A MEM file is a data file created by GreekToMe, a cross-platform Greek New Testament study program. It saves the state of the different options on the user interface, which may include the book, verse, word, lexical word, author, and grammar lists. MEM files allow memory data to be saved and restored at a later time.

Memories can be exported by selecting File → Export Memories... from the application menu. You can import memories by choosing File → Import Memories.... NOTE: Future versions of GreekToMe may not be able to import older memory files, so users should consider them expendable.
