I need try (VRayProxy filename: f)catch() to give me True

[Haider_of_Sweden]

If I run this

f = "file.obj"
try
( 
importFile f #noPrompt
)
catch()

I get true

If I run this

f = "file.vrmesh"
try
( 
VRayProxy filename: f
)
catch()

I get nothing, or at least not the "true" I need.

How can this be solved?

Apparently, what I needed was

selectmore (VRayProxy filename: f)
