I have never had a corrupted file with FileBrowser Pro whereas I ran into it with the built-in Files app. I use it with two different Samsung SSDs.
And…?

A lot of people around the World has never experienced Covid, but even if you haven’t either, will that help those, who do? The people left behind the millions, that have ended up in graves?

OK, formulated a bit harsh, but still. Will do as a.n analogy ;-)

Will it help anybody, who has lost data using the Files App, that you have not lost data (or discovered the loss, yet ;-)

I have used both Files App and the FE File Explorer Pro App for years. The File Explorer Pro for both iOS (now 14.8) and Android (now 11). The latter even allows a kind of Air Drop like operation between iOS and Android - far more reliable, than anything involving the Apple Files App for transfers/copy to ”anywhere”. Especially if large amounts of data is involved, like the 20-50GB or more of video and stills coming from your “big camera” each day during travel.

The File App has never been reliable (from iPhone, iPad or iPad Pro over my home WiFi 6 to anywhere - including local NAS - or to external drives (powered or via a powered USB Hub). File Explorer Pro is far more reliable (NOT 100%, I have experienced “oddities”, but not on a regular basis).

The biggest problem is, that there is no way to verify, that a transfer went, as it should. This means, that you have no practical way to check, if your data is safe, if your transfer includes large amounts of large files, when only iOS or ipadOS is involved during travel.

If backups of photos, videos and audio recordings from a trip of a lifetime is involved, I would never, ever rely on iOS/ipadOS based gear, when alternatives are available at far lower costs. All my iPads (Pro or not) are now only used for browsing, and some editing via Affinity Apps (I subscribe to Adobes tools, but they are only usable on PC and Mac for my use).

I’m not forking serious money out for a crippled MacBook Air called iPad Pro M1 ;-)

I do not use iCloud, OneDrive or Google One for any serious target store (this moment, iCloud stores 4.5 megabyte, and I have no longer any subscription to storage); they do NOT guarantee anything worth while for non-commercial accounts, and if they experience an “oops moment”, tough luck on you. Maybe they apologize, but your data may still be gone forever.

I own an old Microsoft Surface Pro 4 (late 2015), and for travel it is far, far better (and there is lots of software, also verifying backups to anywhere). Speed wise it still runs rings (at 5 Gigabit USB-A) around any iPad Pro when USB-C (up to 10 gigabit) is involved. I have never, ever experienced a simple data loss on my old (or new) Windows or Mac(book) machinery. Very few times, once a year maybe, the verify process discovers an error in the tens and tens of terabytes transferred here, there and everywhere each year. With Files App it nearly happens on a daily basis while traveling, that something untoward happens. Missing files. Missing connections to shares. Missing drives. Damaged drive content etc.

Same gear does not exhibit that behavior, when used on my Samsung smartphone or any of my Windows or Mac machines. That - at least - tells me something ;-)

Using iPhones is out. They’re horribly slow. My late 2020 iPhone 12 Pro 256 GByte has trouble copying data to an external SSD (powered) at 1/10 the speed, that I get when using my late 2019 Samsung Galaxy Note 10 Plus 512GB (250-275 megabyte per second) that also easily outperforms my iPads (pro or not).

Your mileage may vary, but is your data really safe?

Regards

I agree, Files app is unreliable. As I said, I have experienced data loss with the Files app but never once with FileBrowser and I have done a lot of transfers across SSDs, HDDs, flash drives and over SMB connections. I have confidence that my data is safe but I am careful - I copy and verify and then delete if desired; I don't use Move. As to the cloud, I don't generally use cloud services as I travel to a lot of places with spotty or no Internet connectivity.

Just re-ran my Files copy test on iPadOS 15, copying 165 Canon RAW images (approx. 2GB) from my 2021 12.9 iPad Pro to an attached Samsung 500GB SSD formatted as exFAT. All images copied over cleanly - first time there has not been file corruption when running this test with Files.

Is the issue only with exFat? My M1 MacBook has been sent for display repair (dots) and I will be using my iPad Pro as the main device. The external drive is formatted in APFS and contains my main backup.

I remember last year I had to reformat some cards after connecting them to iPad Pro.

