Easy to use ‘touch’ command for windows/gui

TouchPro by JD Design

TouchPro allows you to change any combination of file time attributes through a file’s property pages. It fully integrates into Windows Explorer giving you the ability to affect the timestamps of:

  • Individual files
  • The results of any file searches possible with Explorer. For example: particular file types, or for files within a date range.
  • Entire folder hierarchies

The registered version of TouchPro enables extra facilities:

  • Separate time & date modification.
  • Touch files and/or folders.
  • Touch read-only files and folders.
  • Save settings.
  • Time offset modification – useful if your computer or camera’s date is set incorrectly and you need files timestamps changing to the correct time.
  • Load the time from the timestamp of a file or folder, or from embedded time properties in pictures, email or Microsoft Office documents.
  • Select 24 hour time, and long or short date format.
  • Command line version.
  • Context menu operations to Touch with the saved settings, or the current time.
