USB File Transfer is the fastest and the easiest way to put files to GoodReader from your computer. Unlike with WiFi File Transfer, there's no need to go through a complicated WiFi setup process, and a frustration of WiFi network troubleshooting.
Apple is providing a way to transfer files to applications via a USB cable in their iTunes computer program. You can find the directions below.
USB file transfer using Apple's iTunes computer program (iTunes File Sharing)
iPhone notice: GoodReader for iPhone needs to be updated to v.2.8 in order to be used with iTunes FIle Sharing. This update is in final stages of production and will be released very soon.
start iTunes on your computer (make sure that you have the latest version of iTunes)
connect your iPad / iPhone / iPod touch to your computer via USB cable
click on your device's name on the left pane of iTunes window
select the Apps tab on the right pane of iTunes window
scroll the window down till you find the File Sharing section
select GoodReader in the list of apps that support iTunes File Sharing
in GoodReader Documents window you will find documents stored in My Documents folder of GoodReader
drop your files to this window, and they will be immediately transferred to GoodReader
you can drop bunches of files, there's no need to drop them one by one
Apple has chosen not to allow dropping folders to this window, so drop only files (you can ZIP your folders and transfer ZIP-archives with iTunes, those ZIP-archives can be later unzipped inside GoodReader).
you can also transfer files and folders in the opposite direction - from GoodReader to computer
all files that you transfer with iTunes will appear in My Documents folder of GoodReader. You can use GoodReader's File Management tools later to move those files to any subfolder inside GoodReader.
