"Media Cache Files" is a huge folder - is it necessary data or temporary data that I could delete?

My folder "Media Cache Files" (found in: profiles > appdata > roaming > adobe > common > media cache files) is currently over 200 GB big and I was wondering whether all of this data is necessary for my projects (or for anything else?) or whether it is temporary data that I can delete without causing any problems for my saved projects or the programme itself? Does anybody know? Thanks in advance!!!

Mylenium, Thanks for your immediate reply! This helps me a lot! ... and my laptop will be oh so happy to have less GB.

Why is this massive media cache file on my C drive?

Running Adobe CS5 (NOT 6) on a Windows 7 PC.
I thought I had made sure that everything was on my D or E drives since my C drive is an SSD and I don't want anything but the basics on it.
Well, I have nearly 4GB of Media Cache eating up SSD space and no way to know if I can delete it, how to delete it, how to move that directory, etc.
Whenever I start a project I have my source files on my E drive and I list my D drive as my scratch drive.
Here is a screenshot showing the exact location of this huge Media Cashe folder.
Gents, I'd greatly appreciate some assistance. My SSD is being eaten alive.
Can this stuff be deleted? If so, how? What exactly IS that stuff and why is it on the C drive?

Hi msp1518,
Thanks for the posting adobe forums,
These are the files for conforming audio, generating peak files for audio.
Yes, you can delete these files once you have completed the project in premiere pro.
Just, close the premiere pro : Just delete the files inside the Media cache files and Media Cache folder.

Sandeep

[BUG] Media Cache Files

Windows7 x64, SP1
Media Cache Files recreating each time when I open a project. But when I close Premier Pro- this folder was not cleared automatically. This is bug for end-user because this folder "eat" huge disk space.
Who know why and how it can be cleared? Only advanced users. And the rest will see "out of space".
You need to fix Premier Pro so Media Cache Files folder can be cleared after Premier Pro is closed.

If the cache cleared every shut-down, it wouldn't be 'cache'.
Clearing cache between projects is a fine idea. Here are some other thoughts on the subject.

Media cache files...

Hi
I have a folder on my C-drive under application data\adobe\common\ called "media cache files". There is a huge amount of data in that folder.
Can I put it somewhere else, and is it safe to empty it once in a while?
Thanks.
/Ulf

Render Files for your projects are stored there.
If you are sure you want to clean them up, choose Sequence -> Delete Render Files or Sequence -> Delete Work Area Render Files so as to do it safely.
Sweet cat btw

Do I realy need the Media cache files for archiving

Hi I am arc hiving some projects and the Media Cache Files are huge over 7GB. The project this is from is a 2hr dvd so I expect big files, but I can't fit 7GB on a data DVD for backup. Can I delete this cache folder and will Encore DVD 2.0 rebuild these files the next time I try to access the project?
Matt

I wouldn't delete any if it if you want to absolutely positively guarantee it all works later. However, the PK files and CFA files can be deleted if you like, and it shouldn't bother Encore too much. Next time you open the project they will be automatically re-created (no way around it), so take that into consideration as far as your time is concerned - you will have to wait while those suckers are re-built.
If you have transcoded assets, Encore can get fussy looking for them, even if you have the original untranscoded assets recognized. My choice...delete the CFA files and PK files and archive the rest for safety. The CFA files take up a huge chunk anyways, so that should help with 1 or 2 GB of space.

Media cache files: Premiere Elements 9 with SSD

Hello you fine Adobe people.
I apologize if this has been asked before, if so please could somebody direct me to an answer?
I have Premiere Elements 9 on Windows 7. My issue is pretty simple: my shiny new SSD is getting full of temp files from the "C:\Users\XXX\AppData\Roaming\Adobe\Common\Media Cache Files" location every time I work on a project. I have set all other cache items I can see in "Preferences" to my mechanical disk, but I am alarmed to see this folder filling up with huge files on my SSD. Aside from the unneccessary reads and writes, it will be filled up in no time. It seems in Premiere Pro you can direct this folder to an external drive, but I cannot find this option in Premiere Elements.
Please tell me there is a way to move the media cache files directory to another drive than C:\ ?
Thank you in advance
A Craven

The answer is that you need Premiere Elements answers for Premiere Elements questions.
The conformed audio files (cfa and pek) are stored in the Media Cache Files Folder. By default, that folder is found in Windows 7, 8, or 8.1 64 bit.
Libraries/Documents/Adobe/Premiere Elements/10 (if 10 is your version). You set the save location for the Media Cache Files Folder in Premiere Elements Editor workspace Edit Menu/Preferences/Scratch Disks and the "Media Cache" category.
The conformed video files (mcdb) are can be accessed via the Premiere Elements Editor workspace Edit Menu/Preferences/Media and its Media Cache Database area. There you will find a Clean up to clear them and set limits. The actual files (which have a .mcdb file extension) can be found via the path shown in that area. This appears to be an unchangeable location.
Preview files from rendering of Timeline content to get the best possible preview at play back of the Timeline content in the Edit area monitor are stored in the Adobe Premiere Elements Previews File Folder. By default, that folder is found in Windows 7, 8, or 8.1 64 bit Libaries/Documents/Adobe/Premiere Elements/10 (if 10 is your version). You set that save location for the Adobe Premiere Elements Elements Previews File Folder in Premiere Elements Editor workspace Edit Menu/Preferences/Scratch Disks and the Video Previews category.
Please let us know if you are now clear about Premiere Elements and how it relates to Media Cache et al.
Please ask if any further questions on this or need clarification.

