finding references in trend files (PHV)

im deleting a number of deltav modules in version 11.3.1 and would like to know if there is a quick method to review all my custom process history view trends to determine if they contain references to the deleted modules. i dont want to have to open each trend file manually and review the references manually. any ideas?

  Hi Stuart,
  The PHV files are not readable but the tagnames appear correctly when they are opened via a text editor.
  
  You can use application like Notepad++ to search for the module names in the folder where all PHV files are stored. Most text editors have this search in folder functionality.
  
  You might need a some investigation to find the correct string to search for.
  The easiest option is to create a new PHV with the module name you wish delete and view it via text editor. That will help you figure out the extact text to search.
  
  Regards
  Amod

  I wrote a VBA routine some time ago that extracts a list of parameters from phvc files which might be of use. See this file.
