FolderShelf: PDF & Images
MASAYOSHI SUGIMOTO
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 Documents: PDF 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.
