Interesting. I tried that in Windows and the system shows an error dialog
saying that multiple files can be selected only if in the same folder.
Probably that's why we introduced that limitation in the GTK driver.
We have the MULTIVALUEid attribute that can be used. But its definition
implies that all files must be in the same folder.
Maybe we can use an extra attribute to make MULTIVALUEid to include full
paths. I'll think about that.
Best,
Scuri
