Mendeley's file organizer can automatically rename your PDFs and file them in a clear folder structure, making it easier to find your files outside of Mendeley.
Open Mendeley's File Organizer which can be found under Tools > Options.
In the tab, you can select:
- Organize my files: to make a copy of all documents added to Mendeley within one folder
- Sort files into subfolders: to create a folder structure based on selected document details
- Rename document files: to rename the often non-descriptive names of your PDFs to file names that are more meaningful, including the author, journal, year, and title
