Issues Opening DRO Files

DOSBox Isn't There

When you double-click your DRO file, you may see a dialog box from your operating system stating that it "Cannot Open This File Type". If so, it typically means that you don't have DOSBox installed for %%os%%. This will prevent you from double-clicking to open the DRO file because the OS doesn’t know how to handle it.


Tip: If you have another software that you know opens DRO files, you can select it by hitting the "Show Apps" button.


Obsolete Version of DOSBox

In other instances, your DOSBox Raw OPL Format file version may not be supported by your version of DOSBox. Installing the latest version of DOSBox from Open Source is recommended. Most of the time your DOSBox Raw OPL Format file was created by a newer DOSBox than what you have installed.


Tip: Sometimes you can get a clue about the version of DRO file you have by right clicking on the file, then clicking on "Properties" (Windows) or "Get Info" (Mac OSX).


Summary: In either case, the majority of problems opening DRO files are related to not having the correct software application installed on your computer.
