However, most users are facing problems opening E01 file in Autopsy. Here are some sample queries we collected from different forum discussions.

Hello there. I am a forensic analyst by profession. I have given a forensic image that has been split into multiple E01 files such as .e01, .e03, .e04, etc. It’s taking hours to add to the autopsy. Can anyone suggest an alternative approach to speed up the process?
Hi, I am Jess. I am a digital forensic and cyber security grad student. My professor assigned a task to open E01 file autopsy and analyze the image files.
