File Exchange 3.0

File Exchange allows users to set mappings from filename extensions (ex.: ".TXT") to Mac OS file types (ex.: 'TEXT'), to mount DOS SCSI disks and drive containers, and to set File Translation preferences. The following changes have been made in File Exchange:
  • File Exchange Features

    • PowerPC-native.

    • Consolidated interface for PC Exchange and File Translation (formerly Mac OS Easy Open).

    • Supports AppleScript.

    • Integrated editing of Internet Config extension mappings.

  • PC Foreign File System Features

    • PowerPC-native.

    • Mounts all available PC volumes at startup.

    • Can also mount all available PC volumes "on the fly".

    • Supports multiple SCSI busses.

    • Uses HDI driver (from DiskCopy) to mount PC disk images.

    • Improved read/write/cache code path.

    • Internet Config integration.

    • Desktop Database support.

    • Permits File Sharing of PC volumes and disk images.

  • AppleScript support includes:

    • Query and create translation and extension mappings.

    • Query or change control panel settings.

  • Corrected a problem where a particular data file format saved to PC disk was unreadable. The error returned by SetFPos was not being handled correctly when an attempt to set the mark past EOF was being made.

  • Two-byte characters in traditional DOS FAT "8.3" format file names weren't being displayed in Get Info. This has been corrected.

  • Determines disk type (FAT12, FAT16, FAT32) using disk geometry; this fixes problems with low-capacity FAT16-formatted PC cards.

  • The PC foreign file system's "mimicry" of HFS has been improved. Now, under as many circumstances as possible, the PC foreign file system behaves the same as HFS.

  • Allows use of PC disks with allocation block size of 32K or larger (for example, 2 GB disks).
