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

[Shoogamoogaman]

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.

How large is your C drive?

[Shoogamoogaman]

117 GB.

It's been very low on storage for a while, but hasn't been effected by premiere before because everything goes to either Data storage or my External Harddrive.

Nothing gets saved to the C: Drive when I use it.

I've been looking it up, it seems it might be a memory problem? As whatever storage was taken up, is reset after I close Premiere and restart the computer.

[Peru Bob]

You need a larger C drive.  You will likely run out of room for Windows updates.

[Shoogamoogaman]

I don't think that will fix this issue.

What seems to be happening is the more I work in Premiere, the more clips and images I import into the edit and such, the more the storage space of the C: Drive seems to be effected, despite the fact that I'm saving everything onto the External Harddrive.

For example, I will find an image online, save it into the External Harddrive, then take the image from the External Harddrive and import it to the project (the project itself also being saved in the External Harddrive). Then once it's imported into the project and I've edited it (i.e. changed the scale and positioning to make it move and rotate etc.), I'll look at my files and the C: Drive will have lost 2GBs of storage! Despite having not touched the C: Drive in the process.

THEN, once I've saved and closed Premiere, the C: Drive will reset, and all storage that was lost, will now be restored. UNTIL  I open Premiere again and the whole thing starts again.

This never used to be an issue, the C: Drive would never fill up while using Premiere Pro and I've been using it for the past 2 years, but now this happens and if I use Premiere for too long, the storage will fill and Premiere will crash.

I think it's the same for Photoshop too, but since I'm not importing files into Photoshop as often as Premiere, it doesn't fill as quickly.

How much RAM do you have?

You may be running out of RAM and your C drive is being used for virtual RAM.

[Shoogamoogaman]

Hi, how do I check the RAM and fix it?

This seems like the only explanation that fits so far.

I've created more storage space on the C: Drive but as expected, it continues to fill upon use, and resets upon closing the programme, just takes longer to reach maximum now.

Have you double checked your scratch disk settings? (File > Project Settings > Scratch Disks)

These can sometimes be changed after trashing preferences or updating, which would explain why the issue popped up recently.

[Peru Bob]

I don't think it is a scrach disc issue, as closing Premiere Pro and restarting the computer results in the release of the C drive space.  The media cache files should not be deleted just by closing and restarting.

I find myself in the same situation. The size of RAM and C Drive shouldn't be the issue here, when everything used to work fine before a recent update, scratch disks are appropriately allocated to a significantly larger drive and none of the user-accessible settings in Premiere Pro are pointing to the C drive.

Somerthing fills the C drive in the background while we work. I've used a TreeSize to pinpoint that the C/Program Files/Adobe/Adobe Premiere Pro 2020 folder keeps filling with .dll files while I work, (Plug-Ins folder, Presets, etc). Another folder that fills up constantly is the C/Users/[username]/AppData/Roaming/Adobe/Common/Media Cache Files folder (even though none of my project setting point there (see screen dump of the only project I've been using for the past few days).

Does anyone know how we can stop Adobe products from laying seige of C drives? I'm losing my motivation to keep up a subscription when I have so much trouble getting things to run smoothly.

[tonia5ED3]

Having the same problem. Any replies from Adobe? Thinking of going back to avid.

[default1j1am8yhcbvb]

More than a year later and the problem is still there. Good service, Adobe. As a new customer, i will definitely cancel my subscription as soon as possible, since these type of problems are just ridiculous. Up to 10 gigs on drive: c keeps disappearing while i am working, even though i keep everything on a separate drive.

More over, Premiere sometimes resets these settings (media cache folders ) and simply destroys drive:c leaving no space there upon opening heavy projects.

I dont mind 1 gig to disappear/re-appear from time to time if that is the secret nature of Premiere that you cannot fix for years , but not 10 gigs and up, this is a big NO.

[default1j1am8yhcbvb]

No, it takes way more than 10 gigabytes at times. Atrocious.

It's seriously infuriating that Premiere can just take up your available boot drive storage for VRAM with no ability to regulate how much you give it. It takes, it and doesn't reallocate it like it should. It just endlessly pulls putting strain on the machine, making everything run like crap. 

I hate that Adobe does this so much.
