Preview files folder

a folder of media encoder preview files is created in my documents- adobe- media encoder
this folder is getting bigger, I think every time I'm using media encoder to export my projects
at the moent it's 30 gigs after less than a month using CC
I need to know if I can delete this files? and I need to redirect them to my D drive or even better not create preview files

Thank you for your answer.
Trouble is I know how to clean the Cache but it was the Preview Files that were the problem.
Additionally, I have some Cache Files in the location below which are taking up 23GB
User>Library>Application Support>Adobe>Common>Media Cache Files
There is also a folder here called Media Cache.
I am confused becuase I have set my Media Cache Files and Media Cache in Premiere Pro, After Effects, Media Encoder to all be the same and none of them point to this location? How do I clean this folder? Is it only present from a previous versions of the applications and simply not been removed when the programs were uninstalled? A lotof the files here seem to relate to audio files and .pek files?
Really grateful for your help on this one.

"Adobe Adobe Media Encoder Preview Files" folder full ?

Hello,
I'm on latest version of both Premiere and Media Encoder, I'm working on PC/7 (64bits)/i7/Cuda,
What is "Adobe Adobe Media Encoder Preview Files" folder ?
C:\Users\XXXXX\Documents\Adobe\Adobe Media Encoder\Adobe Adobe Media Encoder Preview Files\7.PRV
How to purge it NOT manually ? Why is it created ? How to deplace it or remove it ?
I've plenty of videos into my batch, and as soon as this folder is full, it's not exporting anymore. Even if all the old previewes are used and exported, they are not removed or automaticly deleted.
I've tried to move this folder of my D: through adobe media encoder preferences... impossible to find its reference somewhere.
If you have any idea, thanks a lot

Bonjour,
je suis sous la dernière version de Media Encoder CC 7.2.2.29 (je suis abonné au Cloud) et j'exporte via file d'attente sous premiere CC.
J'ai le dossier suivant :
C:\Users\XXXXX\Documents\Adobe\Adobe Media Encoder\Adobe Adobe Media Encoder Preview Files\7.PRV
qui s'engorge et ne se vide jamais, et donc sature mon disque dur OS et software sous C:
Je n'arrive pas à délocaliser ce dossier, via les préférences de Media Encoder par exemple.
D'ailleurs, je me demande même le pourquoi de son existence, et encore plus, pourquoi ne se vide-t-il pas lui même lorsque l'exportation est finie.
J'ai un batch de vidéos énorme à exporter, du coup, il sature le C: et du coup, je me lève le matin et seulement la moitié de mes exportations sont faites. Sympa pour mes deadlines.
A noter que :
- via les préférences de media encoder, j'ai désactivé les previews (la petite fenêtre qui permet de voir l'évolution et progression de la vidéo sous encoder), ça change rien.
- ce dossier ne se remplit évidemment pas, lorsque j'exporte directement via Premiere, sans passer par la liste d'attente de media encoder ("exporter" et non "file d'attente" donc.)
- je coche systématiquement sous premiere "rendu à la résolution maximale", "utiliser la qualité de rendu maximal" (jamais compris le pourquoi de ces deux trucs d'ailleurs, j'ai jamais l'impression que ça changeait un truc) et "utilisez les prévisualisations" (qui sont déjà rendues en vert, évidemment)
Merci pour vos lumières !

Media encoder preview files folder

Hi!
I'm not sure this folder exisited the last version, but in media encoder CC it's there in my documents/adobe/media encoder preview files.
the problem is that it's getting realy big- 30 gigs. I'm not sure why is it created.
I want to know if I can delete those files and I realy need to change it's path so it wont block my c drive
thanks

