Function of the DLM file

The DLM file is temporarily saved while the file is downloading, and once the download is complete, the DLM extension is replaced with the original file extension, automatically.

It is important to note that if the Akamai Download Manager does not automatically replace the DLM extension with that of the original file, the file extension can be changed manually after the download is complete.
