What is a DMF file

DMF files mostly belong to DMF Viewer. The DMF extension is used in several specific ways. It may be a Data Mining Format file that stores structured data for analysis. Such files are often managed with a DMF Viewer and linked to tools like the Deluge Mod Tracker module (Delorie).

Deluge Music Format: These files use zlib compression for audio data and are supported by programs such as Deflemask (Deflemask).

Data Miner File: Created by iMacros, these serve as macro files for traffic automation and are associated with tools like Xrumer; more details can be found on the iMacros site.

Deleted Media File: This variation employs Microsoft Compound file architecture to store deleted file fragments, often handled by Disk Masher File Splitter and backup utilities such as Dell DataSafe Backup and Restore.

FilExt.com note: Examine the file header or source to identify which variation you have, then use the corresponding program to open or manage it.

How to open a DMF file

DMF file extension format:

A file format defines how the data in the file is structured. 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 DMF files comes to the following conclusion:

DMF is seldom used as a file extension and includes different formats for different programs. The following file formats are most commonly found in DMF files:

40% of all DMF files start with the magic bytes DMF, which are always the first bytes of this file format. The content consists of illegible binary data, which can only be read and interpreted by the associated programs. The file size is in the range of 20 KB to 820 KB. It is a modern file type. Several words can almost always be found in the files, e.g. DMF Version 1.10 C.
10% of all DMF files start with the magic bytes [INFO], which are always the first bytes of this file format. The contents of these files are easily readable with a text editor. The files are 420 bytes to 880 bytes in size, with a median of 660 bytes. The keywords Description, [INFO], Var_A_Tab="Instructions", Var_A_Text, Visit, Click, Insert, URLs, Var_A_Tab="URL List", Var_B_Tab="Referer (Optional)", Var_B_Text, facebook, least, minimum, number, seconds and want are typical for these files. A usual file name is 2_Random_Clicks.dmf or Simple_Visit.dmf. Such DMF files store data about clicks, random, simple and visit.

All the rest of the DMF files (50%) have different formats, such as D-Lusion Music Format module, zlib and DOC. You can get all the details of your DMF file by dragging it onto this page or by clicking the button "Choose your .dmf file to analyze" above.
