Is it possible to open a file retrieved from a show controller in Winscript?
If you did not originally download the readable version of the script, called the 'archive' then there is no way to upload a readable version of the original script.
The DAT file is a compiled version of the script, and there is no way to retrieve the original script from this compiled version. When you download a show to your controller, you can also (with WinScript 2.0) download an 'archive' of the script which can then be uploaded and edited later. To do so, use File - Upload Script from Unit.