If you are using a SSD there are likely to be a few very large files that you would like to relocate, not just those belonging to Adobe.
I too found that media encoder files within ‘c:\users\[ME]\My Documents\Adobe\Adobe Media Encoder\Adobe Adobe Media Encoder Preview Files\8.PRV’ with no obvious way of adjusting the settings to move them.
The solution I usually use for this type of problem is to create what is known as a ‘Windows Junction’, which is like a ‘shortcut’ but behaves exactly the same as a regular folder. I decided to move the whole of the ‘c:\users\[ME]\My Documents\Adobe’ folder from ‘My Documents’ to the root of another disk drive and then create then replace this with the ‘junction’ named ‘Adobe’ in . ‘c:\users\[ME]\My Documents\’
1: Close all Adobe software in case anything is in use in the Adobe folder (or the move will fail).
2: I was going to suggest moving the files at this point but it may be safer to copy them and then delete the ‘Adobe’ folder only if the copy is successful. Copy the Adobe folder to another drive using drag and drop, in this example I used the root of the ‘G’ drive. If the move is successful delete the original ‘Adobe’ folder from ‘My Documents’.
3: Start a command prompt window in administrator mode (right click / run as administrator)
4: Change the directory to your ‘Documents’ folder using the command (not My Documents):
CD “c:\users\[me]\documents”
Replace [me] with your folder name, which is usually your name
5: Assuming you moved the ‘Adobe’ folder to the ‘G’ drive, and replace ‘G’ if different enter the command:
Mklink /j Adobe G:\Adobe
I have put multiple spaces in the above where there must be at least 1 space.
I have used this solution to move parts of ‘program files’ and other folders from the SSD to a regular hard drive for software and files I do not use very much.
Maybe I should make a video of this procedure?

How to set directory for preview files?

I have my Media Cache folders set to an external hard drive, but Premiere Pro still continues to create hundreds of rendered preview files in the default location of Users/username/Documents/Adobe/Premiere Pro/8.0/Adobe Premiere Preview Files, filling up my main disk and then crashing when it gets full. Is the preview file folder a separate setting somewhere?
Mac Pro 5,1, OSX 10.9.4

I am having a problem with this as well since installing 8.0. PP 7.2.2 and previous versions did not have this issue.
When I set the Media Cache preferences to store all cache on an external hard drive it will in fact do so with the exception of IMS files which it still puts in the default of C:\Users\USERNAME\AppData\Roaming\Adobe\Common\Media Cache Files.
Win 7 Pro
PP CC 2014
2014.0.1 / 8.0.1

Premiere Pro CC not creating preview files?

Hi there,
I'm working on a project in CC 2014 and when I play a timeline, I either get 'media pending', a black screen or some strange lines as if only a few frames of the clip have properly rendered. When I try to render the timeline, I get "Error compiling movie: unknown error". There are also no preview files in the project preview file folder (despite that folder being the allocated folder for preview files).
I've tried importing the sequence into a new project and the same issues carry on.
Any ideas?
Happy to provide any more info to help!
Cheers

As the faq for all the Adobe forums notes, it's handy, useful, and basically polite to start by noting your computer's specs: OS, chip/cores, RAM, video card/s/vRAM, disk setup, and also the specific software build you're using (to the dot-x level) as quite often this data gives a big heads-up to the answer of a question to start with. Next, it's also useful to give your codec/s, frame-size, and a hint of experience level and whether or not this is the first time you've tried something or whether you've done it for only 10 years a million times but THIS time it fritzed for some reason.
I can help with basic things but before anyone else even more helpful than moi can help ... they'll need more info.

Should I delete preview files to save space on my hard drive?

Should I delete preview files to save sapce on my hard drive? At times the program crashes and I wonder whether I should get rid of these files to make more space.

PCNoviceMesa
Yes.
If you run a SD project (whether you render stills or videos) and render, you are going to get DV AVI files automatically generated. If it is a HD project, rendering deposits MPEG2.mpg files on your hard drive (whether you render stills or videos). We are talking possibly GB amounts of files if you let them pile up long enough. For Windows 7, 8, or 8.1 64 bit, these preview files are by default in Libraries/Documents/Adobe/Premiere Elements/12.0 and in the Adobe Premiere Elements Preview Files Folder there.
First let us see how much is piled up there before we take action against them.
If the preview files there are part of an existing project or projects, the consequence of deleting those files is that you will have to render again that content in the project to get the best possible preview. If the preview files represent project long since gone, good riddance.
Please check out the situation. And, then we can discuss also pile ups of conformed video and conformed audio files.
More later.

