Camera Raw generates .acr files when editing

[cm64746914]

When I edit any RAM file of my Sony A1, A9II and A7III cameras with Camera Raw (latest version) and I apply a preset to that photograph, either color or focus, it generates and saves an .acr file (171 kb) apart from the . xmp always in the folder where the photographs are, I already talked about this issue a few months ago with the upper department of Adobe and it still hasn't been solved, does anyone have a solution to this?

My computer is iMac 27 Retina 5K with masOS Big Sur 11.5.2 with a 4.2 processor - Intel core i7 of 4 cores with 48gb ram and graphics a Radeon Pro 580 8GB

Making one of the new masks? That's probably what you now see:

Without making masks it also generates and saves the .acr file.

There isn't anything to solve. This is supposed to happen when you use the new maks/adjustment features.

It happens without wearing masks!

A .acr file contains non-textual data (binary). Currently that can be an AI-generated pixel-based mask and/or a LUT. Other items will be stored in this file in the future. 

I am guessing your color preset has a profile that uses a LUT (look up table).

If you generate it when using a preset, but because you don't save the editing data in the .xmp as usual, in a single file, it is very annoying to have another file when editing, with Camera Raw 13 that .acr is not generated.

The file isn't present in ACR 13 because the feature didn't exist then. These files are how Adobe stores editing data, there really isn't another good way to do it.

In addition to this, if you only use the masks it also generates that .acr file.

Okay, but what do we do now with the acr and sidecar files if I want to upload them as jpegs to my website?  

Thank you-

Normally, you don’t need to do anything about the sidecar files. Any LUTs, masks, or other edits in the sidecar files are automatically rendered into the exported JPEG copies.

If you are keeping your original raw files, then you need to keep the sidecar files too so that those edits are preserved for a future editing session, so you don’t need to delete or remove them. You just leave the sidecar files where they are.

According to Adobe It seems like the .ACR file contains the pixel versions of previously generated AI masks (Select Subject/Sky) so they don't have to be recalculated each time you open a raw file with previous AI masking elements. So it is needed to be there in an extra .acr file apart from the .xml, that is how they have designed it, generating more dirt in the folders of our computers, something with which I do not agree.
