Lightroom Desktop: Available space issue

Hi!
 
I'm using Lightroom CC and when I go into Preferences > Local Storage I get this:



It is set to use 25% of remaining disk space. Also, it show that available space is "98.33GB" if I understand this correctly.

However, the available disk space on my drive is 7.37GB. So I would like Lightroom to reduce the Photo cache.

Why does Lightroom think that I have almost 100GB available when I only have a bit over 7GB?

From this screenshot I can't see what the available space on your HD really is, but Lightroom does seem to think it's about 98 GB. So why don't you simply lower the 25% setting to fee up space?

No... I shouldn’t have to lower the space to 1% or something to make up for a bug :)

It might not be a bug. MacOS X has processes that can sometimes take up temporary space (for example Time Machine makes a local backup when your Time Machine disk is not available, but will give up that space when needed for something else), so perhaps Lightroom is including that in its calculation.

And if you want to free up space now, the only way of doing that is taking action yourself. If it is a bug it needs to be corrected, but it the meantime you may want to help yourself by lowering that percentage...

You are talking about "Purgeable disk space" in macOS. I have 117.9MB of Purgeable disk space, so it is not that.

Perhaps you need to empty your trash?

It is empty. And it wouldn’t make any difference. Thanks for the suggestion.

Where did you check to find out that your available disk space is 7.37GB?

In Finder. I also checked Disk Utility.

I cleaned up some stuff on my disk and now I have 13GB available on my disk. Lightroom thinks I have 104GB. Makes no sense at all...

I checked my version of Lightroom CC and it shows quite a bit LESS free space than the Finder does, not much more. It does indeed not make sense, but my advice stands. If Lightroom thinks there is 100 GB of free space on your disk, and you let it use 25% of that in the preferences, then most likely it is using 25 to 30 GB of disk space to cache images locally. So if you really want to clear up disk space, then change this setting to as low as it gets.

You can say “I shouldn't have to do that” and you're right, but do you want a solution to your problem or not?

In fact, looking at your screenshot confirms this: Lightroom uses 25.86 GB as cache (up from 24.44 GB in your first screenshot)...

Yes I can lower the photo cache. That won’t solve the problem though :) My problem is not that my disk is full, my problem is that Lightroom CC calculates the free space wrongly and thus caches too much locally.

When I get in dire need of disk space, I will indeed lower the photo cache, (thank you for the tip) but hopefully Adobe will fix this bug before that.

Can I contact Adobe with bug reports somehow? I did write in their customer forums but got no replies other than a tip to write here (since this forum seems to be monitored better). I have tried to contact Adobe using the chat but it just tells me to wait and then says “Thank you, bye!” and nothing more...

You've already contacted Adobe. This is the forum to report bugs and request features.

BTW, I would lower that cache right now if I were you. Having only about 10 GB free space is very limited and could be a problem already. Your entire computer may run slower than it has to because there is too little space for temporary storage.

Oh ok. Let’s hope someone from Adobe sees this and takes the appropriate measures to rectify this.

Thank you for your help I really appreciate it!

Hi Linus,

Thanks for your post.

So, as Johan mentioned, you have, indeed, contacted Adobe. I'm one of those guys! We are discussing this issue and will log a bug if it's not already been done.

An update here and some more issues.

Rick has contacted me and they seem to be working on a solution to this. I hope they can find a fix soon :)


On another note... I tried to lower the "Photo Cache" size to 10% instead, so now my settings look like this:



Shouldn't this make the "Originals" folder smaller now? Because nothing happens and I still have 95GB of photos on my drive (yes, I have restarted Lightroom CC after making the change).

Am I misunderstanding this feature?

Yes, it should make it smaller (the 9.92 GB in the preferences), but this may be part of the problem.

It seems to be doing something actually. Now the Lightroom "originals" folder is only 87GB. So in a few weeks it may be at the correct cache size :D

There is supposed to be some intelligence built-in to the space management process. Although I don't have any specifics on what checks are done, I can easily imagine for example that deleting the imported files from the local system, as soon at they have been synced and backed up, might be delayed for a while depending on actual free space on the drive and frequency of access. I've just checked and, although I do not have the "Store a copy locally" enabled, some imports I did back in early February are still in the local cache.....and furthermore, LRCC knows it. So if I access those files frequently (which I would more likely do in the month or two after import) I would expect LRCC to use the local copy in preference to downloading the original from the cloud whenever I open the file in Detail view. But as my use of those files becomes less and less frequent, they'd more likely become eligible for deletion.

I have no problem with that behaviour provided it does take actual free space availability into consideration. I have plenty of free space on the drive in question, so can't really test that.

Hello, is there an update on this? This was 2 years ago but I have the exact same problem as the author of this thread. How to make Lightroom reduce the local storage which is taken? My disk is full but Lightroom thinks I have 129GB free. Thanks!