What are the advantages/disadvantages to "Save Media Cache files next to originals when possible?

I just noticed that I have over 7,000 files and 46.7 GB in my Media Cache Files folder. I know I can just delete all the files in this folder and Premiere will automatically rebuild the files when needed. But, are there any advantages or disadvantages to saving the files next to the originals? I assume that means that it will write these files wherever I'm storing my media files...

I'd say storing your cache with your media would decrease your performance. Having them on separate volumes/drives means that Premiere can read/write from them at the same time, instead of having to read/write one or the other, one at a time.
Additionally, PPro is create cache files from your original media, and it's always best practice to read from one drive, while writing to another.
TL;DR It's for Performance. ! ! ! !

Media Cache Files? Do I need them?

I was checking what's taking place of my hard drive and found about 22 GB of hard disk space occupied from this folder
C:\Users\Me\AppData\Roaming\Adobe\Common\Media Cache Files
In this Media Cache Files folder there were 459 files of type .cfa and .pek files. 13 of the .cfa files were about 1.6 GB size each
What are these files for and do I need to keep them?

Read about 'em:
http://help.adobe.com/en_US/premierepro/cs/using/WSa41b87baf39dd9b0-4a7aee25125bce32690-80 00.html
Bottom line, if you clean the media cache using one of the apps (Encore or Premiere for example) and the source files are still on line, it won't delete them. You can manually delete those pek and cfa, and if you open a project with those files, it will recreate them.
Note that Encore help only says:
Clean Database . Frees up additional disc space by removing old files in the media cache database shared by Adobe audio and video applications. The database tracks media accelerator files that improve performance and speed. For example, if Adobe Premiere Pro creates a conformed audio file, and you import media with that audio into Encore, Encore uses the file from Adobe Premiere Pro instead of creating a new conformed file. The media cache database informs Encore of the conformed file’s location.

CC 2014 Media Cache Files duplication...

Windows 8 Pro
CC 2014
3930k
Titan Black
SSD C:, raid, and storage
As of the latest update for CC 2014, any time I open any audio file from CC with Audition it is now saving a PFK and Extracted audio file next to the original in addition to the folder I have designated for these files.. I do NOT have the box checked for "Save media cache files next to originals when possible".
I didn't notice this problem until almost finishing a very large project with hundreds of sound effects that now have PFK files and Extracted files sitting next to them all over my effects and music folders.
This problem is NOT happening is plain old CC... only 2014.
I have tried pointing it to a new folder, and have also tried checking and unchecking the box.
Anyone else have this issue? Any possible solution I have not tried?
Thanks

Win 7 64
CC 2014
3930k
Titan Black
All SSD
64 gigs ram
Exactly the same issue as Jeckle. Without having the box checked "save media cache files next to originals", every single file I've imported into 2014 has created a pkf file directly next to the original, as well as in the location I specified for the cache. This is eating my drive space pretty quick. Anyone?
Tested with fresh project file in both CC and CC 2014 - no problems at all with CC...
Any help appreciated...

How can I tidy up Adobe Media Cache files

On Windows Vista, I have a a C drive of 92GB. However, 33GB of this is taken by thousands of files in
users/me/appdata/roaming/Adobe/Common/Media Cache Files
with extensions such as .cfa & .pek
How can I free up the space used by these?

JohnJRP01
What version of Premiere Elements are you using and what is your Windows Vista 32 or 64 bit?
If you are looking to regain some more free hard drive space, please consider.
1. Removal of the preview files. If Adobe default, then Documents\Adobe\Premiere Elements\version number of Premiere Elements\Adobe Premiere Elements Preview Files Folder.
2. Removal of conformed audio files (cfa and pek sets), then Documents\Adobe\Premiere Elements\version number of Premiere Elements\Media Cache Folder.
3. Removal of conformed video files (.mcdb), then Local Disk C\Users\Owner\AppData\Roaming\Adobe\Common\Media Cache
Running the ccleaner (regular and registry cleaner) for overall computer optimization (be sure to say Yes to backing up registry before the registry cleaning...never had any problems, but good to be safe).
http://www.piriform.com/ccleaner
Good idea to check Edit Menu/Preferences/Scratch Disks for the reading of available space at the location to which they are directed.
General thought...check out Adobe Folder Media Cache for cfa and pek and that Common Folder via the Users directory for .mcdb unless you have custom locations. Check periodically to make sure that the Scrath Disk Locations have not changed without you knowing it.
Also, go easy on System Restore since the process eats up a lot of hard drive space.
Thanks.

