NOTE: In order to use External Storage, you must be a Pro Plus subscriber or above. This also only applies to OptiSigns Devices, and will not appear on any devices not manufactured by OptiSigns.
If you feel there is not enough storage on your device, you can use the USB drive or micro SD card as extra storage to add additional storage capacity to it.
After you plug in the USB drive or micro SD card on your device, go to the Edit Screen tab.
Click Advanced, then click More:
Check "Use external Storage" and select Auto Detect in the "External Storage Path".
After that, the OptiSigns app will use the external storage on this device.
