Hi,
I've seen a few other discussions of this on the list but haven't seen
a definitive answer.
I'm trying to use "choose file of type" to allow a user to choose any
PowerPoint presentation. There seem to be two problems:
(1) there doesn't seem to be a single list of either UTIs or file
types which will cover all formats (and you can use only one)
Using the code below, I've found the following list of file types and
UTIs:
name:"97-2004.ppt",file type:"SLD8", file creator:"PPT3", type
identifier:"com.microsoft.powerpoint.ppt",
name:"97-2004show.pps",file type:"PPSS", file creator:"PPT3", type
identifier:"com.microsoft.powerpoint.ppt",
name:"macro-enabled-show.ppsm",file type:"PPSM", file creator:"PPT3",
type
identifier:"org.openxmlformats.presentationml.slideshow.macroenabled",
name:"macro-enabled.pptm",file type:"PPTM", file creator:"PPT3", type
identifier
:"org.openxmlformats.presentationml.presentation.macroenabled",
name:"ppshow.ppsx",file type:"PPSX", file creator:"PPT3", type
identifier:"org.openxmlformats.presentationml.slideshow",
name:"Classic Photo Album2.pptx",file type:"" file creator:"" type
identifier:"org.openxmlformats.presentationml.presentation",
If I create a list of file types, it won't let me choose the last one
(which doesn't have a file type). If I create a list of UTIs, it
doesn't let me choose some of the files (see below for an example).
(2) some files don't match even when the UTI is correct
To find out the list of file types and UTIs, I've created a collection
of PowerPoint files and done the following:
set pres to choose file
log file type of (info for pres)
I can use this to choose a PowerPoint Show (.ppsx) and find the
following:
name:"ppshow.ppsx", type:"PPSX", file creator:"PPT3", type
identifier:"org.openxmlformats.presentationml.slideshow"
but now if I try to do
set pres to choose file of type
"org.openxmlformats.presentationml.slideshow"
it doesn't let me choose that file (is that a bug?).
Has anyone else run into this? Is there a solution?
Thanks,
Brett
