A MOHOACTION file is an action document created with Anime Studio, which is a program used to create drawings and animations. It contains an action, which is a movement by an animation that can be applied to other animations with similar bone structures. MOHOACTION files replaced .ANIMEACTION files with the release of version 12 of Moho Debut and Pro.

MOHOACTION files are designed to help users share actions with other users and access favorite actions to apply to animations. You can create and open MOHOACTION files in the Actions window. To open the window, select Window → Actions. Click the "New Action" icon to create a new action or click the "Import Action" icon to open a MOHOACTION file. NOTE: Moho was formerly known as Anime Studio before the release of version 12.
