How can I create my own UTI

[Pierre Leblanc-2]

Hello,

I've been trying to set up my own UTI for use with Select document.

I use a custom extension for files that my apps exchange data through.

The extension is .a5

I tried to setup a custom UTI (com.imagora.a5) by editing 4D's
info.plist file by adding :

<key>UTExportedTypeDeclarations</key>
<array>
   <dict>
     <key>UTTypeConformsTo</key>
     <array>
       <string>public.data</string>
     </array>
     <key>UTTypeDescription</key>
     <string>Macs A5 file</string>
     <key>UTTypeIconFile</key>
     <string>4DDataBlob.icns</string>
     <key>UTTypeIdentifier</key>
     <string>com.imagora.macs.a5</string>
     <key>UTTypeTagSpecification</key>
     <dict>
       <key>public.filename-extension</key>
       <array>
         <string>a5</string>
       </array>
     </dict>
   </dict>
....

No luck. When I call Select document ("";"com.imagora.a5";"";0), all
files are selectable.

Anybody with experience on that ?

Hi Pierre,

You might need to update the LaunchServices database (using the lsregister command line utility).

Give the following a try:
/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Support/lsregister -R -f -v /Applications/4D\ v12/4D.app

Except for the typo in the UTI (com.imagora.a5 instead of
com.imagora.macs.a5), there was one additional step : move the package
around !
It appears that info.plist gets reparsed only when the package is copied
(not just moved) elsewhere.
So I just copied the 4D package to another location and *boom*, it worked.

Sorry for the noise.

Pierre.

Thanks Rob, I'll try that.
