What is an AFF file?
An AFF file is a spellcheck dictionary file used by Kingsoft WPS Office and Apache OpenOffice, which are free Office suite applications. It contains information that describes the accompanying .DIC spellcheck dictionary file.
More Information
The AFF and DIC files are used to add new spellchecking dictionaries for different languages, such as Italian and French, to WPS Office. Users typically download .ZIP dictionary packages that contain the AFF and DIC files, extract the contents, then install them in WPS Office.

More Information
Arcaea is a video game in which players must press buttons in time to music. The game is developed by Lowiro and available for Android, iOS, and the Nintendo Switch.
Each Arcaea level consists of a song, saved as an OGG file, and one or more Arcaea charts, saved as AFF files. Typically, a level uses three AFF files, each of which corresponds to one of the level's difficulties (easy, medium, or hard). These files define the buttons a user must press in time to the song.
Some Arcaea modders use custom level creation tools to create their own AFF files. These files are often packaged within ARCOIDLEVEL archives, which are renamed .ZIP files.
How to open an AFF file
You can open an AFF file, to play and edit the chart it contains, with ArcCreate. ArcCreate is a fan-made version of Arcaea that includes a custom level editor. The level editor is available in the PC version of ArcCreate.
You can also use AffTools or ArcaeaChartRender to analyze and preview the chart an AFF file contains.
