P: When specifying a storage location on a different drive the application still uses the C:

Hi I have lightroom 5 desktop there appears no way to stop lightroom catologue data saving to the c drive instead of external drive.I use use external drive to connect to a laptop as well. The original will photos will be saved on external drive.

any alternatives available

Thanks

In Lightroom CC, why can I choose the folder for the originals freely but not the cache location?

Same problem using Lightroom. No way to change the default storage location. It always is putting scratch files on C: even though the images are stored on my other drive. C: is full after 5-10 minutes of editing.

I just bought lightroom CC and this is like some sort of sick joke.

I, too, have a 256 G boot drive WHICH IS ONLY FOR SYSTEM AND APPS as is the default setup for most competently-built PCs.  I don't really want to blow 30G of storage on my C drive for chrissake, not to mention the forced obligation to keep "smart previews" there as well. 

That CC is forging me to keep all y my smart previews and everything else on my C drive is head-shakingly idiotic.  Don't any of the Adobe designers work on a Windows box with more than one drive?  This is like a one-line setting somewhere, there's nothing advanced about being able to change a default folder.

I am adamant about this problem as well. I have 250 users with 256GB SSD C: drives which are loaded with architectural applications, and 500GB D drives which are intended for private data just like this. (Note: we programmatically move the Desktop, Documents, and Downloads to the D as well)

The C: drive is just not a good place for the ...previews and ...proxies folders.

I purchased a new SSD just for the catalog data, but I can't use it because it forces use of the "C" drive.  I can easily change where the library is stored, but the required use of the C drive for a lot of data means I can't use Lightroom CC.

Same problem:

C:\Users\user\AppData\Local\Adobe\Lightroom CC\Data

Is growing too large for its location, need to move it..
Especially the proxys folder.

Yeah, well, to the earlier point, my unmovable folder chews up around 20GB - it'd be nice to be able to put that somewhere user-specified.  It's a comment and an ask, not an indictment. 🙂

You cannot move that local library from the default location. You CAN have any locally stored originals on a different drive (but not a NAS), and there are tools available in the LRCC Preferences>Local Storage tab to help you manage the impact of that local library on the default disk drive. There's a certain amount of "required space" which varies depending on the number of synced images, but beyond that you can control how much additional space is used.
