*1 Date folders and number folders are automatically named by the CPU module.
*2 The maximum number of storable folders is 32767.
*3 When bit 2 of SD955 (Restoration function setting) is set to on at the backup processing, the file is generated if it is not in the CPU folder,
and the setting information stored is updated if it is. (When bit 2 of SD955 is set to off at the backup processing, the file is not generated.)
Backup/restoration target data
Backup target data is all target data in the CPU module. ( Page 311 Backup/restoration target files)
Restoration target data is set with SD954 (Restoration target data setting). ( Page 324 Restoration target data)

■The number of CPU module backup data that can be stored in an SD memory card
The number of CPU module backup data that can be stored in an SD memory card is 32767. This number is equal to the
maximum number of storable folders.
The number of files that can be backed up and restored (the number of backup source data files) depends on the maximum
number of files of each model or drive.
