SIMATIC memory card
12.1 SIMATIC memory card – Overview
Deleting content from the SIMATIC Memory Card
You have the following options for deleting the content of the SIMATIC Memory Card:
● Delete files using Windows Explorer
● Format with STEP 7
Note
If you format the card with Windows tools, you will render the SIMATIC Memory Card
unusable as a storage medium for a CPU.
Deletion of files and folders is permitted, with the exception of the "__LOG__" and
"crdinfo.bin" system files. The CPU needs these system files. If you delete the files, you will
no longer be able to use the SIMATIC Memory Card with the CPU.
If you have deleted the "__LOG__" and "crdinfo.bin" system files, format the SIMATIC
Memory Card as described in the following section.

Formatting the SIMATIC Memory Card
