Mmmm seems like value transformer would be another way to do it! I will
definitely look into both methods! Since my property is in fact only
used for display purposes, I guess it would make sense to use a
transformer to display it...

Now, assuming I want to bind an array of those File objects to a
Table View, however, what I would like to display in the table's
column is not the complete path of the file, but just the file name

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).
