Having problems opening an UIS file?

We have programs that open, view or play your UIS files.

Opening UIS files

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

What is a UIS file?

Every day thousands of users submit information to us about which programs they use to open specific types of files.

While we do not yet have a description of the UIS file format and what it is normally used for, we do know which programs are known to open these files. See the list of programs recommended by our users below.

We are constantly working on adding more file type descriptions to the site - the current count exceeds thousand by far, and more information about UIS files will hopefully be added soon.

Try a universal file viewer

Try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and most likely yours too. Download Free File Viewer here.

About File Extension UIS

File.org aims to be the go-to resource for file type- and related software information. We spend countless hours researching various file formats and software that can open, convert, create or otherwise work with those files.

If you have additional information about the UIS file format or software that uses files with the UIS suffix, please do get in touch - we would love hearing from you.
