Abstract: The collection and analysis of volatile memory is a vibrant area of research in the cyber-security community. Collecting Volatile and Non-volatileData. As per forensic investigator, create a folder on the desktop name case and inside create another subfolder named as case01 and then use an empty document volatile.txt to save the output which you will extract. This type of data is called "volatile data" because it simply goes away and is irretrievable when the computer is off.6 Volatile data stored in the RAM can contain information of interest to the investigator. It gathers the artifacts from the live machine and records the yield in the .csv or .json document. data in most cases.
