to a Metro App), but the file picker is not able to "scan" the directory (-> the virtual disk is just empty).

kind regards

One of the customer has reported quite a similar problem with Metro Style Apps File Picker and the use of a mounting point with the CBFS_SYMLINK_MOUNT_MANAGER helped. Of course we are going to investigate and correct it, but it hasn't been done yet.

Let's continue the discussion in the helpdesk.
