Database file used by FileMaker, a program used to create, manage, and share databases; contains a user database stored in a proprietary format; used for importing data, creating custom reports, and sharing databases and results from data analysis.
USR databases use a complex file format to store data, scripts, layouts, and images. They can be exported into a variety of formats using FileMaker Pro. Data can be imported from text files, Excel documents or Bento databases.
USR files are sometimes stored as UFSR files in Mac OS X.
