# KeepExisting

Set `KeepExisting` to `False` if you want to overwrite the whole custom term weight file.

By default, if you have an existing custom term weight file, IDOL Server updates the file with the values in the new one. IDOL Server adds any terms that do not exist in the current file, and updates the weight for any terms that do exist.

If you set `KeepExisting` to `False`, IDOL Server deletes the existing file and replaces it with the new one.

You can also set `KeepExisting` to `False` without adding a new file. In this case, IDOL Server uses the default term weights and deletes the custom file.
