What program can I use to open the downloaded files?


Last Update vor einem Jahr

All of our video courses and collections are .zip compressed for easier and faster download, although you may stream most of them online from your iChess account.  If you choose to download please go to


and download the relevant course. You can also download from the links in the email invoice that you will receive in your inbox after purchase. Once downloaded, there are several options for uncompressing, which we describe below:

If you are a Windows user, we recommend using 7-zip, which works well with our files. While it is true that Windows 10 has an extractor, unfortunately, you may experience some inconveniences with long file names, so please use 7-zip if you encounter this issue.

If you are a Mac user, we recommend using The Unarchiver, a free Mac native app that should also work perfectly.

If you would like to uncompress the downloaded files on your Android mobile phone, we recommend that you download and open them with the Files by Google app on Google Play.

If you would like to uncompress the downloaded files on your iPhone, a nice choice for uncompressing our zip files is the free Files app on the App Store.

You successfully downloaded your extraction app/software. Way to go! Now, What? Here we go:

1) Just double-click the *.zip file, and the folder should be extracted automatically in the same location. (If not, right-click, highlight 'open with', and select your extraction software from the list).

2) Once extracted, open the folder. Inside, you will find the video files of the DVD content (as *.mp4) and any subfolders containing the PDF summaries and the PGNs for games analyzed (as *.txts) if these are included in the course.

3) For playing the videos, double-click the *.mp4 files, and a video player should open automatically. If your default player does not work, try using the free VLC player.

We hope you enjoy your learning experience as much as we delighted ourselves in choosing and making only top content for you.
