In Windows 7 (PC) I am learning how to use "ADD TAGS" file properties with the aim of improving the searching for files.
Am I right in thinking that it IS possible to Tag the properties of these files: DOC PPT XLS JPEG, but NOT possible to tag these file types: DOCX PPTX XLSX GIF PDF.
What is the reason behind these differences?
Tagging old file types is less than fully useful! Do some editions of Windows 7 tag more type types than others?
