Since there is always a copy of each file you save in myCloud located on your hard drive, myCloud Desktop takes up the same amount of storage space as is being used at myCloud.ch. For this, you’ll need at least 1 GB of free storage space on your computer.
Should you not have enough storage space available on your hard drive in order to save all files located at myCloud.ch, there is no need to delete any files from myCloud.ch. You can use selective synchronisation to exclude certain folders from synchronising. Alternatively, you could also change the storage location of your myCloud folder.
Should you still not have enough available storage space on your computer, you can always upload your files using the web interface at www.mycloud.ch.
