It’s been a year since I set up an offline visualization solution for vector and raster data over a very large area (1/2 France).
For vectors, it’s possible on the tablet (500 mo).
But for rasters how can I do I have 80go orthophoto and 15go scan.
The opening was super fluid and corresponded to my needs and I did the update and everything is broken.
I understand the need to link to file access but for rasters it’s only read right ?
Do you have a solution to communicate to me knowing that my tablet fleet is already purchased in 64gb of memory so I cannot transfer my rasters to the internal memory ?

Crapaud04 , my understanding of your issue is that your device’s internal memory where the primary /Android/data/ch.opengis.qfield/files resides doesn’t have enough space, is that a proper understanding of your issue?
Imported from GitHub comment by @nirvn on 2022-05-10T10:17:04Z
Yes, and I think I’m not the only one using Qfield for this need.
And the weight of the rasters only increasing will be a recurring problem.

When you open QField and tap on the open local file button, you should see an “Additional files directory” folder:
This opens to your external sd card’s Android/data/ch.opengis.qfield/ directory. You can copy projects and datasets there and open it in QField.
Are you seeing this folder, and have you tried opening datasets from there?
Imported from GitHub comment by @nirvn on 2022-05-10T12:23:15Z
I might also be misunderstanding you here. Are you referring the datasets that you but in the QField/basemaps folder whereas those are accessible to all projects (ie localized paths)?
Imported from GitHub comment by @nirvn on 2022-05-10T13:00:38Z
Yes is basemaps of all projects.
I tested and i don’t acces to this directory in App explorer and winbows explorer same view.
But i click to Additionnal files directory and i see way to the directory in sd card.
For information :
My tablet is Samsung Galaxy Tab Active Pro in Android 11.

Crapaud04 , ok, I’m sure we can find a solution here.
One thing can be done. You could move the storage from internal to SD card in the app properties, ie:
You find that by long pressing on the QField icon in your launcher and clicking on the (i) button or via settings → applications → QField.
As for not seeing any folders in the Android/data directory on windows, have you tried showing hidden files there (I’m not on a windows machine so it’s a long shot in the dark 
).

nirvn I have tested this solution in first before my message.
And i see this directory in internal storage. After change storage location i have don’t new directory in my sdcard.
In internal storage, i have the full directory and imported data set my files is in internal storage.

Crapaud04 , does windows explorer allow you to create a folder in your card’s Android/data folder? If so can you try to create a “ch.opengis.qfield” folder, then a “files” child folder?
Imported from GitHub comment by @nirvn on 2022-05-10T15:03:09Z
nirvn Is not possible in windows and explorer app Android. “access denied”
After short search on the net this problem is Google and Android 11 ans after.

Crapaud04 , odd, by most accounts out there you should be able to access content. Is the USB connection set to file transfer (not MTP)? And his your SD card encrypted?

I tested to connect on hub usb my sdcard. I see this folder sdcard/Android/data/ch.opengis.qfield/files but this folder is empty.
So i change storage location yesterday.
I tested to copy my files in this folder is okey. And open this files on qfield is okey.
But my project don’t see this files …

Crapaud04 , sounds like progress I’ll get back to you later today with a test build.
Imported from GitHub comment by @nirvn on 2022-05-11T09:32:25Z
nirvn okey 
Imported from GitHub comment by @Crapaud04 on 2022-05-11T09:49:17Z
The only problem that strikes me is that the action of change storage does nothing since on the SD card there is nothing.
Imported from GitHub comment by @Crapaud04 on 2022-05-11T09:54:42Z
Crapaud04 , as far as I can make it, moving the storage to the external drive only moves the app itself, not the files data content.

Crapaud04 , please test the APKs here Handle _all_ external dirs as potential QField data dirs by nirvn · Pull Request #2886 · opengisch/QField · GitHub
Upon installation, run the app (QField Beta) once for it to create the directories in your SD card’s Android/data/… location. Note that the relevant app directory here will be ch.opengis.qfield_beta on your SD card.
Your basemaps should register just fine 
Imported from GitHub comment by @nirvn on 2022-05-11T11:14:05Z
nirvn I finich all test on Beta version 2886 .
I still do not see in the android file explorer nor that of windows the interior of the Sdcard / Android / data folders
So I have to take out my SD card and plug it live on the computer to see these files.
I moved my 2 large files there to the basemaps folder.
I changed in my QGIS mobile project the location folder of the basemaps with notepad++.
example: old path: /storage/9C33-6BBD/qgis/Ortho_50_zs.gpkg
New path: /storage/9C33-6BBD/Android/data/ch.opengis.qfield_beta/files/QField/basemaps/Ortho_50_zs.gpkg
Unless it can do Jeux de données locaux partagés - Documentation de l'écosystème QField?
If so do you have more screenshots because I couldn’t do it.

Crapaud04 , did you succeed when renaming paths? What is the path where you store your qgs project ?
As you’re pointing out there would be better ways to achieve what you want.
Imported from GitHub comment by @nirvn on 2022-05-11T15:58:57Z
For the record, if your ortho dataset is stored in an absolute path, that means it isn’t handled as a “basemap” dataset within a localized path (in our case here your sd card/Android/data/…/files/QField/basemaps)
The path for such basemap would be something like localized:ortho.gpkg
