There is a drawback to open a Document Library in Windows Explorer view and move multiple documents to other folders/libraries because the document’s properties get updated in the process (Date/Time, Modified, Modified By). This also applies to copying list data in data sheet view from one list to another.
To move the contents of a Library or List and preserve the item’s metadata/property values within the same site collection:
- Create a blank destination List or Document Library.
- You don’t have to worry about recreating custom fields. Move process will create the necessary.
- Site Actions > Site Settings >> Go to the ‘Site Content and Structure’ page.
- Navigate to your source List or Document Library and mark all the items that you would like to have moved.
- Then click on Actions >> Move
- You’ll then be prompted with a pop-up that will let you navigate to your destination List or Document Library.
- After you select the destination, press the OK button.
By this method, all of the document properties/metadata while moving list items or documents from one location to another should be preserved.
