LightDrive offers two ways to read stored material.
Files
Select a supported document in Files to open its native viewer. Text files open read-write in the Text app when they are ordinary documents. Images, video, PDF, and other supported formats open in their corresponding viewers.
Books
The Books app provides separate ebook and audiobook shelves, dedicated Books and Audiobooks folders, public-domain catalog search, imports, metadata, progress, collections, notes, and reading or listening controls. A plain-text file opened from the Books shelf is read-only, which prevents accidental edits while reading.
Use Files to manage arbitrary documents. Use Books when the item belongs in a reading or listening library.
