importfl-1.2.1.zip (66K) a zipped hfs disk image and checksum file. The disk image can be mounted with Mini vMac. Includes source code.

ImportFl is an application to use in Mini vMac (version 3.0.0 or later) to import files into the emulated computer from the real computer.

When ImportFl is the active application running in the emulated computer, then any of the methods normally used to mount a disk image will instead import a file. For example, dragging the icon of the file to be imported into the Mini vMac window.

warning: When attempting to use ImportFl, if you see a dialog asking if you want to initialize the disk, choose “Eject”, not “Initialize”! This will happen if ImportFl is not actually the active application, in which case the file you are attempting to import is treated as a disk image. Choosing “Initialize” will turn it into a valid disk image, destroying parts of the previous content.

ImportFl is mostly useful for importing archives, since it only imports the data fork of a file, not Macintosh specific information such as the resource fork, the file type, the file creator, and comments. (In particular, applications are mostly contained in the resource fork, and so can not be imported with ImportFl. And aside from OS X, most other modern operating systems don't support resource forks, and so can not correctly store an old Macintosh application, and so there is nothing that ImportFl could import anyway.)

OS X has the built in ability to create an archive that preserves most Macintosh specific information. Right click (or click with the Control key down) on the icon of a file or folder, and choose the "Compress" command. The archive is created in the same folder with a name ending in ".zip". Such archives can be unpacked in Mini vMac with the MiniUnZp application, or using the more advanced miniunz from Adam P.

Another alternative is that recent versions of OS X include a macbinary command, which can be used from the Terminal to convert a file into into MacBinary format, which can be unpacked with binUnpk or Stuffit Expander. (Thanks to Ryan Schmidt and Samir Namer for pointing out this command.)

Already existing old archives can often be unpacked with Stuffit Expander 4.0.1. However, it is common to encounter a Stuffit file that requires a more recent version of Stuffit Expander than will run on a Macintosh Plus. In this case you should first uncompress it on a modern Macintosh, and then recompress into a new archive as described above. Or alternatively, you could uncompress it on a different Macintosh emulator, such as Basilisk II.

If you would like to import plain text, ClipIn may be more convenient.

If you would like to export files, see ExportFl, the opposite of ImportFl.

Since ImportFl doesn't receive Macintosh file type and creator information from the real computer, it sets the file type of the imported file to “BINA” and the creator type to “MvEx”. That creator type belongs to ExportFl, so double clicking on the imported file will launch ExportFl, if it is available.

Here is the md5 checksum for the download:

July 13, 2016 version 1.2.1 fixes a bug where ImportFl would not overwrite an existing file (after the Standard Put File dialog asks if you want to replace it). And the URL in the about dialog has been updated. Also, source shared with other Mini vMac extras has been updated, fixing a couple other bugs: ImportFl should now not crash in other emulators such as SheepShaver (though it still won't do anything useful), and it can save to MFS volumes, when the computer supports HFS (previously it had the wrong test, and would support MFS only on computers that didn't support HFS).
