Large amounts of dat Cache files and a smaller number of dat Index file on my D Drive

[mrnikond800]

I have a PC running Windows 10 with 32 gb of ram and three hard drives. The Photoshop 2020 program is on the C drive which is a 250 gb ssd. I shoot Nikon NEF files and process the raw files via Bridge and the Adobe Raw Converter. The other 2 drives are terrabyte hard drives.  The scratch disk order is D, E and C drives.  My images are stored on the E drive.  All drives are less than 50% full.  The problem is I keep getting large amounts of dat Cache files (eg. Cache_00_0000000020.dat) and a smaller number of dat Index files (eg. Index_06.dat) on my D drive when ever I use Photoshop.  After a recent Photoshop session I had 796 cache.dat files taking up 308 mb.  My wife has a similar system except she only has 16gb of ram.  She also shoots Nef and uses the same Adobe programs to process her images.  She does not get the dat. files building up on her machines.  Does anyone know what is causing this problem and how can I overcome it?

Thanks

I have the same issue.  Did you ever find an answer?

I´ve the same problem, searched some blogs and forums, but Adobe do not answer on those questions.

Adobe, are you there? Please answer, why dat files are created and how users can avoid this.

Thanks in advance.

I've seen that a very few times, one pretty recently. I open a drive and all these files sit at the root of the drive.

You can just delete them.

I have no idea what it is. Just happens once out of the blue, then nothing after I delete them.

Thanks for answering! Every time these files pop up, I delete them. Deleting is not the problem but those files building up, again and again. Each time I´m opening a photo via Bridge in ACR. One opened photo generates 3 dats and one cachfile or so.

It´s annoying.

It is if you're getting it constantly. I only get it once in a blue moon -

You´re a lucky one... ;o)
