How do I selectively store and access data across devices without re-downloading entire libraries?

How do I control where my data is stored?

For instance: I create a lot of new files or voice memos in the course of my work, often on my phone. I want to keep some of them, but not on my phone, bc that fills up quickly. So I would like to move them elsewhere, for example to the cloud or an external storage device via the cloud. Then I want to delete them from my phone, but keep them in those other locations. Support tells you to do that by turning of synch & then deleting those files from your phone. HOWEVER - that means I can never turn synch back on again to upload new files, doesn’t it? Or else all the previously uploaded stuff gets re-downloaded, clogging up my phone again.

Maybe I just don’t get it but I feel I have zero control over how and where to store my data. *I do NOT want to synch everything to all my devices all of the time, but I would like to be able to use all my apps on all of my devices all of the time ACCESSING ONLY THOSE FILES I CHOOSE at any given moment*.

In other words: I want to be able to build a library of my files in my Cloud and then selectively choose what to access from that library on a device of my choice at a time of my choice, without having to re-download my entire library.

Can someone please tell me how to achieve that?? Just toggling synch on and off seems an incredibly blunt tool. Surely I’m not the only person with this issue and SURELY Apple is better than that.

Any input would be greatly appreciated. Thank you.

I'm not sure what you mean by "entire Library."

It's possible that iCloud is not what you want. iCloud isn't designed to be an external storage device where you pick up some files and not others. iCloud is a synchronization service, not an offsite storage bin or a backup service. iCloud Drive's purpose is to make all files exactly the same on all connected devices.

That said, iCloud has an Optimize Storage option that, for some files, keeps only pointers to files on the device rather than the files themselves. Clicking on the pointer loads that file from iCloud.com and keeps it available locally while you use it. Optimize makes sure that big files don't fill up a device by its automatically choosing to keep only most recent files locally. In iCloud Drive on an iPhone, a long press on a file brings up this menu

which allows you to remove the file from the phone, though the pointer remains. This works on iPads, iPhones, and Macs. Each device can choose different files to keep downloaded or offloaded. The status of most files, to keep local or offload, is automatically decided by the OS based on file size and recent use.

So you could keep some files in folders for which all the files are kept offloaded. Frankly, I think keeping up with this would be a pain-- the automatic decisions seem to work.

It may help to see this:

iCloud Photos is a completely different system from iCloud Drive, as you see at iCloud.com. Pictures can be treated differently. Rather than offloading the Photos Library, Optimized iCloud Photos keeps the Original picture files at iCloud.com, but keeps screen-sized images local so they can be viewed. There's no such thing as "low resolution Excel files."

But I have zero control over how or when that happens.

Absolutely true. That is a feature of iCloud. It may not be a feature you want.

Of course, with Photos, you can force a download if you go into edit mode, or if you export, etc.

I don't know much about voice memos, but they can be exported to iCloud as individual files.

Thank you for this, and also for the link to your other article. Both do help. I do not mistake iCloud for a backup - hence the mention of my external storage in my original query. “Library” in that context only meant “my collection of stuff”.

However - the system you describe only works with some of my stuff. I do not see, for example, in my iCloud Drive the place where my photos are kept in the cloud (even though they do synch); in that case, the automatic removal from my phone does seem to work, however, as I notice that after a while I have to re-download pics I originally took on the phone if I want to do anything with them. But I have zero control over how or when that happens.

Ditto voice memos - not visible in my iCloud folder. So there is no option to just keep a pointer on my phone, no “remove download” button, and they take up a LOT of space. I can only bin them or sort them into folders; there is no indicator in the voice mail app to tell me whether or not these are kept downloaded to my phone. If I check my phone storage, voice memos take up a lot of space, indicating that they are, indeed, kept on my phone. The fact that I can see them on both my phone and my iPad indicates that obviously, they must be synched to iCloud, as I have chosen in my settings. But there is no option to selectively synch them as needed.

Also - snyching is all well and good, but if that was the only function of iCloud, it would be pointless, bc then it would be necessary for all linked devices to have the same storage, which for most people is not the case.

Do you - or does anyone - have a suggestion re: voice memos?

Thanks.
