5. Click on Read Data

6. Go and find your partion in C:\Users\$Username\AppData\Roaming\Qualcomm\QFIL\COMPORT_$NUM, where $Username is your user name and $NUM is your port number. You are suggested to add partion name in front of the file name, e.g. systemReadData_ufs_Lun0_0x7eb48_Len1048576_DT_26_12_2019_05_12_33. Because you need at least the partion name and the Lun to locate a partion.
