Olympus View — WiFi File Manager for Olympus & OM System Cameras
Manage, download and delete photos on Olympus and OM System cameras via WiFi — from your phone or computer. The free OI.Share alternative that actually works.
Why not OI.Share? Olympus View vs OI.Share
The official Olympus OI.Share app has serious limitations. Olympus View — the open-source OI.Share alternative — solves them:
- Delete files from camera — OI.Share cannot delete photos
- Batch download by date — OI.Share only allows one by one
- Background downloads on Android — keep transferring with the app minimized or screen off
- Downloaded-file markers — see what was already copied even after restarting
- RAW/ORF filter — OI.Share shows all duplicates
- Works on Windows and in browser — OI.Share is mobile only
- Open source — OI.Share is proprietary

Features
QR Code Scanning
Scan the QR code from the camera screen — the app connects to WiFi automatically. Supports OIS1 and OIS3 formats.
File Deletion
Select unwanted files and delete them directly from the camera. Free up memory card space without a computer.
Select by Date
Select one file and press the button — all files from the same date are selected automatically.
File Type Filter
Choose RAW only, JPG only, or RAW + JPG. The selected mode is remembered between app launches.
Batch Download
Download groups of files with progress. On Android photos appear in gallery immediately.
Background Download
On Android, transfers keep running while Olympus View is minimized or the screen is off. Progress and completion are shown in system notifications.
Already Downloaded
Successfully transferred files get a persistent green marker, so you can reconnect days later and immediately see what was already copied.
Multi-platform
Works on Android, Windows and in any browser. Unified interface across all platforms.

Frequently Asked Questions
Can OI.Share delete photos from an Olympus camera?
No. The official OI.Share app cannot delete photos from your Olympus or OM System camera. Olympus View fills this gap — it supports direct file deletion from the camera memory card via WiFi.
How to delete photos from an Olympus camera via WiFi?
Enable WiFi on your camera → connect with Olympus View via QR code (Android) or direct WiFi (Windows/Web) → long-press a photo to enter selection mode → tap the delete button. Files are removed directly from the camera.
Is there a Web build?
Yes. Download the Web ZIP, run the web build in a browser, and connect the PC to the camera's WiFi network. No native desktop installer is required.
Technical Details
Stack
Flutter 3 / Dart — Material 3 — OPC Communication Protocol
Camera Protocol
The app communicates with the camera via HTTP over WiFi (IP: 192.168.0.10). Uses the OPC (Olympus OPC Communication Protocol).
QR Decoding
Olympus and OM System cameras use a proprietary QR code format (OIS1, OIS3) with a substitution cipher. The app decodes them automatically and extracts WiFi SSID, password and Bluetooth info.
Changelog
v1.3.13 — September 28, 2026
Video previews, persistent cache & reliable Android video downloads
- First public release after v1.3.11 — includes the v1.3.12 development changes plus the final video fixes completed for v1.3.13.
- Camera videos (MOV, MP4, M4V, AVI, MTS and M2TS) remain visible independently of the RAW/JPG still-photo filter.
- Higher-quality movie previews use the camera's
get_screennail.cgifirst-frame JPEG instead of stretching the small thumbnail whenever possible. - Movie screennails and the low-resolution thumbnail fallback are persistently cached, so video previews are not downloaded again on every gallery visit.
- Preview requests survive Android background/Wi-Fi changes and retry interrupted camera requests instead of leaving broken tiles.
- The persistent preview cache now keeps up to 1000 entries.
- Foreground and background movie downloads on Android use MediaStore.Video with the correct MIME type.
- Background download history is committed before completion and refreshed once more in the UI, so successful videos — including the last item in a batch — receive the persistent green downloaded marker.
- Build stack: Flutter 3.47.5 / Dart 3.13, Gradle 9.3.1, AGP 9.1.1, Kotlin 2.4.20, Java/Kotlin 17, compileSdk 37 and targetSdk 36.
- Version: 1.3.13+22.
v1.3.11 — September 20, 2026
OM-1 preview compatibility & faster full-screen viewing
- Fixed OM-1 gallery preview compatibility — v1.3.10 requested unsupported resize size 480; the grid now requests the camera-supported 1024 px resize preview.
- The small 160×120 thumbnail remains a fallback if the 1024 px preview cannot be loaded.
- A fresh grid1024 cache identity prevents old thumbnails and failed/obsolete 480-preview entries from being reused after updating.
- Full-screen preview now prefers get_screennail.cgi and falls back to the existing 1920 px resize request when needed.
- The compact 72×72 list continues to use the small thumbnail endpoint to minimize Wi-Fi traffic.
