How to open DCU files

Did your computer fail to open a DCU file? We explain what DCU files are and recommend software that we know can open or convert your files.

What is a DCU file?

We know of 2 different uses of the DCU file type, one of them being Borland Delphi 6 Library. Read the details below.

The DCU file extension indicates to your device which app can open the file. However, different apps may use the same file extension for different types of data. So a DCU opener may not be able to open all kinds of DCU files. In this case, look through both formats to make sure you find the best suited DCU viewer.
