Dynamic Segmentation

jDM adds connections dynamically instead of creating segments just before download starts. New segments are added depending on the download speed and remaining file size. It adds new segments when one or more connections finish downloading. Dynamic segmentation provides significant performance improvements especially for large files.

Browsers Integration

Use jDM Extensions to catch downloads with just one click in your browser. When you start a download in your browser jDM intercepts it and starts downloading in the app.

jDM also adds “Download with jDM”, ”Download Selected with jDM” and ”Download All with jDM” context menu items in the browser to easily add multiple downloads.

Grab Websites

Download websites to your local directory for offline browsing. jDM explores the website and shows all files that are found on the server. You can choose the files you wish to download. jDM creates a group for these files and downloads them.
