What is a SUPP file?

SUPP files mostly belong to Xcode. SUPP files are used within the iOS app environment as supplemental resource files. They are stored with the app and managed by development tools like Xcode.

Support Role: They contain extra data required during an app’s runtime.

Backup Functionality: Some SUPP files hold encrypted backup data for apps, a method also detailed by Deciphertools.

FilExt.com tip: These files are not meant to be opened or edited directly. They are handled automatically by the system and development tools to ensure proper functioning of iOS applications.

How to open SUPP files

You need a suitable software like Xcode to open a SUPP 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.

Xcode, iOS applications
A .SUPP file is a supplemental file used by various applications, primarily on Apple's iOS platform. In the context of Xcode, it's a supplemental resource file containing additional data or assets required by the app. It can also appear as an encrypted supplemental data file when backing up iOS app data. The specific format and content of a .SUPP file depend on the application that created it. This file format is classified as Supplemental Resource File.

SUPP format details:

Why is it important to know the file format? This is the only way to find out which program to use to open the file. The file format can be determined based on the file extension and the signature (the first few characters of a file). However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened. So a detailed analysis of a file is vital in order to determine the format and the associated program. Below is our analysis of the SUPP files:

SUPP is rarely used as a file extension and includes various formats for various programs. The following file formats are most commonly found in SUPP files:

40% of all SUPP files start with the bytes 01 35, which are crucial for this file format. They consist of unreadable binary data. The file size is in the range of 1 KB to 170 KB. It is a modern file type.
10% of all SUPP files use the same file format, which can be identified by the letters "01 33" at the beginning. The content consists of illegible binary data, which can only be read and interpreted by the associated programs. Most of these files are 7 KB to 220 KB in size.

The remaining 50% of all SUPP files are different files with different signatures. These files sometimes refer to network, support or unifi. You can get all the details of your SUPP file by dragging it onto this page or by clicking the button "Choose your .supp file to analyze" above.
