In order to view files on your mobile phone, install myCloud on your mobile phone. The myCloud app is offered for Android and iOS devices. Through the app, you have access to all the files from your computer that you have synchronized with myCloud.ch via myCloud Desktop.
myCloud does not support direct editing of files. If you still want to edit files on your mobile phone, you will need an appropriate app with which you can edit the particular file type (for example Microsoft Word)
