# How Do I Check Whether Folder Copy Is Complete During Job Training?

In the script of the training job boot file, run the following commands to obtain the sizes of the to-be-copied and copied folders. Then determine whether folder copy is complete based on the command output.

    import moxing as mox
    mox.file.get_size('obs://bucket_name/obs_file',recursive=True)

get_size indicates the size of the file or folder to be obtained. recursive=True indicates that the type is folder. True indicates that the type is folder, and False indicates that the type is file.

If the command output is consistent, the folder copy is complete. If the command output is inconsistent, the folder copy is not complete.
