How to change or move local storage to a different drive?

I have a dedicated SSD (D:) that I used to use for my LR Classic catalog and full size previews.

Since moving to LR CC, it insists on using my C: drive, leaving my SSD 😧 drive unused, and it runs my my C: drive low on space.

 

How do I change the drive that is used for local storage from C: to D:?

Correct answer Jim Wilde

You can change the location of the locally stored copy of originals via the Preferences>Local Storage tab.

However, you can't change the location of the local library that LRCC requires for its catalog and previews cache, that's fixed to the user's library (in AppData/Local on Windows, in Pictures on MacOS). The best you can do is set the photo cache size to the lowest % figure, but you can't eliminate the space usage completely.

Hey there, 
Just had the same problem trying to upload new pictures to Lightroom.
You can change it pretty easyily now. Just go to the tab "Edit" --> Then click on to the Default settings button on the bottom. Then a Window opens up an there you can change the location of where it safes the pictures.

Seems to work perfectly. I just reassigned my data (originals) to a larger external 😧 drive (4TB). The other matter remains on my C: drive. This has allowed me to save precious space on my small internal SSD (512GB).

As mentioned on here by others, LR CC doesn't allow you via settings to change where the "previews" folder is (aren't able to set it to a non C drive). I did find a workaround by setting up a symlink (called a directory junction by windows). A symlink (short for symbolic link) is like a shortcut for files and folders. Basically you create a "previews" folder on a different drive, delete your "previews" folder on your C:\ drive then you you create the symlink via the windows command prompt (have to run in administative mode).

 

Detailed Instructions:

1) Delete your current "previews" folder. Should be located in similar type path:

C:\Users\John Doe\AppData\Local\Adobe\Lightroom CC\Data\e96316ca204f4c848aac8ac9a0f7955a\previews

2) Create a new "previews" folder in your non C: drive. Here's where I created mine:

E:\Program Files\Adobe Lightroom CC\previews

3) Open a command prompt in admin mode. In windows 10, the easest way is to search for CMD in the search bar, right click and run as Administrator

4) Run this command (updating the pathnames to match where your "previews" folders were/are stored:

mklink /J "C:\Users\John Doe\AppData\Local\Adobe\Lightroom CC\Data\e96316ca204f4c848aac8ac9a0f7955a\previews" "E:\Program Files\Adobe Lightroom CC\previews"

You should see a "Junction created" message in the command window. You should also see in your app data folder on your C: a "previews" folder show up with a small arrow to show it's a junction. Now Lightroom will rebuild your previews and store them on the othe r drive.

You can reduce the size of "Lightroom Catalog Previews" which normally takes a lot space on your local drive. Change the location of your Camera Raw Cache to your external drive (go to Preferences > Performance > Camera Raw Cache Settings). Then build standard previews for all your photos (Library > Previews > Build Standard-Sized Previews).

This thread is about the cloud-centric Lightroom app, your instructions are for the Lightroom Classic app which works in a different way.

As stated, there is no way to do this in the Lightroom settings. However, it is possible to set up symbolic link to redirect Lightroom's directory to another location. I found the solution here:

https://techgenix.com/folder-redirections-in-windows/

 

I recommend reading this page before trying this so you understand how it works!

 

Here's what I did.

1. I created a new folder on my 😧 drive:  D:\Lightroom\Appdata\Local

2. I navigated to Lightroom's directory, which on Windows is:

C:\Users\(username)\AppData\Local\Adobe\Lightroom CC\Data

3. I copied the contents of the Lightroom directory to my new folder on the 😧 drive

4. I renamed the Lightroom directory from ...\Data to ...\Data.Save

5. I opened an "elevated" (run as admin) command prompt and entered this command:

mklink /J "C:\Users\greyn\AppData\Local\Adobe\Lightroom CC\Data" "D:\Lightroom\Appdata\Local"

 

Now Lightroom thinks I have a very large C: drive.

 

The MacOS equivalent of mklink is ln, but I don't know how it's used. Maybe a Mac user can add the procedured here.

I know this is an old question, but I will answer it for posterity. 

 

While you cannot turn off cloud storage, it is helpful to remember that you can export photos to a local folder once you have edited them then delete the photo from Lightroom itself. 

 

If you want to process a batch of RAW photos into JPGs and never see them again, you can do a batch edit, send them to a local drive, then delete the Lightroom copies. Deleting the photo from Lightroom will not affect a file that you exported.

Really?
"once you have edited them then delete the photo from Lightroom itself. "
The idea of LR is to have everyphoto in place. Including labels, starts, folders. With the ability to share pics with others etc. Removing them photos from LR makes this software almost useless.

Any news on it? Is there any chance that this problem will be solved? LR is absolutely killing my C drive and I have multiple additional drives half empty.

So this is possible (at least in macOS). Lightroom CC stores the cached images inside the Users folder (i.e. Users\Adam\Pictures) so if you move the location of your user folder, Lightroom will use that new location. I did that this morning. My situation is I got a new Mac Pro, added an 8TB M.2 RAID which can read/write >7GB/s so wanted to use that instead of the SSD macOS was installed on. It's rather straightforward - here's a detailed way to do that.

I recognize that this means everything moves over to this drive which in my case, was what I wanted. I have a rather large Apple Photos library as well and glad to have it running on the faster drive.

One caveat is that I just moved it this morning and actually came here because when I go into Lightroom, it tells me it's in the process of moving my photos (assume it means the cache) and it's taking forever: (Disk2 is my M.2 RAID)

There is NO "Local Storage" tab in my current version of Lightroom Classic.

This is a bogus answer!
This answer solved absolutely nothing.

- And there is no attempt to at least give an explanation to why the problem has no solution!

It makes no senseto mark the issue as SOLVED!
There is no solution, there is no explanation

 - The issue is far from SOLVED!
It's an open wound and it's still bleeding

- Just because the doc rushed by, claped his pockets and stated that he was out off bandages, realy didn't heal the patient!

Bogus? Really? Some of the definitions of "bogus" are "fake, fraudulent, deceptive, spurious, false, sham", and I'm struggling to see how any of those apply to the answer that I gave. Read the original post again...the question asked was "how can I change the drive that is used for local storage?", and my answer basically was "you can't, apart from the local copy of the original images". Nothing "fake, fraudulent, deceptive, etc, etc." about that, all completely accurate.

 

Granted, that's not the answer you wanted to hear, but I don't see how that justifies your attack on my integrity. I'm just a user the same as you, trying to answer other's user's questions to the best of my ability....I don't work for Adobe, so if you thought you were talking to an Adobe representative then you are sadly mistaken (though even I were an Adobe employee that still doesn't justify attacks like that).

 

Ultimately, if you just want to vent at Adobe, you're doing it in the wrong forum....this is just a User-to-User forum which Adobe provides for the Adobe community to help each other. The better place to get your message to Adobe is via their offical feedback site (https://feedback.photoshop.com/topics/lightroom-desktop-cloudbased/5f5f2093785c1f1e6cc40874), where you will find there's already an existing thread asking for more user flexibility regarding the local storage requirements. Look it up and add your vote, and any supportive comments you would like to make (though might I suggest using a more constructive tone?).

 

You might also take the opportunity to ask Adobe for the explanatiion that you're looking for about why the current system has been so designed. I think I know, but because I'm not certain I'll refrain from speculative posts.
