Is there a way to make Blender auto import files that are not .blend when you open them?
For example if you open a .fbx file by double clicking on it, and you have Blender set as default application, then import it to a new .blend.
Is it possible to make Blender import this .fbx file just like you would do it manually by using File > Import > FBX?
By default, Blender just opens up and loads default new scene when you open anything that is not .blend file.
No, Blender doesn't support this. Mainly because there are many options you may want to configure while importing a file.
However if its vital for your work-flow, writing a script to do this is not such a difficult task.
eg:
blender --python /path/to/auto_open.py --
Contents of auto_open.py
import os
from sys import argv
argv = argv[argv.index("--") + 1:]
format specific options... change as you like
args_fbx = dict(
# global_scale=1.0,
)
args_obj = dict(
# use_image_search=False,
)
args_3ds = dict(
# constrain_size=0.0,
)
import bpy
for f in argv:
ext = os.path.splitext(f)[1].lower()
if ext == ".fbx":
bpy.ops.import_scene.fbx(filepath=f, **args_fbx)
elif ext == ".obj":
bpy.ops.import_scene.obj(filepath=f, **args_obj)
elif ext == ".3ds":
bpy.ops.import_scene.autodesk_3ds(filepath=f, **args_3ds)
else:
print("Extension %r is not known!" % ext)
if not argv:
print("No files passed")
File associations typically add the file to the end of the command to form something like this:
blender --python /path/to/auto_open.py -- /home/me/my_model.fbx
Setting file associations can be done via this script (to save you having to do it manually), tested on Linux with Gnome.
Run this once bash blender_auto_import.sh

The above answer is absolutely wonderful I did however have to edit the script a bit to prevent errors from making it function as expected. According to the error, objects do not have an unlink function.
I substituted the clearscene() function to simply remove the default Cube as the light and camera are of no concern for my particular usage. Working in 2.82

I'm not a programmer or anything like this. How should I to use these scripts in windows? When its done I can click a fbx file and open it directly from the double click on blender or should I click the script? Please, I need a for dumies guide.
You should put
– StackHola Feb 28 '23 at 14:14blender --python /path/to/auto_open.py -- %1into a .bat file, either setting your Path to include blender install dir or putting it by hand (I find it useful if you have several blender install and make several open with script). Mind the%1. Then use the contextual menu open with to set the bat file as the opening program.
