In VB6, what is the .frx file used for?

Question

Each .frm file has a binary .frx file associated with it. What is it for?

Answer 1

\An .FRX file is a binary data file used to store binary information for the form (.FRM) file with the same file name.

Some controls, such as the PictureBox and Image controls, have properties that use binary data as their values. Visual Basic stores the binary data in an .FRX file with the same file name as the Form file. The .FRX file is a proprietary format.

If your project contains .FRX files, you should include these files with the corresponding .FRM files. A form containing binary information but lacking the associated .FRX files will not function correctly.