- Version: 1.3.11+20.
v1.3.10 — September 20, 2026
Accurate in-app changelog & sharper gallery thumbnails
- About now shows the actual recent release changes instead of the old generic feature list.
- The in-app changelog includes the Android RAW/ORF/DNG download fix and the persistent RAW only / JPG only / RAW + JPG filter with restoration of the last selected mode.
- The About changelog is localized in English, Russian and Ukrainian and is now synchronized with the repository and website changelogs.
- Sharper gallery tiles request a 480 px camera resize preview first; the small camera thumbnail remains a fallback.
- A fresh grid480 cache identity prevents older low-resolution cached thumbnails from being reused after updating.
- Gallery scaling uses high-quality Flutter filtering.
- Version: 1.3.10+19.
v1.3.9 — September 19, 2026
Persistent RAW / JPG / Both filter
- Three-state file type filter — choose RAW only, JPG only, or RAW + JPG.
- RAW mode includes ORF, DNG and RAW; JPG mode includes JPG and JPEG.
- The selected mode is saved and restored on the next app launch.
- Existing installs default to JPG only when no saved choice exists, matching previous behavior.
- Version: 1.3.9+18.
v1.3.8 — September 19, 2026
Android RAW download hotfix
- ORF/DNG/RAW downloads fixed on Android — RAW files now use MediaStore.Images and can be saved to DCIM/OlympusView like JPEG files.
- The fix applies to both foreground and background downloads.
- Successful RAW downloads now receive the normal persistent green downloaded marker.
- Users on v1.3.6 or newer can update normally through the built-in updater.
- Version: 1.3.8+17.
v1.3.7 — August 27, 2026
Camera-transfer reliability & stronger integration tests
- Fixed thumbnail fetch races — disk-cache lookup now finishes before a camera network slot is consumed.
- Bounded full-screen preview cache during rapid paging, even when swiping faster than neighbor preloading.
- Safer downloads — non-200 camera responses are rejected instead of being saved as files.
- Failed/truncated transfers never poison caches, verified with HTTP 500, garbage-body and mid-transfer failure scenarios.
- On-device integration tests now exercise a fake Olympus camera over real TCP sockets, filesystem cache persistence and thumbnail concurrency.
- Version: 1.3.7+16.
v1.3.6 — August 16, 2026
Updater reliability, downloaded-file cleanup & production signing
- One-time reinstall required for v1.3.5 and older — v1.3.6 switches from the temporary legacy debug signing certificate to the permanent production certificate. Uninstall the old Olympus View and install v1.3.6 once; future GitHub updates will work normally.
- Local settings and green-marker history reset on that uninstall; photos already saved on the phone and files on the camera are not affected.
- Visible update progress with downloaded/total MB and percent, explicit waiting-for-internet status, retry/cancel controls and an in-app Install button.
- Camera auto-connect pauses while an app update is active, preventing camera Wi-Fi without internet from stalling the APK download.
- Select downloaded — a green selection-mode button selects every file carrying the persistent green downloaded marker so they can be deleted from the camera in one batch.
- Production signing — GitHub APK releases now require the permanent app-signing key; Google Play uses a separate upload key while Play App Signing receives the same production signing identity.
- Version: 1.3.6+15.
v1.3.5 — August 16, 2026
Updater end-to-end test release
- Public updater test release — installed GitHub build 1.3.4 can now detect, download and install a real newer version through the built-in updater
- Updater regression tests cover version comparison, exact APK asset selection, missing APK handling and release-note parsing
- Version: 1.3.5+14; application behavior is otherwise the same as 1.3.4
v1.3.4 — August 16, 2026
Android downloads, diagnostics & preview reliability
- Background downloads continue while the app is minimized or the screen is off, with progress and completion notifications
- Persistent downloaded markers remain visible across restarts and normal app updates
- GitHub APK auto-update checks and downloads new direct releases; the Google Play flavor disables external APK installation
- Runtime diagnostics show installed build/version, build metadata, device/network/storage and camera state without exposing saved Wi-Fi passwords
- Preview priority and paired preloading keep the visible image responsive while downloads/preloads share the camera connection safely
- Fixed stuck preview spinners, downloaded-preview reuse, persistent green markers and stale AOT release artifacts
- Release build: 1.3.4+13; Android CI passes analyze/tests, APK/AAB, metadata, Play-policy and 16 KB checks
v1.3.2 — August 15, 2026
Android / Google Play preparation
- Android APK and AAB builds are green in GitHub Actions with analyzer and tests
- 16 KB page-size support verified for arm64-v8a and x86_64 native libraries
- Modern Android storage — downloads use MediaStore and appear in DCIM/OlympusView
