What is a DLK file?

DLK files mostly belong to Windows / DATEV DMS. A DLK file may not be what it seems at first glance. In many cases it is a keyboard layout file that comes in the form of a compiled Windows executable (EXE). When used this way, the file is designed to install or change a keyboard configuration on a Windows system and is often associated with Dietrich's Lexikon.
Alternatively, a DLK file can be a document link file. In this use, the file acts as a pointer within a document management system. This version is commonly used by DATEV and is integrated with their DMS environment. For more details on this application, you can visit the DATEV website.
When working with a DLK file, keep these points in mind:

• Check the file’s properties to see if it’s an executable or a link file.
• If it’s an executable, run it only if you trust the source.
• If it’s a document link, open it using the appropriate DATEV software.
• Be aware that the same file extension can hide very different file formats.

How to open DLK files

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

DLK file format details:

Every file has a defined file format, i.e. how the data is arranged in the file. The file format can be deduced from the file extension and the signature. If the file extension does not match the file format, double-clicking on the file will cause an error upon opening. When there is a problem with a file, the first step to solving it is to determine the file format. Our evaluation of the DLK files looks like this:

The file type with the extension 'DLK' is used by different programs with different formats. However, the following two file formats are common:

• 60% of all DLK files start with the bytes [InternetShortcut] crucial for this file format. The contents of these files are partially readable with a text editor. The average file size is 180 bytes with most files being between 64 bytes and 180 bytes in size. The file type is very recent. Certain words are almost always found in the files, such as [InternetShortcut]. Such files sometimes refer to bescheid, rung, fung, vorgangsmappe, belege, bvfa, unterlagen and erkl.
• 25% of all DLK files are based on the well-known EXE file format. EXE is the abbreviation for executable and is the standard executable file format on Windows. The format can be identified by the letters "MZ" at the beginning. Executable files can also be used to distribute viruses and other types of malicious software (malware). They consist of unreadable binary data. A typical file size is 2 MB. The keywords !This program cannot be run in DOS mode are typical for these files. A common filename is pcmacv.dlk or pinput.dlk. Such files sometimes refer to ptcrmv and pcmac.

All other DLK files (15%) have no consistent format. These files are often connected to bersendung, rechnung, fibu, lohn, aktenvermerk, auswertungen, sonstige, vertrag or nicht. If you want to find out what your DLK file contains, drag and drop it onto this page.
