Opening ACTHEME files
Did your computer fail to open an ACTHEME file? We explain what ACTHEME files are and recommend software that we know can open or convert your ACTHEME files.
What is an ACTHEME 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 ACTHEME 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 ACTHEME files will hopefully be added soon.
Software that will open, convert or fix ACTHEME files
Try a universal file viewer
In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
