Impossibility to save the package into the folder I want (Studio 2014, idem for Studio 2015)

My first question is why I am non able to export the package into the folder I want for my new client. Studio 2015 (as before Studio 2014) is so obstinate and impose on me only the previous folder: that of my other client. When I indicate to Studio 2015 the NEW folder for my NEW package of my NEW client, the Studio message to me that the folder already contains the folder inviting me to CHOOSE a NEW or EMPTY folder. But the PREVIOUS folder (that of my old client) is neither new nor empty.

My second question is when I succumb to fight with Studio 2015, and I let it to save the package of my new client into the folder of my old client, this "main" folder contains the subfolder of new package with all the subsufolders as usual. BUT when I satisfy the Studio 2015 and give him the "NEW or EMPTY" folder, I find in this new folder only the subsubfolders of new package. That means Studio 2015 does't respect, in this new main folder, the normal structure of package (that means: folder/subfolder with the name of the package/subsubfolder of package - languages/packages/reports/tm + the file sdlproj).

This structure is respected only in the folder prefered from Studio: WHY????

Thanks for any kind idea how customize the Studio 2015.
