Premiere Pro keeps filling my C: Drive while in use.

Report · Jan 10, 2020

I haven't had this problem until now.

Basically, whenever I try to edit a project on Premiere Pro now, my computers C: drive begins to fill.

I don't have a lot of storage there so I can only use premiere for a few minutes at a time before the lack of storage begins to mess with the software.

This has never been an issue before, as I have my media cache set to my Data Drive and all images and clips saved in an External Harddrive.

Yet this issue persists.

When I stop using Premiere and restart the computer, all space that was taken up is reset, as if nothing happened.

What is going on? How do I fix this? This has never been an issue until yesterday.

Has anyone found a solution? this is so frustrating and is limiting me from doing my job????

Thanks.

What are the complete computer specs, including hard drives (how many, what kind, what is on each, what capacity, and how full)?

Also looking for a solution regarding this.

I'm having the same issue for both After Effects and Premier Pro.

My C Drive has 40GB free. When I open either aformentioned programme, I'm immediately told with a popup that the Media Chache is running low on space, I check my File Exploerer, and those 40GB I had free has reduced to 10GB free. And I'm not doing anything crazy, I have a few compositions plus 3-4 media videos that are no more than 30MB each.

Today I even got a warning from my computer that my C Drive was running low (while using after effects). I check it in File Explorer and I'm running with, and I kid you not, 993MB free on my C Drive.

I closed After Effects and only 20GB have returned.

Am I doing something wrong here? Is there some sort of setting I'm meant to turn on or off?

I can confirm that I am having the same issue...so still not fixed by Adobe.

I have assigned external SSD for cache, previews, scratch disk, etc. but as soon as I open my project, C drive takes away like 20-25 GB space.
Then while rendering, this keeps on reducing further so PrPro ends up taking like 50-60 GB on C drive (including rendering) even when I have assigned above stuff to external SSD.

Isn't this a result of poor optimization / coding of the program?

What elements of PrPro are using up this much of space unnecessarily?

I have 32 GB of RAM so for other applications I have reserved 6 GB which seems ok to me. And it does not consume all RAM even while rendering...8-9 GB is always free.

I think it's high time that Adobe must look into this now. Please allocate more resources to resolve these basic but annoying issues (rather than spending too much on marketing new features / AI stuff).
Maybe use AI to fix disk space issues 🙂

On a side note, as an example, there is a video game called Hitman World of Assassination that you might be familiar with.
How they managed to compress part 1 & 2 (> 170GB of data) into 70-80 GB is really impressive. They used something called LZ4 compression.

Maybe Adobe should research & look into something similar to reduce project footprint on C drive. At least let us know what mysterious elements are using up C drive space and give an option to assign it to external drive.

Let's start a new campaign #savecdrive
