DLM File - opening and understanding

Did your computer fail to open a DLM file? We explain what they are used for and recommend software that we know can open or otherwise handle your .DLM files.

What is a DLM file?

Files that contain the .dlm file extension are commonly associated with the Adobe Download Manager and the Akamai Download Manager applications.

When the Adobe Download Manager or the Akamai Download Manager is in the process of downloading a file, the file is temporarily saved with the .dlm file extension during the download process. Once the file has completed downloading from the Internet, the .dlm extension is removed and the proper file extension is assigned to the file.

The FileMaker Pro software application also uses the .dlm file suffix. These DLM files contain data files that are referenced by the FileMaker Pro application.
