One way to access the File Analyzer is from the File Finder.
From the handbook under "File Analyzer" chapter:
"You can access the File Analyzer from the File Tool. For example, just drag and drop some files to the jv16 PowerTools and the File Tools opens, then select the files and click More Functions > Analyze."
