What is an IDK file

IDK files mostly belong to ESRI ArcGIS Pro. The IDK file is a container that uses the ZIP format to compress an XML document.
Key Details compiled by FilExt.com:

Data Format: It holds structured data in XML, compressed to save space.

Primary Use: Mostly used as a Mobile Device Backup file.

GIS Application: It can also be tied to ESRI ArcGIS Pro workflows.

FilExt.com tips: The XML inside can be inspected after extraction with common ZIP tools. This makes it possible to view backup or configuration data directly. Use a file archiver (like 7-Zip) to open and explore the content if needed.

How to open an IDK file

You need a suitable software like ESRI ArcGIS Pro to open an IDK 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 IDK file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a IDK file directly in the browser:. Just drag the file onto this browser window and drop it.

IDK file format:

Every file has a defined file format, i.e. how the data is arranged in the file. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). 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. When there is a problem with a file, the first step to solving it is to determine the file format. Our examination of the IDK files comes to the following conclusion:

IDK is not a common file extension and includes different formats for different programs. The two most common formats are as follows:

55% of all IDK files use the ZIP algorithm, i.e. an IDK file contains several compressed files. A typical number of included files is 1. Tip: If you rename the file ending to .zip and then double-click it, you see the included files and images. Most of these files are 500 bytes to 560 bytes in size. The files contain the following words: xmlm.
5% of all IDK files start with the bytes KARALIST0001, which are crucial for this file format. These files are binary files, so they do not contain text, but only cryptic characters. A typical file size is 3 MB. The files contain the following words: KARALIST0001. The following filename is common: SongList.idk.

The remaining 40% of all IDK files are different files with different signatures. They are often associated with xlnt. You can get all the details of your IDK file by dragging it onto this page or by clicking the button "Choose your .idk file to analyze" above.

How to solve problems with IDK files

Associate the IDK file extension with the correct application.
Update your software that should actually open backup files. Because only the current version supports the latest IDK file format. Search, therefore, e.g. on the manufacturer website after an available ESRI ArcGIS Pro update.
To make sure that your IDK file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
