Help Having different partitions in Android?

[johnyb12]

Hello. I use an Android 3 device. It has a pdf app. That device see the sd card as ext_sd as in the following picture.

Chemistry and Physics the folders I created on my windows pc in the sd card. I wish to have different partitions that is more than one "ext_sd". Is this possible? I must do it on windows pc.

Thanks and regards,

You can partition the removable SD card on a PC if you want, but there's a problem: when you boot the tablet it will only mount the first partition it finds on the card! The operating system doesn't expect the card to be partitioned, and will make no attempt to look for other partitions and mount those. Hence the net effect of partitioning the card will be to reduce its useful capacity.

(As an aside: there are apps that use a second partition on the card for special purposes, but you need to root the device in order to use them. Otherwise what I say above is correct).

But why do you want to partition the card anyway? You can create as many folders or sub-folders as you like, but what would you gain from partitioning it?

Having two different "ext_sd" there can make the organization better since I put different things into different partitions.

But aren't there always ways to bewilder the operating system as if two different sd card is mounted, each card being the partitions?

Isn't that what folders are for? You can put folders inside folders inside folders and organise to your heart's delight, there's no need to partition for this purpose. That just adds unnecessary complexity and is less flexible: if you fill one partiton but have space in the other you need to start putting files in the "wrong" partition, a problem that doesn't arise if you just use different folder trees in the same partition.

You need root access in order to add the necessary scripts to the system. You can't do this on an unrooted device.

You are right! "Folders inside folders" works exactly in the way what I want. I didn't thought that. But I still wonder if having such partitions in Android both possible and easy? Do experienced users prefer such a thing?

Thank you very much for your advices.

Any file explorer on Android is capable of creating any number of folders within folders. I do this type of thing on a daily basis. I use Solid explorer from the play store

It's not possible to set up within the phone, and as I say won't work without root and some extra software - and not all devices can even be rooted in the first place. Even then the software that's designed to use additional partitions is designed to use just one extra partition for specific purposes, so if you wanted multiple partitions you'd end up having to edit the startup scripts (which live in areas you need root to even see) yourself.

So most people would not call it "easy" . And to be honest I've never heard of anyone doing it except for the specific purpose I alluded to above (using a partition formatted with an Linux file system, as opposed to the usual fat32, as additional app space).
