While using the Creative Cloud Packager to assemble a package, the software downloads all necessary files. But it downloads them not directly to the chosen location, but to somewhere on the operating system disk.
But I have my operating system on a 64GB SSD, of which already >55 GB is used. So, CC Packager does not have enough space to store all files. As a result I can't assemble a package.
IMHO the Packager should use the assigned drive/folder also for temp files, not the OS disk.