Hello, this was 2 years ago but I have exactly the same problem as the author. My disk is almost full, and Lightroom keeps 100GB of local copies and thinks I have 129GB of free space.

I have a 256GB drive and I set lightroom to use up to 25% of the free space. So independent of how much space lightroom thinks is free, it should not be using up 100GB for local copies. 

Thanks much a lot for any help on this!

I also have the same problem. Lightroom says I have 104 GB available space and that it's using 10.29 GB for Photo Cache, but the reality is that I have 2.62 GB free and it's using 89.1GB for originals storage..
Is it safe to delete the content of this originals folder after it's done syncing?

I too have the same issue on Windows with Lightroom CC. My disk has 15GB free but Lightroom thinks that 81.87GB is free. Moreover, the Photo Cache is listed as 20.34GB whereas the actual directory size on the disk is 64.1GB! It would be good to get a reply from Adobe since this bug has been reported for 2 years. Thanks.

So... I'm wondering why Adobe hasn't acknowledged this bug yet? I just found out about it because my MacBook Pro was running low on disk space. Lightroom CC (Cloud version) is reporting that I have roughly 100GB free space. macOS is reporting that I have roughly 5-10GB of free space and I just tried to import 20GB of RAW images, which obviously won't fit, because Lightroom has to import all the RAW files first.

I ended up deleting the WHOLE library making sure everything is backed up and now Lightroom is showing me the correct amount of free space compared to macOS.

This IS a bug in Lightroom and not on the users end as some of you suggests.

Adobe please fix this issue, it's getting stupid with having to fix all your bugs by deleting the local version of your library.

I will join and report that I have the same issue.  Lightroom cc believes I have 106.51 GB of available space, but the desk utility from my Mac shows only 5.06 GB -- I assume most is taken up by 
Lightroom because I set the local storage to be 10% (1TB x 10% = ~100 MB).  Please fix the issue and return my storage space!

I'd just cross-reference a similar thread on this forum.  According to that thread, the issue arises from Time Machine storing temporary copies in the boot drive.  For some reason Lightroom recognizes spaces taken by TM backups as "unavailable space."  But those TM backups actually are available (to OSX at least) if space is needed. 

In that case, it's clear there's a bug on Lightroom's part.

Isn’t that the exact opposite issue?

I wonder if Lightroom thinks of its own cache space as free space.  I migrated and uploaded 219Gb of photos to Creative Cloud using LRCC.  Then I selected the "Store a copy of all originals at the specified location".  LRCC downloaded the originals to the folder I specified and it took up about that same amount of space. Windows said I had about 69Gb free and that's about what LRCC said.  Now I would like to NOT store originals locally and leave them in Creative Cloud.  I copied the local orignals folder to an external drive just in case.  I UNchecked the Store originals locally option, the Store smart previews option is UNchecked and I have 0% cache size set.  I restarted LRCC and now LRCC says I have 4Gb required, 0Gb cache and 313Gb free.  Windows says I have about 65Gb free.  When I chose to NOT have local originals it did nothing to the originals files, The size of the originals folder on the external drive and the size of the folder on my computer are exactly the same to the byte.  I'm afraid of deleting the local folder where the originals are.  Shouldn't LRCC manage the space and delete the local originals now that I have chosen not to have them locally?

I just went ahead and deleted the local folder for the originals.  I'll keep the copy on the external drive for awhile in case I need it.  I restarted LRCC and opened one photo.  I looked at the cache folder location that I deleted and LRCC recreated the folder and it was only 4Mb.  LRCC had rebuilt the year/date folder structure and it contained the file of the photo I opened.  Not surprised, it still needs a cache location to do its work.  Now LRCC says I have 313Gb free and Windows says I have 283Gb free.  I'm guessing LRCC is still using that 30Gb  space somewhere it is counting as free space.  And I'm guessing it is in 
C:\Users\[UserName]\AppData\Local\Adobe\Lightroom CC\Data
because that folder is 30Gb.  Could be a coincidence. 
I will increase the size of the LRCC cache setting and try working with it for awhile to see if I have lost much performance.  If I need to I will turn on the local smart preview option, I've heard it works well.  
I'm still disgusted with Adobe for not getting the disk space numbers right.  And I am especially disgusted with them for not making it easier/obvious how to really clear that disk space when UNselecting the Store all originals locally option.  If their intent is to make photo management more intuitive and less dependent on operating system intervention they haven't got it right yet.

Same problem for me, and since all the time I use LRCC. I deleted and reinstalled the software, same problem... currently Lightroom believe's I have 130GB of free disk space; My setting is set to 10%, which would make you assume Lightroom should use 13GB, right? But no, when I look at the library in finder, it's currently at 75GB. It is truly sad to see one of the biggest software companies not being able to fix such a seemly clear issue.
