FMTR files are associated with FileMaker Pro, database software for Microsoft Windows and Apple Mac OS X. They contain data used during FileMaker transfer operations and serve an internal purpose within the application.
An FMTR file is distinct from a normal FileMaker database and generally is not intended for editing as a standalone data file.
Open an FMTR file with a compatible version of FileMaker Pro for Mac. The file may be handled through FileMaker's transfer functions rather than opened as a normal document.
If a compatible version of FileMaker Pro can read the file, use its transfer or export functions to move the data into a current FileMaker database or another supported format.
