Avoid MCR CACHE deletion each time an executable is launched

Hi Everyone,

I have two Matlab scripts (Init.m and Filter.m) compiled using the Matlab application compiler in Windows (Init.exe and Filter.exe are created). I have seen that if I launch the Init.exe, a folder is created in the MCR_CACHE folder containing all the necessary files to run Init.exe. If I launch Init.exe again the time to execute it reduces dramatically since its folder in MCR_CACHE folder has already been created. Now, if I launch the Filter.exe, the folder of the Init.exe in the MCR_CACHE is deleted and a folder for the Filter.exe in the MCR_CACHE is created. How can I avoid the deletion of the Init.exe folder in the MCR_CACHE? This way if I launched Init.exe after having launched the Filter.exe, the Init.exe execution would be much faster.

"Now, if I launch the Filter.exe, the folder of the Init.exe in the MCR_CACHE is deleted and a folder for the Filter.exe in the MCR_CACHE is created"

How can you do that? MCR cache are stored by application and they should not delete the others (unless your cach run out of space)

In windows, it locate somewhere here:

C:\Users\XXX\AppData\Local\Temp\XXX\mcrCachea.b\Filter_yyy

C:\Users\XXX\AppData\Local\Temp\XXX\mcrCachea.b\Init_zzz

From my experience, there is no reason they delete each other.

The deletion is an automatic process: as soon as I launch the Filter.exe, the Init folder in the MCR_CACHE is deleted. They are two separated files and I launch them one after the other. When I lauch the second, the Init folder is deleted. How can I avoid that?

I have exactly the same problem. How did you resolve it ?

@MetierSI try to move MCR cache root folder to a place where OS does not clean automatically
