Extract Links for Mass Downloads with JDownloader - A How-To Guide
Streamlining Mass Downloads with JDownloader and Webmaster Toolkit
Here at MakeUseOf, we’ve explored numerous download managers. Popular choices among Windows users include FlashGet, Free Download Manager, and Download Accelerator Plus. For those seeking a browser-integrated mass downloader, DownThemAll is often recommended. However, JDownloader, while sometimes considered for more experienced users, has rapidly become a preferred tool for many.
This guide demonstrates how to utilize JDownloader, alongside a straightforward, free web-based tool, to efficiently download multiple images or files from publicly accessible directories and websites.
Finding Open Directories for Download
As an example, we’ll utilize an open directory discovered on the /r/opendirectories subreddit on Reddit. This platform is an excellent resource for locating substantial amounts of downloadable content. Specifically, we’ve identified a directory containing a collection of sound effects.
Let's examine a directory featuring sound effects for animals and birds.
For those who prefer to acquire everything available, the subsequent step involves accessing Webmaster Toolkit's Link Extractor. This tool is designed to extract links and images from any website provided to it.
Copy the URL of the open directory and paste it into the Link Extractor. Since we are interested in links, we will extract HREFs, rather than IMGs. Extracting IMGs would be appropriate for downloading images directly.
Select and copy all the extracted results, with the exception of the final entry. The last entry typically represents the parent directory, essentially navigating one level up. When downloading from multiple open directories, excluding this final result is advisable. However, including it will only result in downloading an HTML webpage, so it isn't critical.
Ensure the copied links are stored on your clipboard.
Configuring JDownloader for Mass Downloads
Next, download and launch JDownloader.
Begin by specifying the destination folder for your downloaded files. Navigate to the Settings tab, where you’ll find the relevant options.
After selecting your desired directory, switch to the Linkgrabber tab. This feature within JDownloader verifies the validity of links, preventing attempts to download non-existent files or pages.
Click Add URL(s), located near the bottom left of the window.
JDownloader attempts to import the URLs from your clipboard. However, the application may encounter issues with URLs containing spaces.
Open Notepad. Paste the list of URLs into the editor. From the Edit menu, select Replace…. In the Find what: field, enter a space. In the Replace with field, type "%20". This is the hexadecimal representation of a space. Click Replace All. This process will replace all spaces with their hexadecimal equivalent.
Copy the modified list of URLs. Delete the existing single line in JDownloader’s Linkgrabber and paste the updated list. JDownloader will then analyze each file and display the total download size.
Initiating and Monitoring the Download
Click the play button to begin the download process. You will be automatically redirected to the Downloads tab, where you can monitor the progress of your downloads.
Remember that the link extractor can be used to extract either HREFs or IMGs. This method is equally effective for saving images from a specific page, forum thread, or any other website containing numerous images.
