You work as a forensic investigator. A recent inquiry from a local company called TriGo has caught your attention. On a routine file audit of their servers, TriGo has found some files that appear to be “corrupt” because each file uses the .xde extension. When TriGo personnel try to access the files, they show as “garbage.” Search the Internet for this file extension and summarize your findings. 
Write a one-page report detailing your results. Include at least one tool or best practice you would recommend to this client.