I gave up copying images/videos from my iPad Pro… too many times they never copy successfully. However, I never have a problem with copying images/videos to the iPad Pro.

Yeah, I still FileBrowser Pro. Just wanted to test a new version here.

I can still get the message to repair the storage when I connect it back to Windows but every time the repair said nothing had to be fixed. Irritating.

I formatted the SanDisk Ultra Dual Drive Luxe 512GB flash drive to NTFS (read-only on iOS) and so far, so good. No corruption yet and no messages about needing repair after swapping the stick among iPad (iOS 14), Windows 7 and Windows 10.

I think I'll probably grab the 1TB version for $115. My use-case is primarily write on Windows, read on iPad (watching personal rips via Infuse Pro). This would give me a nice selection of videos in my pocket that I can watch on any of my USB-C iPads without any wires dangling. It's probably gonna take forever to write 1TB but usage will be write once, read many so at least the pain is just one time.

I had an issue with video files being corrupted /disappearing from a Sandisk extreme simply by plugging it in to my iPad Pro 4th gen to transfer files from my laptop… I never could figure why it was happening but gave up and just created a iCloud folder on my laptop, I now just save my work to iCloud and open the files I need on the iPad that way….works pretty well… I do lots of astronomy work so it was kind of a big deal when those files went missing https://share.icloud.com/photos/0EgqUP2D5SAocj6H0gX9GGMqg

Yeah, I always make sure I have separate backups before I plug a storage device into any of my iPads - I just haven't come to trust it. Nice photos, by the way. What are you shooting with?

For movies, I've recently been using a small USB-C uSD card reader -

https://www.amazon.com/gp/product/B08131PLHZ

with a 400GB card. I think I'll do the same and reformat it as NTFS. Kind of a pain as the card is full and takes time to rewrite but I think it's worth the time.

I remember checking before and the 512GB microSD cards were more expensive than the SanDisk Dual Drive. My only other device that uses uSD are the Raspberry Pis so there isn't an incentive to get uSD. Plus, I have several old PCs that don't have USB-C ports and I really like how the SanDisk is 2-in-1.

Wish Samsung would make something similar. Their dual USB-A/C flash drive is bulkier and uses adapters.

Yeah, they are but I had the 400GB card from a different use and the reader was only $12 and I have a couple of USB-C to USB-A adapters for my older machines. The smaller devices are a lot handier than my SSDs for this kind of application.

So much footage I lost shooting in Norway, I'm still regretting it. They can update Files, iPadOS, make it more reliable. But I don't think I'll trust it enough to let it hande my videos from camera ever again.

Copying a lot of large files from microSD reader to external SSD (via hub). This summer so iPadOS 14. Media files are there, take space but are unreadable. Lesson learned, leave that kind of work to tested and tried (real) computers.

Real computer? Smh. But I’ve experienced media files corruption when moving files to/from the iPad, but that’s mostly from dealing with the Files app. But ever since i switched over to FilesBrowser Pro… haven’t had any issues. I use the Files app to move files within iPadOS (very useful), but never around any external drive.

A couple of things (I'm the OP) - it appears fixed in 15 and in 14, I quit using Files and switched to FileBrowser Pro and never saw the problem there.

Too late for any of that. Everyone’s praising FileBrowser, I say it’s pathetic you have/had to rely on 3rd party app to make sure something as basic as copying won’t corrupt your files.

hi, im new user planning to use an iPad as my main computing device while traveling, i wonder if this issue is fixed on iPadOS 15 ? if it is not, can i use 3rd party files manager apps called Documents (developed by Readdle Technologies Limited) ? thanks

Glad that I found this thread as I was assuming that my SD card was broken. I was using my iPad Pro 2021 to transfer photos from an SD card directly to an external SSD via a USB C hub. A lot of files were corrupted. But not only those on the destination drive, even the source files on the camera SD are damaged. As many of you mentioned, it’s hard to trust an iPad now for such a simple task. Is there a way to recover the corrupted files?

I think the main issue is not being able to eject the drives properly before disconnecting them physically.

Well, ends up me buying some new SDs just to be on the safe side as well as a MB Air M1 for backup on the go…