Do I need all those media cache files in my user profile?

Hello Forum,
When I installed Win 7 and Adobe Production Premium on a 120Gig SSD, I made this mistake of not putting only the essential part of Windows on this System and Apps drive. (I have separate 1Tb HDDs for media and rendering, and work with compressed HD files). I noticed that my user profile has grown enormous, to the point of filling up the SSD, and when I searched to see why, the main problem is a substantial accumulation of media cache files in the folder...
user/App Data/Roaming/Common/Media Cache Files
Judging by their names, sizes, and dates, they seem to pretty much replicate all my raw media files on my media HDD, from all the projects I've done since last summer. This folder is about 40 gigs.
So what is the function of this media cache folder? Can I move it, or direct PP to put this stuff on some other drive than my SSD? Do I even need the contents of this folder? All my scratch files go to the F: Rendering HDD.
Thanks.
PS: If any of you have suggestions on how to move my user profiles off the boot/apps SSD to one of the HDDS, without reinstalling everything, I'm all ears.

To follow up, I now see this is a product of running AME, and AME gives me options of where to put all this stuff. Can I just change those options to my F: Rendering Drive, and move the contents of this folder there?

How to manage media cache files in Premiere Pro CS5.5?

I hope my question is not too complicated but I still haven't figured this one out.
Here goes:
Whenever I open a project in Premiere Pro, the media cache files used are always the same ones from a prior project.
For example, if I open project ABC, the scratch disk used, the media cache and media cache files are from the ABC project file.
Then, if I open another document, XYZ, the scratch disk and the media cache files are again stored in the ABC project file.
HOW DO I CHANGE THE SETTINGS SO THE SCRATCH DISK AND MEDIA CACHE ARE THE ONES SPECIFIC TO THE PARTICULAR PROJECT I OPEN?
So I don't have to move all the cache files manually or change the settings in Premiere every time I open a project.
Sorry for the long description. Thanks for your help. Daniel Martel. Quebec. Canada.

You can't (unless you want to store them next to the originals, a proposition I find untenable). Some of the scratch disk settings are stored at the project level (things like video and audio previews), but the one's you're talking about are global - one setting for the whole program.
I don't like that arrangement myself. ALL scratch disks should be stored per project.

Can I delete adobe/common/media cache files?

I've a seriously shrinking hard disk. Have found 20 gig of data in my Home/Library/Application Support/Adobe/Common/Media Cache Files.
Am I right in assuming I can safely delete these files and if I need them again, all apps that created them (e.g. Adobe Premiere Pro etc) will just rebuild them?

I recommend you to use specific software like Onyx or CleanMyMac to delete cache files. These programs aren't perfect, but it's very difficult to have a problem with them.

Media cache files do I check the save media box

I am trying to optimize my system and under the preferences under media it is set to the default on the C: drive. Here is my setup I have a 1TB C:\ for OS and programs and four 1TB drives setup Raid 5 which is my D:\ drive and 24GB of Ram. If I understand correctly I should set my Media cache files and Media cache Database to the D:\ drive? If I check Save media files next to originals dose this do the same thing? Also with 24GB of ram what and where should I set my pagefile to?

Your raid is nearly three times faster than your boot disk, so I would put the media cache files next to your projects on the raid. With 24 GB memory, the location of the pagefile is not really important, since it will hardly be used, due to the good memory management of PR. If you use on-board IHCR, you may put the pagefile on C because the IHCR is pretty slow in comparison to a dedicated controller.

Lightroom 5.3 Media Cache Files

Hello,
I want to save in Lightroom 5.3, the Media Cache files in a different directory. I have Lightroom and PS CS6 installed on a 60 GB SSD and the media cache files quickly take 10 or more gigabytes.
In the registry as DatabasePath and FolderPath is set:
[HKEY_CURRENT_USER \ Software \ Adobe \ Common LR5 \ Media Cache]
"DatabasePath" = "C: \ Users \ Username \ AppData \ Local \ Adobe \ Lightroom \ cache \ Video \"
"FolderPath" = "C: \ Users \ username \ AppData \ Local \ Adobe \ Lightroom \ cache \ Video \"
If I change the path in the registry is Lightroom the path when playing the first video unfortunately always come back.
How can I change the path permanently.

Leider kann man in den Voreinstellungen nur die Video Cache Größe bestimmen aber nicht den Speicherort. Somit könnte ich die Video Cashegröße auf 1 GB "minimieren" und habe für Videos immer lange Wartezeiten wenn ich sie abspielen / bearbeiten will. Das hilft mir also leider nicht weiter.
Den Speicherort kann ich in den Voreinstellungen leider nur für die Cache Dateien von Bildern freiwählen und das funktioniert auch prima.
Im übrigen habe ich die Einstellungen für die Media Cache Dateien für PS CS6 auch in der Registry geändert und das Auto fährt noch prima und ohne Probleme.

"Media Cache Files" is a huge folder - is it necessary data or temporary data that I could delete?
