Every Database in Caché or IRIS has a "NickName" (TEST, APP, USER, *TEMP, ..)
The file location is just a pointer related to the location of the file used
Similar Resource is an attribute to this "NickName".  and NOT to the related file
Changing it affects user access, but doesn't care at all about the file location.
The *.DAT file has no information about Resources or its NickName.  

Way back in the past, when file sizes were limited by file systems, there were
"Continuation" Files for Cache.DAT. Those knew the starting Cache.DAT.
But this is decades back and gone and doesn't exist anymore. 

Hi @Evgeny Shvarov,

I run my Docker Desktop on WIN10 
And with my setup, I have reviewed more than 300 Docker build sequences

Always focused on how easy it is for the average consumer and how well the description fits reality.
This package forced me to exercise settings that were just not needed before
And (differently from others) there is not the slightest signal in the description of that requirement.
It's some *KIT*  stuff and the official doc doesn't care much about WIN.
it finally moved along. and others should be warned [getting rid of it was another story]
And the result was something that I see multiple times daily in my SMP instances.
Sorry!

Nice screenshots from VSCode.
Just to be clear: I tried but will never use VSCode as long as I have my Studio available.
And I never touched it in any of my reviews or other situations.
