What is a TCH file?

TCH files mostly belong to Total Commander.

The TCH extension does not refer to a single file type. Instead, it is used by different systems that serve separate purposes. If you have a TCH file, its content and method of opening depend on the program that created it.
Consider these common uses:

• Compressed Texture Format: This version is used by Total Commander to store compressed texture data. It is often linked to applications like Total War. For more details about Total Commander, visit the official site.
• OneTouch AES Encrypted File: Here, the file contains data encrypted using the AES algorithm. This format is produced by tools such as the OneTouch Data Transfer Tool, ensuring secure file handling.
• Tokyo Cabinet Database File: In this case, the file is part of the Tokyo Cabinet database system and holds structured data. More information can be found on the Tokyo Cabinet website.

If you are unsure which version you have, inspect the file header with a text or hex editor. Knowing the origin helps you open the file with the correct application. Use the relevant tool for graphical texture data, encryption/decryption, or database viewing.
FilExt.com tip: Each TCH file carries specific coding that suits its purpose, so matching it with its source software is key.

How do you open TCH files?

You need a suitable software like Total Commander to open a TCH 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. If you cannot open your TCH file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a TCH file directly in the browser:. Just drag the file onto this browser window and drop it.

TCH file format details:

If you can determine the file format, the associated program can also be determined. Each file format has a unique extension and almost always a unique signature. For example, Microsoft Word documents have the extension .docx and the signature (usually the first 3 characters in this file) PK. Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. Exact knowledge of the format is therefore important in order to solve problems occurring in files. Our evaluation of the TCH files looks like this:
