This can take up to five minutes and is conducted on first boot. Make sure to not remove power or SD card during the first five minutes after upgrading the device. Recordings made with firmware earlier than 5.20 will not be readable on the SD Card from firmware 5.40 and onward. Backup important recordings and reformat the SD Card after the firmware upgrade. 5.50.4.6:L23 Time modifiers used in the field "Create folder" is only used upon activation of the rule, hence no new folders are created with the current time during an active rule. To have new folders created with time modifiers you should add them in the "Base filename".
