SafeViewer – Encrypted File Explorer for Windows
Keep your private files encrypted and still open them in one click. SafeViewer is a secure file explorer: browse your PC like a normal file manager, encrypt any file with AES-256, and open images, PDFs, text and Office documents — all decrypted only in memory, never written back to disk. Your original files and their readable contents never leave your machine.

All-new in 2.0 — a complete redesign
SafeViewer 2.0 is a ground-up reconstruction with a modern light/dark interface. The old fixed vault is gone — you now browse any drive or folder, with the list filtered to show only your encrypted files. Add files or whole folders, preview them inline or in a maximizable viewer window, and right-click to view, export or delete. Authenticated AES-256 encryption protects every file, and your originals are never touched.

🗂️ Encrypted-File Explorer
Browse any drive or folder on your PC just like a normal file manager — with a location dropdown, clickable breadcrumb, list / grid views and search. The list is filtered to show only your encrypted files plus folders to navigate.
🔒 AES-256 Encryption
Every file is protected with authenticated AES-256, with a key derived from your session password and unique encryption data per file. Tampering with an encrypted file is detected the moment you open it.
➕ Add Files & Add Folder
Drag & drop files, or pick a whole folder (with an include-subfolders option), and encrypt them in place or into the folder you're browsing. A completion summary reports what was encrypted, skipped, or already protected.
👁️ In-Memory Viewers
Open images, PDFs, text / code, Excel, Word and PowerPoint in a built-in viewer — single-click to preview, double-click for a maximizable window. Images and PDFs support mouse-wheel zoom and drag to pan. Nothing is ever written to disk.
🖱️ Right-Click Actions
Right-click any encrypted file to View it, Export un-encrypted a decrypted copy to a location you choose, or Delete it — with protected OS locations refused as a safeguard.
⭐ Quick Access
Pin folders to Favorites and jump straight back to them, and reopen your Recent Files in one click. Both lists are remembered between sessions.
🛡️ Your Originals Stay Yours
SafeViewer never deletes your un-encrypted originals — that's up to you — and decrypted content only ever lives in memory while you're viewing it. No telemetry, no cloud, nothing leaves your machine.
⚙️ Settings & Themes
Choose a System / Light / Dark theme, pick which folder the explorer opens in after every unlock, and decide whether to encrypt only images and documents or all file types.
♻️ Opens Older Files
Files from the previous SafeViewer version appear in the list automatically and open with your session password — and if an old file used a different password, SafeViewer simply prompts for it and retries.
