DOWNLOADING FILES

TOP

Important: IDA has replaced the software that performs IDA Downloads with a new and improved method of downloading data. Our new approach offers several benefits and removes the requirement to have the Java Plug-in installed. Most browsers are changing their Plug-in support policies this year, while some browsers, such as Chrome, have recently stopped supporting Java Plug-ins. The new IDA Download relies on the built-in download functionality of the web browser and requires no additional software.

New IDA Downloader: Intro

IDA download functionality has been improved to make the download process quicker and easier:

Download Options

Image of 1-Click Download
Use the built-in functionality of your web browser to quickly download all the files in your collection to a single zip file.

Image of Advanced Download Split your download into multiple files. Use the built-in functionality of your web browser to download files or use your favorite Download Manager software to optimize your download speed and experience (see About Download Managers immediately below).

Download Managers

Software applications known as Download Managers may help you manage your IDA file downloads: they can automate downloads of multiple files and can keep track of large files seamlessly while you do other things or are away from your computer. A major advantage of most Download Managers is that if a download is briefly interrupted due to poor connectivity, that download will continue from the point where it was interrupted instead of restarting from the beginning.

IDA does not endorse or support any download managers and is not responsible for download errors or subsequent issues resulting from use of any third-party products. However, IDA has tested and suggests the following free products for your consideration:

Product Name Platforms Site
jDownloader Linux, Mac or Windows
uGet Linux or Windows
FDM Mac or Windows


UPLOADING FILES

Warning: Support for Java plug-ins has been removed in some recent web browser updates resulting in problems uploading files to the IDA. A new IDA Uploader is in development and planned for release in Summer, 2017. For those who are already experiencing problems uploading, an interim IDA Uploader that runs as a stand-alone program with no Java plug-in requirement is now available. Please see the IDA Uploader Instructions section below for details.
