The YDC file extension is used for Yu-Gi-Oh! Card Deck files. These deck files are created by Yu-Gi-Oh! Power of Chaos game users to save card decks. YDC files are located in the avatar profiles folder of a Yu-Gi-Oh! game installation. Users can export and import YDC files between different Yu-Gi-Oh! installations to transfer deck data.
If your software does not open a YDC file when you double-click it, try right-clicking the file. Then select “Open With” and choose the Yu-Gi-Oh! Power of Chaos program. Updating to the latest version of this software may allow opening files in newer YDC formats.
The most common issue with YDC files is that Windows does not associate them with Yu-Gi-Oh! Power of Chaos. So when you try to open a YDC file, another program starts instead. To fix this, associate the YDC extension with Yu-Gi-Oh! Power of Chaos in the Windows Registry.
Over 1500 different file types use the YDC extension. But most are incompatible. The Yu-Gi-Oh! Card Deck Format and Yu-Gi-Oh! Power of Chaos software were developed by Konami. So YDC files were likely created by Yu-Gi-Oh! Power of Chaos.
