Does anyone know if it's possible to access the File > Recent Documents list with a script? Sorry if this has already been asked, I tried to do some digging but haven't been able to find anything :-(
You can try to get this information from the Preference file which is located here on windows:
C:\Users\<UserName>\AppData\Roaming\Adobe\Adobe Illustrator 21 Settings\en_US\x64\Adobe Illustrator Prefs
When I scroll all the way down to around line 5500, there's the list of files:
So, you can actually access their information while Illustrator is running, like so:
var pref = app.preferences.getStringPreference("plugin/FileList/file0/name");
After sniffing around like so, I am under the impression that they order the files by most recently opened, so do not expect "file0" to be the file at the very top.
