Troi File Plug-in 2.0
Compatibility
FileMaker Pro 17 to FileMaker Pro 21 (2024)
Considerations
On macOS it is possible to have multiple disks with the same name. In this case the function will unmount the first disk that matches the diskname.
Since version 2.6 this function is also available on Windows. However it does not physically eject removable media, like a CD-ROM.
Example
Set Field [ result ; TrFile_UnmountDisk ( "-Unused"; "Mac HD:" ) ]This will eject the hard disk “Mac HD”, provided it is not the startup disk. On Windows an example is:
Set Field [ result ; TrFile_UnmountDisk ( "-Unused"; "K:" ) ]This will unmount the mapped drive “K:”
Example 2
We assume that in your FileMaker file the following fields are defined:
gErrorCode Global, number
gDiskName Global, textgFilePath should contain the path to the disk, for example “Archive CD:” (Mac). In a script add the following script step, which will eject the disk specified by gDiskName:
Set Field [ gErrorCode ; TrFile_UnmountDisk ( "-Unused" ; gDiskName ) ]Used in example file
DiskMount.fmp12
