Hard Disk full after using AI Denoise Lightroom

Hello,

It's been a few days that I'm using the new denoise AI tool, after a while I relised that my hard disk was completely full (I'm talking about many GB for fixing only a few photo). I'm a Windows user.

The main problem is that I cannot find any file on the file system. I tried unistalling Lightroom but that didn't solve solve anything, do you have any suggestion?

Thanks

Windows

And another members post, that sounds a lot like my point about the Camera RAW CACHE size limit and location:

https://community.adobe.com/t5/lightroom-classic-discussions/lightroom-filling-up-c-drive-with-previews-and-history/td-p/14317699

The AI DeNoise, being a Develop Module mos, will be using that Camera RAW CACHE. If that Camera RAW CACHE is on the C drive, then that is what is probably what is filling up. Note that the Camera RAW CACHE does not purge itself, nor does LrC purge it.

1. What hard drive is full? Your C drive? a different drive??

2. Do you have other hard drives?

3. What hard drive is your catalog on?

or

4. On that hard drive, how much free space in %, looking for at least 20% free, some say 25%.

So in example, what, about 60% free.

5. What hard drive is you Camera RAW CACHE on, and how large? Example screenshot below is a good place to determine:

Thank for answering.

I'm talking about the C: drive. I was using it for the catalog, but even moving it on an external drive I got al the memory full again.

There's something wrong that is happening in the folder user. If i look at the size of the user is 74,7 GB. But then if I get into the folder and I select all the folders and documents inside is just 8 GB

I can tell for sure that is Lightroom the problem, because it's happening while using the AI Denoise.

Yeah I think I agree with @GoldingD here. I don't think you can reliably run Lightroom any version when you only have a 128GB system drive. There is just not enough space on there for the virtual memory, the Lightroom cache (although you can move that to another disk), the system and the program itself. Even 256GB is pushing it. I would never try to run the current Lightroom versions on a system with less than a 512 GB system drive.

Adobe support couldn't solve the problem, fortunately Microsoft did it.

It was definetly an Adobe issue, even if they told it wasn't. Microsoft made me install TreeSize, an app that was able to show folders not visible on the normal file system.

By the way, now with 50Gb free on my hard disk I can work fine. You can have 1000 TB on your hard disk but if Lightroom fills all of them with dump, and you can't see where the source is, you're not gonna be able to use your PC anyway.

Thanks, anyway

Probably unrelated to the AI denoise if you only did a few photos, especially if you are using the latest classic version. The AI denoise dng file that is produced is about the same size as the original raw image so basically 10's to 100 megabyte. Definitely not multigigabyte type levels.
