I know it is possible to open more than one file by selecting the files, but if I have those different files in different folders and sub-folders, how can I get the whole text in one single editor file?
Thanks a lot!
In order to do that, you need to create your project and keep adding files using the "Add Files" command/button. Then, as you know, in "Files" view, you select the files you want to work on.
If you add your files, by adding entire folders using the "Add Folders" command/button, you cannot open files across folders, since Studio keeps you within one folder at a time. Please read below.
From SDL Trados Studio 2014 Help:
You can add files individually or you can add a folder structure. All of the files in the folder structure are added to the project. The New Project wizard creates a folder for every target language you have selected, and places the prepared *.sdlxliff files and any reference files in the appropriate language folder. If you selected files in a folder structure, this structure will be replicated in the target language folders.
Best of luck!
