Photoshop: Hidden folder taking up 430 GB on HD

I've been using CS6 since 2013 on my MacBook Pro. I'm working on my 3rd eBook in iAuthor and edit photos to drop in (it will take .psd format, which is really nice). In early June, I was suddenly getting messages that my start up disk was almost full. When looking at the storage there was about 430 GB attributed to "other," which on one could explain (local Mac store). Searched for viruses/malware, nothing found. Tried moving everything non-essential off to external drives with not much GB freed-up. Cleared caches, not much space freed up. So I wiped my HD, then reinstalled software. Almost the entire HD available after the wipe. I kept everything on external drives except the software and the book project. 

Not two weeks later the same problem occured and almost couldn't save the iAuthor book file that is about 7GB. A web search of what's taking up my HD led me to download DaisyDisk app which found a hidden file with .cs in the name path 430 GB in size on my HD, but not able to enter the file or clear it. So, I wiped the HD again. It appears to be a hole or missing patch in the cs cache is the best I can figure? I'm afraid to reinstall PS again without more information, but I need it to do this job. I'm a student and can't afford to go to creative cloud, and I want to stay on CS6.

I'm now on MAC OS Sierra 10.12.5 with the last wipe and install. Should I set up external scratch disks to solve this? Limit the caching? I've been researching as much as I can, but I'm not sure what to do. I just found out about the purge feature, which I hadn't tried before. But the hidden folder is a concern, especially since it seems to be involved somehow. 

I admit that I recently started editing the photos with 10 or so photos open at one time, the Word document associated with the book chapter that has drafts of the photos edits open, and iAuthor open all at the same time. That way I can edit a chunk of photos and then drop them in the book. As soon as the photo portion of the project is finished, I'll be doing video edits in Premiere CS6. I never ran into this before. Help please!

How do you know that Photoshop is creating this file? What is the actual path to the file? I don't believe the file is one that we're writing.

Thank you. I'll look into chunk storage.

Yes, it seems to be an iAuthor and OS interface issue. I'm so relieved there is a work around for it. I really appreciate your help. I can't tell you what a relief it is, because I use my CS apps all the time and I really need them!

Cool. If I'm reading it correctly, macOS is probably saving a version of each of your iAuthor saves of that 7GB file. So each time you save it, it saves a new version under the hood.

Yes that seems to be what's going on. It looks like it started in OS 10 Lion version, but whatever patch they had must not be working with the latest version of Sierra. At least I can work with Apple to clear that folder when it reappears after I reinstall iAuthor and start working on the book again. Thank you so much again! You totally saved my life!!!
