Hello,

I had downloaded EgoExo4D V1 default set at \<data\_path\>. I then again downloaded EgoExo4D V2 by providing the same \<data\_path\>. I don’t know if it redownloaded the entire dataset or only updated the affected files. I realize that this may be a mistake and I may have corrupted the versions. My doubts are:

- Will it update the entire dataset and now my dataset is v2?
- Are meta files like metadata.json, captures.json, takes.json, etc consistent with the rest of the dataset?
- How will it affect the video files, vrs files, trajectory files, calibration files etc?

Thanks.  
Best,  
Chaitanya
