Apple's Files app is its mobile version of iCloud Drive - similar to Dropbox or Google Drive - but with a difference - photos, pdf documents, and html web pages can be stored in named Folders and Sub-Folders - and viewed while using Tidy Health. If Files app is full, then data is encrypted and moved to Apple’s remote iCloud servers.
Your Files manager is Tidy Files. Your uploads are organized and integrated inside designated galleries - Documents / X-rays / Labs - so you can more quickly find what you seeking. Whenever files are added in another place (such as Vaccinations), they are duplicated and saved in one of the Tidy Files galleries.
