Actually, that isn't a bad idea. There doesn't seem to be a way of
getting input to a Python script, as raw_input() doesn't appear to work
in the Python Shell (in the PV GUI, at least) either.

I didn't mention Python because it doesn't give you a way of popping up
a file chooser - you have to edit the script and change the file name.
Maybe we should add a Python command to pop up the file chooser... It is
not super easy but if there is enough demand, we can do it. Feel free to
add a feature request to the bug tracker or uservoice.

I would suggest doing this in Python in order to avoid reading the full
resolution dataset by default. When opening a file, paraview forces you
to click Apply before you can do anything else (such as creating an
Extract Subset filter). Thus, the data reader uses
UPDATE_EXTENT=WHOLE_EXTENT and you may run out of memory before being
able to subset the grid.
if instead, you instantiate your reader, do not execute it, do not
create a representation for it, then create an Extract Subset with the
VOI you desire, and then execute the whole thing, you will end-up
passing the VOI extents upstream directly to the reader, and your reader
will only execute once with the correct extents.
Use the python shell and the followin example:
reader = XMLImageDataReader( FileName= '/path/to/data/foo.vti'] )
reader.PointArrayStatus = ['data1']
ExtractSubset1 = ExtractSubset()
ExtractSubset1.VOI = [2000, 2255, 2000, 2255, 2000, 2255]
DataRepresentation2 = Show(ExtractSubset1)
Render()
