The suffix is the most technically revealing part. “DLM” stands for Download Manager — a small executable that first downloads the full installation files rather than a single monolithic setup. “SFX” means Self-Extracting — the file can unpack itself without external archiving tools. When run, dlm.sfx extracts the actual installation components to a temporary folder and then launches the download manager to retrieve the remaining CAB files from Autodesk’s servers. autocad -2021- english-win-64bit - dlm.sfx

In summary, far from being arbitrary, the filename serves as a compact technical specification, guiding proper deployment of AutoCAD 2021 in professional environments.
