.FPT File Extension
File Type 1FileMaker Pro Database Memo File
Database file created by FileMaker Pro, a relational database program; contains textual information representing a "memo;" used to describe a database with raw text instead of using a standard database field, which typically is limited to fewer numbers of characters.
FPT files do not contain the actual database information. They only store the memo comments.
File Type 2FoxPro Table Memo
Contains textual notes about a table (.DBF file) used by a FoxPro database
File Type 3Alpha Five Table Memo File
Memo file created by Alpha Five, a desktop, web, and mobile application IDE; contains any memo fields that are created in the .DBF file; only exists when a memo field is defined in a DBF file; linked to a DBF file, any changes made to the DBF file will alter the FPT file.
The FPT file is created by Alpha Five because tables in DBF files have width limitations on how many characters can be in a column. The memo format in FPT files is not limited, they can have any alphanumeric (a string of data with numbers and letters) length. So Alpha Five creates a ten character field in the DBF file that references the memo location in the linked FPT file that contains all of the data for that record in the table.
NOTE: In 2013, Alpha Five became Alpha Anywhere.
[Name of your table].fpt - When a memo field is defined in your table, the FPT file will be created with the same name as your table.
