Built an Android app for OneDrive duplicate detection (something I wish Microsoft offered natively)
After years of dealing with duplicate photos and videos in OneDrive, I built a solution and wanted to share it with the community. **The problem:** - Samsung Gallery sync creates duplicates in both "Camera Roll" and "Samsung Gallery" folders - WhatsApp media gets backed up twice (original + shared copy) - App resets/reinstalls trigger re-uploads with "(1)" suffixes - No native duplicate detection in OneDrive **What I built:** OneDrive MediaOps - an Android app that scans for duplicates directly in the cloud. No need to download files to a desktop first. Key features: - Cloud-based scanning (no downloads required) - Algorithm visually identical photos even with different filenames - Preview before deleting - Batch deletion **Why cloud-based matters:** With 50GB+ of photos, downloading everything to run a desktop duplicate finder wasn't practical. This scans media directly via the Graph API. Available on Google Play: https://play.google.com/store/apps/details?id=com.onedrive.mediaops&pcampaignid=web_share Would love feedback from the community - especially if you've been dealing with the Samsung/OneDrive sync duplicate issue.
Corrupted VT+ transaction files
We are a small accounting company using VT+ Transaction on a local drive synchronized with OneDrive for backup and file storage. A few days ago when we tried to open the application, we suddenly started receiving the following error messages: Run Time Error 0 and Run Time Error 440, and the program does not start. According to VT+ support the program files are corrupted and the data can only be restored up to the year 2022, as the more recent backups are also affected. Somehow the system is overriding our backups, which makes the latest ones unusable. Any advice what could cause that and how to resolve the issue. Thanks
Can OneDrive mobile sync a specific local folder on Android or iOS?
Hi, I would like to understand what is officially supported regarding folder synchronization in the OneDrive mobile app on Android and iOS. Specifically: - Is it possible to select a specific local folder on a mobile device and configure OneDrive mobile to automatically sync that folder? - Or does the OneDrive mobile app only support manual uploads and limited automatic features such as camera roll backup? I am looking for an official clarification on the supported behavior of OneDrive on mobile devices. Thank you.
Resolving erroneous network errors with personal vault
I appreciate there are many(!) general OneDrive vault issues floating around but I wondered does anyone have a solution to a very specific oddity which has rendered OneDrive useless to me - and hence is preventing me purchasing it for use with my small business. Multiple Windows 11 PCs (all up to date, clean etc etc) - OneDrive working correctly, access personal vault and authenticate, all good can see files and access them. One PC hard-line ethernet, the other via WiFi OneDrive website - all working correctly including vault. Samsung Galaxy S10FE Android phone (all up to date, patched, clean etc etc). OneDrive app (v7.32.1) is working fine except for the vault... after authentication (PIN or Biometric I've tried both), the vault appears empty. Upon refreshing, it throws a nonsense "not connected to wifi/mobile data" error. Things to note... all devices are signed into the same MS account, I've tried different WiFi, just mobile data vs WiFi, I've uninstalled, rolled back to factory, cleared cache, reset app, logged-out and logged-back in again. Nothing root'ed or custom on the 'phone, just plain android with Samsung setup. I've confirmed definitely connected - as evidenced by other files upload and download fine, speedtest app shows steady 500/70 on the wifi. Also tried the same version of the app on a cheapie Motorola android phone, exactly the same issue. Can anyone help here - anyone else seen this? I need to make a decision as to whether to subscribe for my SB but currently it's useless - the vault is primarily what we need. Thanks in advance.
Search function on Onedrive for iOS not working
I have noticed that the search function on Onedrive for IPhone has stopped working and wondered if anyone else has had the same problem. I contacted MS support directly from within the app and received a reply which acknowledges that it is a real problem that they are working on but who knows when it will be resolved.
iOS File Provider: Never getting file updates
In my iOS app, I am using UIDocumentPickerViewController to pick a file from a OnDrive file provider. I am using startAccessingSecurityScopedResource on the url I receive and register an NSFilePresenter for this url to get change notifications. When I read the contents of the file, I am using file coordination. Reading the initial content is working fine. When now however the file is changed on some other machine, I expect a change notification from the file presenter and I should be able to read the fresh data from the updated file. This is however not working. I am only getting fresh data, when I terminate my app and re-pick the file with the UIDocumentPickerViewController. Is this a fundamental limitation of the OneDrive file provider under iOS or is there some secret on how to get fresh data while the app is running?
Onedrive on iOS sends some docx files to open in Word
Hello everyone. I have the Onedrive iOS app v16.19.8 installed. Lately, I have been working on three documents, which are modified copies of a fourth document. After Autosaving them, I tried to preview them on the app on my iPhone 15, and where 100% of the time the app would preview the document in an uneditable inherent viewer, these documents, and subsequently some other files, are viewed using the DEFAULT system viewer or it opens in the Word app I have installed. I require your diligent assistance in resolving this issue in the most efficient way possible. I can also attach screenshots if necessary. Many thanks.Onedrive not uploading photos from my phone since early April 2025
Hello! I have a Samsung Galaxy S23 ultra and 2 Windows PC's. Since I purchased the Samsung phone I set Onedrive to upload photos through the "Camera upload" option NOT the "Gallery sync". If the phone is a Samsung, "Camera upload" button will be automatically hidden. But still, it still uploads photos if "Gallery sync" is switched off. Since I purchased the S23, "Gallery sync" I always kept it switched off. I don't want to use "Gallery sync" for 2 reasons : On my Windows PC I get duplicated photos, each photos are in : "\OneDrive\Pictures\Camera Roll" AND in "\OneDrive\Pictures\Galerie Samsung\DCIM\Camera" I don't like the path "\OneDrive\Pictures\Galerie Samsung\DCIM\Camera". When all my photos are in "\OneDrive\Pictures\", I think it's better organized. So even if "Gallery sync" was switched off and "Camera upload" is hidden, everything was working well since 2023 and my PC got all photos from my phone. Until the second of April 2025 when suddenly it stopped syncing. I think there was a OneDrive Android app update on the same day. How can I get my "Camera upload"? Also I think Microsoft should be users the choice between "Camera upload" and "Gallery sync", and both options should be visible. Thanks GZ
