You will know the disk space available on the disk you select and the estimate package size you're gonna export.
The bit depth is forced to 16 bits for the Normal and Height channels. The other channels are exported in 8/16 bits depending on your materials and the filters you used.
On the Export panel, you have access to the Export Queue system to follow the progress and get the folder link to go directly to your file explorer
