Notes about the DEK file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries
, unused processes and other unfavourable system settings to identify slowdown issues.
The DEK file type is primarily associated with 'Memorize-It' by Side-Eight Software. Memorize·It is a multimedia flashcard application that allows you to create your own decks of flashcards incorporating text, sound, pictures, and drawings. Cards can be moved between decks or copied to build new decks. Interactive quizzing with Memorize·It automatically keeps track of the hardest cards.
