How to see target files etc. in Windows Explorer

I was sent a project containing a number files by a client and have imported and translated the files.

I have saved the completed files with "save target as" and would now like to open them in Word.

When I save the files with "save target as", it said that the target file was saved in a subfolder called DE-de in the project folder.

However, when I look at the project folder in Windows Explorer it only shows me the project folder, no subfolders.

How can I get to and open the Word target files?

Thanks.
