sony-camera-api - CameraRemoteAPIbeta - deleteContent/actFormatStorage

In the reference guide of the Sony Camera Remote API SDK (Sony_CameraRemoteAPIbeta_API-Reference_v2.10.pdf) the methods deleteContent and getContentList are documented.

But using the Sony Camera Remote API SDK with a Sony QX1 the methods deleteContent and getContentList are not listed in the results of getAvailableApiList (neither in "Remote Shooting" nor "Contents Transfer" mode).

I assume that they are therefore not available?

How can the photos on the SD card be deleted or formatted?

Running getAvailableApiList does list actFormatStorage in "Remote Shooting" Mode. How can this be applied?

I have been able to delete files from the camera using the following sequence of calls:

• setCameraFunction to "Contents Transfer"
• getSourceList to get storage location
• getContentCount to get count of files
• getContentList to get list of files on camera
• parse content list to get file URI's
• deleteContent to delete each file

I am also trying to figure out how to use the actFormatStorage, but no luck so far
