To delete multi-version objects, your account must have the tos:DeleteObjectVersion permission. For specific instructions, please refer to the Access control.

Please exercise caution when performing delete operations, as files cannot be restored once deleted.

warning

This operation will delete all multi-version objects in the specified directory. Please proceed with caution.

For an example of how to delete all versions of all objects with a specified prefix, refer to Delete object versions—Delete all objects with a specified prefix.

Clear all incomplete multipart uploads for objects under the specified prefix in the bucket

The following code demonstrates how to delete all incomplete multipart uploads for objects under a specified prefix in the bucket-example bucket.
