  • Windows Service that is auto started. Keep track using a timer over all currently executing processes and look for iexplorer.exe process with title containing the desired folder. – Shadow The GPT Wizard Feb 11 '13 at 13:05

    Just because the answer is likely "no" it doesn't mean that the question is ambiguous, vague, incomplete, overly broad, or rhetorical. – dtb Feb 11 '13 at 13:22

I am not sure about this but this is what I would do/try,

have a C# program which starts up on logon Open C# application on log on or just have your program running in some way and use FileSystemWatcher Class you can make use of LastAccess notify filter and have your C# code get executed . 

    // Create a new FileSystemWatcher and set its properties.
    FileSystemWatcher watcher = new FileSystemWatcher();
    watcher.Path = "folder path";

     /* Watch for changes in LastAccess and LastWrite times, and
       the renaming of files or directories. */
    watcher.NotifyFilter = NotifyFilters.LastAccess;

    // add event handler

Hope this helps.

  • That doesn't tell you if the folder was opened by Windows Explorer or just accessed by some arbitary process. – Ofer Zelig Feb 13 '13 at 05:17
