Why is there an additional directory level between my ctfroot and the files I include with my compiled application?

I have created and deployed a compiled application using MATLAB Compiler. When I run the application on the target machine and examine the location of the CTF root:

C:\Users\UserName\Desktop\Temp\mcrCache9.7\AppName1

I see that this folder does not contain the files I included when packaging my app using MATLAB Compiler. Instead, I see the following directories:

.matlab

.MATA

AppName

AppName_5F4C30D8E7FC4C9362D4D35FA80E3C3E

toolbox

.created

The folder which actually contains the files I included with my application is "AppName" (full path C:\Users\UserName\Desktop\Temp\mcrCache9.7\AppName1\AppName).

However, I've done this with several applications and notice that the name of this subdirectory is not always the same as the name of my project (sometimes it is a shortened version). There doesn't seem to be any way to predict the name of this folder.

In previous versions of MATLAB (R2018a and earlier), this additional subdirectory did not exist. Is this expected?

This behavior is expected, and is a change which was introduced in R2018b.

Any relative pathing used within your compiled code will still work.

Dear Support Team

Can you please take at look at this and throw some light on what is going on there.

MW tech support, at least in this region, do not honour their legal commitments of supporting installation issues with compiler/compiled products on perpetual licences without up to date on maintenance. This is is not even an installation issue, I'm certain it would be waste of time.
