One of the easiest and best things you can do to manage your data is to come up with a consistent file naming system for both folders and individual files.
Creating folders to keep similar information together can expedite finding files at a later point. Give the folder names meaning. It may make sense to number the folders in order to keep the folders in a particular order, otherwise the folders will be organized in alphabetic order.
File Naming Conventions
Consider selecting a name for a file that makes sense for the project as well as the date that the file was created. Using a standard such as <project or grant name>_<YYYYMMDD>_<version number (optional)>.<file extension> will help keep track of your files, particularly in situations where many files are being created for the same project.
Note: Refrain from using any special characters in the file name, such as ,!@#$%^&*(), as well as a blank space. The only period that should be in the filename is the one that directly precedes the file extension (i.e., .pdf, .xlsx, .docx).
