Downloading multiple files in Storage Browser

Learn how to download multiple files in Storage Browser while adhering to prerequisites and configuration limits.

In Data Explorer, you can select multiple files and download them in a single operation. To prevent server load spikes and maintain web browser stability, Data Explorer processes multiple files sequentially with a fixed 5-second delay between each file download.

Verify that the following requirements are met before downloading multiple files:

  • Data Explorer file download option enabled — The enable_file_download_button configuration property is enabled in Storage Browser. This setting applies only to files and not to folders.
  • File count limit — The number of selected files is within the threshold set by the storage_browser_parallel_download_threshold configuration property (default is 5). If you select more files than the configured threshold, the download action is not displayed.
  • File size limit — Every selected file must be less than or equal to 50 MiB. If any selected file exceeds 50 MiB, the multiple file download action is not available. You must download files exceeding 50 MiB individually.
  • Browser permissions — Your web browser must allow multiple automatic file downloads.
  1. Log in to the Data Explorer interface.
  2. Select the files that you want to download.
  3. Select Download.
    1. If you select a single file, the file downloads directly without displaying a download status window.
    2. If you select multiple eligible files, the download status window opens and performs the following actions:
      • Displays the progress count in the window header (for example, Triggering files download (2 / 5)).
      • Downloads files sequentially with a 5-second delay between each file.
      • Updates the status of each file to Pending after the download is initiated.
  4. If your web browser displays a prompt requesting permission to allow automatic or multiple file downloads, select Allow.
  5. Keep the download status window open until all files finish downloading.

To update the file count threshold property, configure the following parameter in the [filebrowser] section of the hue-safety-valve configuration file:

[filebrowser]
storage_browser_parallel_download_threshold=5
Configuration Property Description Default Value
storage_browser_parallel_download_threshold Specifies the maximum number of files that you can select for a single multi-file download operation. If the selected file count exceeds this value, the download action is hidden. This setting caps the queue size; files continue to download sequentially. 5
