Explanation

When using the COPY INTO <location> command to unload data to an external stage (e.g., Amazon S3, Azure Blob Storage, or Google Cloud Storage), the maximum individual file size Snowflake supports is 5 GB. This limit is driven by the underlying cloud storage provider's single-part upload constraints. To manage large datasets, Snowflake supports the MAX_FILE_SIZE parameter to split output into multiple files, each under the 5 GB limit.
