I have a Macbook Pro and recently purchased a new IPad Air (IOS 14.7.1). qtVlm work fine on the Macbook Pro but I would like to use it also on the IPad. Installation of qtVlm to the IPAD worked fine. However, I ran into problems trying to load charts. After connecting the Ipad to my Macbook I can see the respective file folders (for charts) the iOS App of qtVlm is using by using Finder. Since Apple is no longer using Itunes to transfer files but Finder, I have opened two Finder windows on the Macbook that show both my source files and the folders on the IPad. However, I have been trying, unsuccesfully, to transfer files (e.g. vector charts, harmonics files) into the respective folders on the IPad. Using copy and paste or drag and drop I can put the files on the Ipad but only at the hirarchy level where the qtVlm folders themselves reside, i.e., I cannot add the files into the folders, where they belong. Any advice what I might be doing wrong or what I should try instead? Thanks!
