Might be better to name this MTPFileUtil (and use kFileSystemTypeMTP)?

[kmadhusu, 2012/07/27 02:13:40]

As we discussed, I am going with DeviceMediaFileUtil. I am planning to use this
util for both mtp and ptp devices. So, I am not sure if we need
'kFileSystemTypeMTP' type. I would like to call it as
'kFileSystemTypeDeviceMedia' for device media and for local media we can call it
as 'kFileSystemTypeLocalMedia'

This needs to be in private:

Done.
