Test if the zip-files are decompressed

I would like to recover the name of a decompressed folder and know if it has really been decompressed.
I open the folder where the folders I am going to examine are located and for each folder I do this command: “file.EndsWith(“zip”) = True”.

But when I count the number of decompressed folders with “Directory.getfiles(strFolder).Count”. It returns zero. This implies that the robot does not enter the for schleife.
However, when I open the folder on my desktop, the unzipped folders are there.
Has anyone ever had to solve this type of problem?
