Nokia Series 40 And 60 Theme Format | Nokia | Misc Files |
The NTH file is an implementation of the Nokia Series 40 Theme File format. Introduced in 2005 and primarily used by Nokia, this file type is generally associated with mobile phones and allows for the customization of both hardware and software elements within those devices.
The file carries a wide range of data types, including images, sounds, Java applications, and text. For example, the NTH style sheet contains parameters such as font size and color selection which can be changed in the file. Additionally, menu icons and wallpapers can also be customized in a native NTH file format. Files in this format have the ability to interact directly with the server, allowing for a more sophisticated level of customization.
Data Format
Data stored in Nokia Theme Files (NTH) is represented in the XML, BMP, JPEG, GIF, PNG, WAV, and MIDI formats. These files contain all of the necessary information for applying themes to Nokia Series 40 devices. Specific features of the file include multi-layer support, multilingual support through an internationalization layer, and content encryption. The Multi-item Plate Supporting (MIPS) layer ensures that themes maintain integrity regardless of device configurations.
Similar File Types
NTH files are related to two additional file types: MKT files, which stands for “Mobile Theme Application”; and MTE files, which stands for "Mobile Theme Editor". They are both associated with Nokia’s softwares used to help customize third party applications designed for Nokia devices.
Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .NTH) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .NTH extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .NTH file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .NTH extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .NTH extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .NTH file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .NTH file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .NTH file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .NTH file) will be extended to the maximum.
It is also good to check
- if the .NTH file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
