Every file has personal information and properties such as Name, Type, Folder Path, Size, Date Created, Date Modifed, Author, Owner, Computer etc. These settings can be changed and/or removed in Windows 8. There could be several reasons for doing so. However, here is how you can do it in Windows 8
1. Right click any file for which you want to make changes in properties and personal information and click Properties
2. Now go to the Details tab and click Remove properties and personal information
3. You can either create a copy with all the possible properties removed, or remove the properties from the file by selecting any one of the two options.
