What is an NTH file?

NTH files mostly belong to Nokia Theme Studio. NTH files serve as theme packages for Nokia Series 40 devices. Internally, they are built as ZIP archives that bundle all the resources needed to customize a phone's appearance.
Inside an NTH file you may find:

Graphical assets such as icons and wallpapers

XML configuration files that define layout settings

Font and style files used for user interface text

FilExt.com note: This structure allows Nokia Theme Studio to easily apply and edit themes on supported mobile devices. You can also open an NTH file with a common archive tool to inspect its components, but for modifications and proper theme application, using Nokia Theme Studio is advised.

How to open an NTH file

You need a suitable software like Nokia Theme Studio to open an NTH file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert.

To view or edit NTH files you need to know the file format, because it determines how the data in this file is stored. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). If the file extension or signature does not match the file format, errors will occur when opening or editing the file. If there are problems opening a file, you must first determine the file format used. Our evaluation of the NTH files is as follows:
