Purpose and Function

Resume Downloads – If you are downloading the large Lumion 2024 installer (often 15–20 GB) via Lumion’s official client or a download manager, this cache file stores information about which parts of the file have already been downloaded. This allows you to pause and resume the download without losing progress.
Verify Integrity – The cache may contain hash values or chunk maps to verify that downloaded pieces are not corrupted.
Download Manager Sidecar – Many modern download tools (like Internet Download Manager, Free Download Manager, or Lumion’s own “Lumion Download Manager”) create a .cache file alongside the actual installer (e.g., Lumion_2024_4_2.exe or .zip). The cache holds temporary download data until the download completes, at which point it is usually deleted or merged. Can I Delete the Lumion-2024-4-2-Download
Browser Partial Download – In some cases, a browser like Chrome or Firefox will create a .cache or .crdownload file during an incomplete download. Renaming it manually is not recommended.

Scenario B: Downloading via the Official Lumion Client Installer

Lumion provides a lightweight stub installer (e.g., Lumion_2024_4_2_Downloader.exe). When you run it, the downloader creates a hidden cache folder (often in %temp%\Lumion\ or C:\ProgramData\Lumion\Downloads\). In that directory, you will find one or more .cache files, including Lumion-2024-4-2-Download.cache.

To locate it:

Press Win + R, type %temp%, and press Enter.
Look for a folder named Lumion or a file with 2024-4-2 in the name.
Alternatively, search your entire C:\ProgramData folder (ensure hidden items are visible in File Explorer).
