What is an ATTHEME file?

ATTHEME files mostly belong to Telegram.

ATTHEME files are configuration files used to adjust the look and feel of Telegram applications. They store settings that define colors, fonts, backgrounds, and other interface properties for the app.
These files serve mainly two use cases:

Telegram Desktop: Most ATTHEME files load in Telegram Desktop. You can import them via the app’s appearance settings. For more details, visit the Telegram Desktop website.
Telegram Android: Some ATTHEME files are used on mobile devices as theme files. See more at Telegram Themes.

FilExt.com tips: The files use a proprietary format. They are read by the Telegram client to apply a new visual scheme without affecting your data. You can view or edit them with a text editor, but caution is advised. Tip: Always back up your file before making changes.
