Thank you for your interest in our products. Pix4Dcapture requires space on the internal memory of the device to run. Then regarding the projects there are also saved on the internal memory by default but you can change the directory if needed.
To change the path of the directory go to the Home screen of Pix4Dcapture, tap Settings. In the section Advanced, tap Root directory path. Once you enter the new path, it will be set back to the default location in case it is not correct. Enter the path, press OK, then go the home screen, and go back to Settings. If your new path was correct, it should now be displayed.
If you want to change it to save the missions into the external SD card of the phone, the path towards the corresponding directory varies from one Android smartphone to the other. The standard path for Samsung mobiles should be something like: ‘’/mnt/extSDCard/’’
Pay attention to the fact that the path is case sensitive.
