I found the solution:

Put the file you want to add in a specific folder and then use the method "addFolder()".

All files within this folder will be added and if the same named folder is already in the zip, your folder will not be re-created, but the files will be added to the existing one

Example:

ZipFile zipFile = new ZipFile(source);
ZipParameters parameters = new ZipParameters();

zipFile.addFolder(new File("C:/Users/XXXXXX/Desktop/HELLO_Folder), parameters);
