# Is there a difference between imported file types?

I've found a model on a site that I'd like to use but it doesn't come in a Blender format, so having never purchased a model before I'm just wondering which format I should buy? The formats available are .3ds, .dxf, .obj, and .max. Are they all essentially the same? I've seen in the Add-ons that these can all be imported, but I don't want to waste my money on one that won't work properly etc., so is there a type that's known to work better?

• 3ds is deprecated, bad suggestion. The most modern file format is alembic. .obj is really old and really limited in features, it is still in use because it is human readable and easy to implement for a developer compared to file types like .fbx or .dae, which have a ton more features. – p2or Sep 27 '16 at 13:03
