Quick answer
As bookmarks and reading history grows, keep active books separate, remove true duplicates, and rely on search instead of adding endless folders.
Too many bookmarks can become as hard to scan as the whole book.
Separate active and archive items
Keep current books visible. Move finished or rarely used items into an archive group.
This reduces the number of choices when you simply want to continue reading.
Keep one main copy
Duplicate files can split progress, bookmarks, and notes.
Keep one main reading copy and a clearly separate backup.
Review storage
Large images, comics, PDFs, and downloaded voice models can use storage quickly.
Remove items you can safely restore later, but do not delete the only copy of an important file.
Use search before more folders
If you can find a title in seconds with search, another folder may not be necessary.
Simple systems are easier to remember after months of use.
