QuickTime for Windows resource files
|
Q:
I am having problems using the FSpOpenResFile function on
Windows to open files containing Mac-style resources for
my application. It seems this function will only open resource
files with the extension .qtr?
A:
QuickTime for Windows can locate and read resource forks
in the formats listed below. It can also write resource data
into any of these formats where the resource fork is not
in the same file with the data fork. Those formats which
are "single-file" (resource fork and data fork
are in the same file) are read-only.
Note you can also write a QuickTime component to add support
for any additional custom formats. Check the QuickTime online
documentation (see <http://developer.apple.com/documentation/quicktime/qtdevdocs/RM/frameset.htm>)
for more information on writing QuickTime components.
Here are the names of resource files supported by QuickTime for Windows:
DOS floppy mode:
data: myfile.blah
resource: RESOURCE.FRK\myfile.blah
PCMacLan mode:
data: myfile.blah
resource: myfile.blah.#res
.QTR (QuickTime resource) mode:
data: myfile.blah
resource: myfile.qtr
|
Note:
The '.QTR mode' is the format produced by the QuickTime Rez tool
when run on Windows (the Rez tool is part of the QuickTime
for Windows software development kit). Typically, your executable
(.exe) or DLL will get its resources from a .qtr resource
file during program development.
|
RezWack mode:
data: myfile.blah
resource: myfile.blah
|
Note:
The RezWack mode format is read-only. Files in this format are
created by the QuickTime RezWack utility, which is provided
as part of the QuickTime for Windows software development
kit. This utility allows you to embed Mac-style resources
directly into a Windows DLL or .exe file. The QuickTime resource-management
routines are able to correctly locate and read resources
embedded with this utility in a .exe or DLL. This is the
preferred method for delivering resource forks in a commercial
product, as both the data fork and resource fork are combined
into a single file.

Apple Double mode:
data: myfile.blah
resource: %myfile.blah
Apple Single mode:
data: myfile.blah
resource: myfile.blah
Note: This format is read-only.
NTFS mode:
data: myfile.blah
resource: myfile.blah:AFP_Resource (NTFS named fork notation)
EtherShare mode:
data: myfile.blah
resource: .rsrc\myfile.blah
HFS on Linux mode:
data: myfile.blah
resource: .resource\myfile.blah
