I was successful in mapping a drive between PDF Expert on my device and my desktop so as to transfer files from the Desktop to my iPad device. I had never done this before. I was able to copy/transfer entire folders with multiple files over much faster than I could ever do so via email, etc.
Can anyone help me as to whether this same type of drive-mapping ... file transfer can be done in any of the other apps on the device such as GoodReader, iBooks and etc.
In PDF Expert, the device give you I guess what is called the ip address at bottom-left of the screen.
