## What is FolderShelf?

Folder Image Viewer lets you browse the PDFs and images you keep in folders — on your
device or in the cloud — exactly as you filed them.

WHEN IT HELPS

• Technical PDFs and textbooks piling up in a folder, with no appetite for loading
  them into Books one volume at a time
• Photos exported from a camera, still sorted into the folders you made
• Scanned documents and drawings, opened per project
• Reference images and design assets, grouped by category

Photos organises by album, not by folder. Books wants each PDF registered
individually. Neither will simply open a folder.
This app does: pick one folder, and every PDF and image folder inside it lines up.
Nothing is imported.

WHAT MAKES IT DIFFERENT

• Nothing is copied
  Your images are never imported into the app. They are read in place, from wherever
  they already live. No duplicate storage, and reorganising your folders is reflected
  immediately.

• Your folder structure becomes the gallery
  Pick one source folder and the app finds every subfolder containing images and every
  PDF inside it, then lays them out one entry at a time. No adding them one by one.

• PDFs open as they are
  A PDF in your folder becomes a single entry — one file, one volume. Nothing is
  converted and nothing is imported into the app. Open it and turn the pages.
  Because PDFs are read through the same viewer as image folders, zooming, two-up
  view, and resuming where you left off all work the same way.

• Cloud friendly
  Alongside iCloud Drive, you can reference cloud services connected to the Files app.
  Only the cover is loaded up front; the rest download when you actually open a folder,
  so opening the gallery never triggers a flood of downloads.

• Fast search
  Search folder names and file names together. Results come from an in-memory index
  rather than rescanning storage on every keystroke, so it stays quick as your
  collection grows.

• A viewer that gets out of the way
  Controls stay hidden until you tap. Pinch to zoom, double-tap to reset,
  and switch to a two-up view when you want to compare side by side.

• Pick up where you left off
  Your position is remembered per folder and shown in the gallery, so even a folder
  with hundreds of images opens where you stopped.

• Sorting that behaves
  Order folders by number, name, or date. The order of images inside a folder always
  follows their file names, so sorting never scrambles their contents.

• Three languages
  English, 日本語, and 简体中文, switchable at any time in Settings.

SUPPORTED FORMATS

Images: JPEG, PNG, WebP

PRICING

Everything is free for 7 days after install. To keep using the app after that,
a single one-time purchase unlocks it permanently. No subscriptions, ever.

PLEASE NOTE

• This is a viewer and includes no books or images of its own — only a few samples
  for trying it out. Please use your own files.
• Password-protected PDFs are not supported.
• Because of an iOS limitation, some cloud services (such as OneDrive and Box)
  cannot be browsed in folder-selection mode. For those, use "Add Files"
  to select image files directly instead.
