When you create a new dataset of type “upload your file”, and choose to upload a file named foo.csv, the file you upload is stored in DATA_DIR/uploads/PROJECTKEY/datasets/foo/foo.csv .
So if the question is about storage space, then yes, you indeed need to check that the server filesystem has enough space. But usually, you shouldn't need to worry about those files.
