Now, assuming I want to bind an array of those File objects to a

What would be the best way to achieve that? Basically: I want to
bind my column to a property that doesn't really exist (i.e. only
part of the filePath property)...
You can use a custom value transformer. You would implement
+transformedValueClass to return an [NSString class] and -
transformedValue: to return the lastPathComponent of the passed in
string. Set the transformer for the binding and you should be set.
There are a few samples that you can reach from the Xcode docs
demonstrating this (just look up NSValueTransformer).
