1. The epcontrol folder is generated in root of USB memory, and created the file as follow.
1) epcontrol_key : Key file for using decoding.
2) epcontrol_data : Encrypted Log Data
3) error_log : This is a folder that saves error_log and
kernel_log by abnormal termination.
→ If abnormal termination is generated, the files are saved by
increasing number like this – error_log.1 ~ error_log.10.
→ You can check the last saved log by opening
error_log_count. It will be recorded with the final log
number.
→ (Reference) If the set is dead by saving log in USB,
error_log and kernel_log is saved not in USB but in set. If
you want to save a file from set to USB, reboot the set first
and then you can check the log file in error_log folder when
log storage function is executed.
In the case of needing log folder saved problem before
rebooting, you have to make a back-up.
→ All of the files in error_log folder is needed to decode by
using epcontrol_key
4) backup : back up file in epcontrol_key and
epcontrol_data is saved.
→ If the saved files in the old days are existed when storing
log is started, files move to backup folder.
