Remarks

AppleFile packs or unpacks file data to or from AppleSingle or AppleDouble format. The AppleSingle format allows a file's contents to be packed together with related file information, such as file dates, resources, icons, and so forth, into a single file. The AppleDouble format is similar, but different in that the file's contents are stored in one file, and the remaining file information (dates, resources, icons, and so forth) is stored in a separate AppleDouble header file.

In the MIME world, AppleSingle and AppleDouble are the preferred ways to transfer Macintosh files, with AppleDouble preferred over AppleSingle where possible. In actual practice, the BinHex format is common (most likely due to the fact that most Macintosh archives store files in BinHex format). The use of AppleSingle and AppleDouble in MIME is described in RFC 1740 and is referred to as MacMIME. MacMIME is an official Internet standards track protocol.

To use AppleFile for packing file data to the AppleDouble header format, first set the Format property to AppleFile.AppleDouble to set the format type to AppleDouble header, then set one or more of the following properties to set the file data: FileName, CreateTime, ModifyTime, BackupTime, AccessTime, ResourceFork. Next, call the Pack() method to pack all the file information into a single buffer. Finally, retrieve the PackedData property to get the packed AppleDouble header data.

Next, call the Pack() method to pack all the file information into a single buffer. Finally, retrieve the PackedData property to get the packed AppleSingle data.

To use AppleFile to unpack AppleSingle or AppleDouble file data, first set the PackedData property to set the packed data into the AppleFile object.
