This function can also be used on FileMaker Server.


Set Variable [ $ErrorCode ; TrFile_ExportToFile ( "-OverwriteExisting" ;

This will create a file photo.jpg with the contents of the container field. Note that this will overwrite an existing file.

Example 2

Say you want to export the contents of a container field of all records of a found set to disk. We assume that in your FileMaker file the following fields are defined:

  gErrorCode	Global, number
  theContainer	Container

In a script add the following script steps:

Set Variable [ $ErrorCode ; 0 ]
Go to Record/Request/Page [ First ]
    # Build the path:
    Set Variable [ $DestPath; Value: Get ( DocumentsPath ) & theContainer ]
    Set Variable [ $Container ; theContainer ]
    Set Variable [ $ErrorCode ; TrFile_ExportToFile ( "-Unused" ; $Container ; $DestPath ) ]
    Exit Loop If [ Left ( $ErrorCode ; 2 )  = "$$" ) ]
    Go to Record [ Next; Exit after last: On ]
End Loop
Set Field [ gErrorCode ; $ErrorCode ]
