I can copy/move files from internal storage to SD Card if I use the built-in file manager. However, if I use any 3rd party file manager, the operation will fail. It is as though the SD Card is read-only. I can copy from the SD Card to internal storage just fine.

I've tried ES File Explorer, File Manager Pro, Solid Explorer and they all failed. I've given grants to write to the root of SD-Card. Does anyone have any idea how to fix this?

I really don't get it. At first, nothing works. Then when I install Root Explorer and grant storage access to the root of the SD-card, it immediately works.
Then I tried MiXplorer and it also works. Now when I return to Solid Explorer and it is working now.

What's going on? Does Root Explorer unlock something which makes it "click"? I don't get it at all. I only hope it is reliable in the long run and not switching "on" and "off" randomly.

Root Explorer has been the ultimate for me. I bought the paid version when it first came out years ago. It always acomplishes whatever task I need it to do.

Not Working

Not working for me.. I am using Honor V10... recently, I installed the android 10 (EMUI 10) update via ota (over the air). I have tried Root Explorer, ES file manager pro, but no file manager is able to write to external card except default file manager (which is pre installed)

PS: My phone is not rooted.

Go to developer settings and enable the option allow apps to write to external card... Have fun :)

I still have the same problem...
I have a new P30 Pro and Nano SD card Just arrived.
I can write (and read) the card by external reader, connecting the phone via USB to a PC, etc. etc.

But when the card is on the phone I can only use Heawei file manager!!!

I have enable the option allow apps to write to external card.

I've just update on EMUI 10 build 10.0.0186

I can't beleive I tried a lot file manager and also some alternative app like quickpic and no one works good!!!! :confused::confused::confused::(:(:mad::mad:

Hi there.
I have the exact same problem.
None of those steps helped me :(
I tried installing every single Root Explorer there is in the Play Store, but none worked.

I really don't get it. At first, nothing works. Then when I install Root Explorer and grant storage access to the root of the SD-card, it immediately works.
Then I tried MiXplorer and it also works. Now when I return to Solid Explorer and it is working now.

What's going on? Does Root Explorer unlock something which makes it "click"? I don't get it at all. I only hope it is reliable in the long run and not switching "on" and "off" randomly.

Which one of the Root Explorer apps that we can find on Play Store did the trick for you ?

I enabled the default browser and the HiCare app (actually they were not disabled, so I just opened them to complete their setup) but this did not help either.

I even formatted the memory card (using my phone "format card" option) and then reset my phone to factory defaults and set it up again from the beginning without restoring backups.
I still have not found a solution to thus issue, though.

Any ideas anyone?

I had to instal FX file commander to get SD card write permission....I can't make it stick, every time I reboot I have to reset the sd card write permission.

I have similar problems relating to this thread on my mate 20 pro after updating to Android 10 (EMUI 10). I've tried all the methods mentioned here and it worked briefly before restarting the phone. After restarting the phone, it went back to being unable to copy files to External Storage.
I noticed that i was able to delete and rename files on the external storage but i just can't seem to copy anything into it.
I can copy files from the external card to internal storage but not the other way around.
Tried using MiXplorer, the only way i can copy files into the external card is by this method:
i copied the file and it shows error, but there's an image of the file created on the external card with 0 kb. Then i overwrite the file and replacing the '0 kb' file and it worked. And another method to just to use the built-in file manager which is a pain to use and the UI are crappy.
It was a lengthy method and therefore I decided to downgrade to Android 9 for now.
I also noticed i can't change the download directory of my Ttorrent app to any folder of my choice in external storage.

anyone can suggest a better method to overwrite this external drive issue? Thanks in advanced.

This this the "official" reply at the Huawei forums:

https://consumer.huawei.com/en/comm...-disabled-for-3rd-party-apps-!/topicId_90489/

Now, what I've come to notice is the following:

- All Huawei and Google apps I have tried, do have access to the memory card (e.g. Google Maps is allowed to save its offline maps on the SD card, the same for Google News and the articles it downloads)
- Some 3rd party apps do have access. E.g. Here We Go maps can save its maps on the external card. ASR Voice Recorder can save its recordings to a specific memory card folder, the one that is automatically created -on the card- by the app when it is installed on the phone. Maybe there are other app that we will find they can, too.
- So it seems that the rule is not general, as Huawei implies at that thread I have posted above.

My biggest concern was that MixPlorer has now limited use, and this is kind of sad as it was my favorite explorer.
Huawei Files manager is not bad, it's actually quite OK, but it bothers me that you cannot add 3rd party clouds on it. If it had that option I would be happy with it. I like it that it has that "favorites" option. For now I have created a folder "My Archives" on the internal memory and I initially save almost everything there (e.g. my Nova Launcher backups). Then I use Huawei Files manager to move them to the external memory card on the folders I want.

Hey that's a good idea of creating a temp folder on your internal drive before using Huawei file manager to transfer everything out to your external card. However it requires additional steps to get it done but it's a good idea nonetheless. Thanks for that suggestion. For me i'm so used to be using solid explorer to do all my file operations as it has google drive integration which makes it easy n fast to transfer between drives. So i guess my best bet is to downgrade to android 9, it's just much more comfortable to work with and in my opinion, android 10 is not that big of a deal and not much substantial changes anyway. Hehe.

Every reboot I always have this facing problem!
Sometime I must reboot because my smartphone switch off for low battery....

When I reboot try to disable and re-enable the special option in developer menù, also try to uninstall and after install again the memory card (from setup/memory menù).
After that try to copy some file to memory card with default file manager an default Gallery...
Sometimes it is enough sometimes I have to try more and more... But after several time it works!

    Mixplorer works great. Root Explorer also works.
    Thank you for your recommendation!
