I have a program that he tries to get data from the concrete device after the incident of the device and save it on the hard drive. Save:
FILE * fp_binary = fopen (appadata, "wb"); Frame (buffer, size (four), size (buffer), FP_binary); Fclose (fp_binary); Therefore, when I run this program it works fine, but if I disconnect the device and store it again: 
The appadata is the path to the appadata folder and the file name has always been re-created with a different buffer
