Difference between model.onnx and model.onnx.data

🤗Optimum

Hi team, i am new to optimum and have used the onnxruntime library a bit previously.
When i try to convert a model using onnxruntime, i get only one output file say model.onnx
but when i tried the below command of the optimum,
!optimum-cli export onnx --model BAAI/bge-m3 bge-m3-onnx-model
there were 2 file 1) model.onnx. 2) model.onnx.data

I though that i will only be getting one file named model.onnx.
Can anyone please explain me this.

When converting large models to ONNX, External Data (.data) seems to be output at the same time.
