Questions and answers

  • What is a ".DLM backup" file and how does it differ from other backup file formats?

    A ".DLM backup" file is a backup file format used by Autodesk software applications, such as AutoCAD. DLM stands for "drawing list manager," which is a component of Autodesk software used for managing drawings and project files.

    The .DLM backup file format is specific to Autodesk software and is designed to store a backup of the drawing list and associated project files. It contains information about the drawings, their locations, and other project-related data.

    The main difference between a .DLM backup file and other backup file formats is that it is specific to Autodesk software and is tailored to backup and restore the drawing list and project files. Other backup file formats, such as .ZIP or .RAR, are more generic and can be used to store a wide range of files and data from various applications.

    In summary, a .DLM backup file is a specialized backup format used by Autodesk software to store and restore the drawing list and associated project files, while other backup formats are more generic and can be used for backing up various types of files and data.

  • How can I create a ".DLM backup" file for my data?

    To create a ".DLM backup" file for your data, you can follow these general steps:

    1. Identify the software or application you are using that supports ".DLM backup" files. This file format is not widely known, so it may be specific to a particular software or system.
    2. Check the software's documentation or settings to see if it provides an option to create a backup in the ".DLM" format. Look for terms like "backup," "export," or "save."
    3. If the software has a backup/export feature, follow the instructions provided to create a backup. Typically, you will need to specify the location and name of the backup file, as well as the data you want to include.
    4. If the software does not have a built-in backup/export feature, you may need to explore alternative methods. One option is to manually copy and paste the data you want to backup into a text file or spreadsheet, then save it with a ".DLM" file extension. However, keep in mind that this may not preserve all the original formatting or metadata.
    5. If you cannot find any information or options related to ".DLM backup" files, it is possible that this file format is specific to your organization or a custom solution. In such cases, you may need to consult with the software provider, IT department, or support team to understand how to create a backup in this format.
