Re-Naming Files
File name conventions differ for documents you download from the Internet. Some names may just be a series of numbers. Mendeley allows you to easily rename those files to aid consistency, identification and organization.
In Mendeley Desktop, select the document(s) you want to rename, and pull down the File tab and select Rename Document Files..
You get to choose the name convention by dragging fields to the position you want.
Organizing Files on Your Computer
You can also rename multiple files using the File Organizer. It also can sort your files neatly into a designated folder and sub-folders on your computer's hard drive. To access the File Organizer:
Mac: Mendeley Desktop>Preferences
Windows: Tools> Options
