Opening LOKF Files
The LOKF file type is primarily associated with Microsoft Office.
What is a LOKF file
LOKF files mostly belong to Microsoft Office. LOKF files have multiple roles depending on their source.
In many cases, these files are temporary lock files created by Microsoft Office programs. They use an internal ZIP format to secure a document during an active session and prevent editing conflicts. The file is normally removed when the application closes the document.
Sometimes, a LOKF file appears as a ransomware file extension where the internal format is similar to a JPG image. In these instances the file locks image content with encryption.
There is also a variant that uses an EXE format, acting as a locked executable file generated by security software like CheckPoint ZoneAlarm.If the file originated from Microsoft Office, let the program manage it rather than opening it manually. If you notice unexpected LOKF files especially during a suspected ransomware attack, run a full antivirus scan. For locked executable files, do not execute them unless you are certain they come from a trusted source.

How to open LOKF files

If you cannot open your LOKF file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a LOKF file directly in the browser:.

Programs that open and convert LOKF files:
- Microsoft Office
See the previous paragraphs to learn more about the main application. LOKF files are often referred to as Microsoft Office miscs because this type of file is primarily created or used by this software.
- Microsoft Office SuiteA .LOKF file signifies a locked file, typically associated with Microsoft Office applications. It serves as a temporary indicator that a file, such as a Word document or an Excel spreadsheet, is currently in use and prevents other users or processes from modifying it simultaneously. The presence of a .LOKF file helps avoid data corruption and ensures data integrity during concurrent access attempts. These lock files are automatically generated when a file is opened and are usually removed upon closing the file. However, under certain circumstances, such as an application crash or improper file handling, .LOKF files may remain, preventing access to the original file until manually deleted. This file format is classified as Temporary/Lock File.
LOKF 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 determined based on the file extension and the signature (the first few characters of a file). Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. If there are problems opening a file, you must first determine the file format used. Our examination of the LOKF files comes to the following conclusion:
The LOKF file extension is rarely used and is used by different programs with different formats. The file formats most commonly found in LOKF files are:
- 25% of all LOKF files use the ZIP algorithm, i.e. a LOKF file contains several compressed files. You can see the included files and images by renaming the file extension to .zip and then double-clicking it. The files are often between 13 KB and 1 MB in size. Files like these have the following tags: docx and xlsx.
- 25% of all LOKF files save the data in JPG file format. JPEG is the standard image format for lossy and compressed image data. These files contain neither text nor words, but only data. LOKF files can be up to 10 MB in size, but are often around 78 KB - 4 MB. The file name IMG_20180601.jpg.lokf is characteristic of these files. Such files are related to dscf.
The remaining 50% of all LOKF files are different files with different signatures, often, for example, PDF and EXE. Drag & drop your file here to see the file format and a preview of your LOKF file!
