What is the best data recovery software for deleted files on iMac
Due to an entire 300GB file archive disappearing without trace off iCloud I am desperately clutching at data recovery to retrieve any amount of my files. They sat in a folder on my iMac HD before uploading them to iCloud so a recovery of 'deleted' files would be preferred and recovered with original file names intact preferably. It included 20 years of Quark and Indesign based projects with linked images so any necessity for identifying and relinking each file would be an absolute nightmare. Unrelated to this is my treatment by Apple Customer Care who have shown little to no care nor volunteered a single call to update me in 3 weeks of waiting.
iMac (27-inch, Late 2013), OS X Yosemite (10.10.3), Also iPhone
