File extension dif is mainly known for its use for spreadsheet files saved in Data Interchange format.
Data Interchange Format, also known as Navy DIF, is a text file format used to import/export single spreadsheets between spreadsheet programs (OpenOffice.org Calc, Excel, Gnumeric, StarCalc, Lotus 1-2-3, FileMaker, dBase, Framework, Multiplan, etc.).
The .dif file is a workbooks, with the limitation that single workbook contains only single spreadsheet. These files were originally used by VisiCalc.
Most current spreadsheet programs are able to work with .dif files, or at least import the data.
Whilst DIF spreadsheets were mostly used in the past, some programs still support it and can import data from them.

Diff is a file comparison utility available on Unix and Linux systems. It compares two files, or a current file with an earlier version, and reports the changes needed to transform one into the other.
The output usually describes changes line by line for text files. Implementations can also detect or handle binary files, although a binary comparison generally does not produce a useful line-by-line patch. The resulting text is commonly called a diff or a patch.
A dif file is a script-like change description rather than a complete copy of either source file. The Unix patch command reads it and applies the recorded changes to the appropriate original file. Similar output from other comparison utilities is also commonly called a diff, and "diff" is often used as a verb for calculating differences.
A dif file is normally opened as plain text. A text editor can display its contents, while the Unix or Linux patch command can apply the recorded changes to the matching source file.
To inspect the file, use the command line with standard Unix tools such as diff and patch. The file may also be opened in a source-code editor that supports diff or patch text.
A dif file is already a text description of file changes, so it normally has no useful conversion to another file format. To produce a different diff representation, run diff again with the required options.
To turn the changes into an updated source file, apply the dif file with the Unix or Linux patch command. The original file should correspond to the file against which the patch was created for the changes to be applied correctly.

The dif file extension used for DVCPRO or DV video file.
Digital Video (DV) is a digital video format launched in 1995, and, in its smaller tape form factor MiniDV, has since become a standard for home and semi-professional video production; it is sometimes used for professional purposes as well, such as filmmaking and electronic news gathering (ENG).
The DV specification defines both the codec and the tape format. Features include intraframe compression for uncomplicated editing, a standard interface for transfer to non-linear editing systems (IEEE 1394, also known as FireWire), and good video quality.
The dif file stores video data.

OS/2 was developed by IBM and Microsoft and was later maintained exclusively by IBM. The operating system uses this file to store display information data.
OS/2 is no longer developed, and support was discontinued in 2006.
This is an OS/2 system file rather than a document intended for direct use. OS/2 should read it as part of the system configuration; it generally cannot be meaningfully opened in a standard Windows, macOS or Linux application.
There is no usual conversion for an OS/2 display information file. Its data is intended for use by OS/2, so it should normally be retained in its original form rather than exported to another format.
