I do not see them in the /clockworkmod folder when I connect my device to my PC. I tried using adb pull but adb does not show any devices when the device is in recovery mode (only if it's booted).
Version is 4.2.1; ROM Cyanogen. Device is MAKO, and my PC is running Windows 7. The drivers for the device have already been added/installed from the android-sdk extras folder. The folders I see when I connect the device to win7 are different than those I see when I browse on the device itself.
This issue might pertain to the way 4.2.1/4.2.2 creates folders (something about multi-user).