Rebuild PremierePro project using Preview Files?

I'm using PP CS6 on a Mac and I have lost my original video files (long story but they are gone). The timeline still has the audio but instead of the video, I get a red screen missing media message.
However, in the Preview Files folder, I can see the full res previews from the entire project. Is there a way I can ask Premiere to use these preview files to rebuild and export the project?

Unfortunately, no.

"Premiere Pro stores the preview files in a folder you can specify" But how?

Specifying a Preview folder
On page 265 of the PDF it states:
Premiere Pro stores the preview files in a folder you can specify.
QUES 1
But how do you specify the folder? I just rendered a test clip and was not offered the option of specifying a folder. And there is no other mention of preview folders in the PDF.
Preview Files for Encoding
On the same page is:
Note: Adobe Media Encoder does not automatically use Premiere Pro preview files for encoding. To make use of the Premiere Pro preview files, you must select the Use Previews option in Adobe Media Encoder for each encoding process.
It is not clear from the PDF what is the quality of these preview files.
QUES 2
If I select the Use Previews option when exporting, aren't I degrading the quality of the export by encoding from an already encoded preview?
QUES 3
For the absolute best quality, should Use Previews be turned off?

Preview File location is determined in the overall Project Settings.
Set this location before you render any Preview Files.
Project > Project Settings > Scratch Disks...
Some documentation regarding the Scratch Disk location is buried here:
Specify scratch disks to improve system performance
QUES 2
If I select the Use Previews option when exporting, aren't I degrading the quality of the export by encoding from an already encoded preview?
In most (if not all) cases... yes.
Previews are intended for real-time playback in the Timeline only.
You should not use previews for export.*
QUES 3
For the absolute best quality, should Use Previews be turned off?
Yes!
*There are a few semi-obscure exceptions to this general rule.

Add a button to activate or not preview file in the folder

Is there a way to do this thing?
I'd like to add a button at the top of the finder windows to quickly able or disable preview files in the specific folder.
Thanks
Massimiliano

Open a Finder window, select View->Customize Toolbar, and add QuickLook button to the toolbar. The only other way is to invoke CMD+J and turn off or on icon preview.

I have the latest downloadable version of LR5. It crashed while it was createing 1:1 previews during an import. After a Win7(64) restart, it shows a message that LR needs to quit because it can't read the preview files and it will try to fix it the next

I have the latest downloadable version of LR5. It crashed while it was createing 1:1 previews during an import. After a Win7(64) restart, it shows a message that LR needs to quit because it can't read the preview files and it will try to fix it the next time is launches. I get the same message the next and every subsequent time it launches so I can't launch LR at all now.
I get that the preview file got corrupted somehow. Is there some way to fix this problem without building a new catalog?

Use Windows Explorer to open the folder containing your catalog. You will see a folder with the extension .lrdata. You need to delete that folder and then start Lightroom again. Lightroom will generate a new previews folder.

Saving a book as a PDF file in 5.04 becomes a preview file

In iphoto 4 i would create lovely books then save as a PDF file which saved as an Acrobat Reader file and opened up just like a book. when i save as a pdf i am getting a preview file
not what i want! how do i get the acrobat reader back?? anyone????

Slideshow can be saved as QT movies but they would be way to big to email. If you can get them to a Windows machine it can view them if they have Quicktime for Windows installed. It's a free download from apple.
There's two ways to backup your library. The first is to save the entire iPhoto Library folder intact. Obviously that will keep all of your data intact, meta, iPhoto organizational, etc. It has to be small enough to be saved to a CD or DVD disk.
The other way is to burn to disk from within iPhoto portions of the iPhoto library, by albums or rolls, to disk. This will preserve any keywords, comments, and other organizational information that is in iPhoto.

Can't add file to baggage files folder

Hi,
I have a javascript file I'm trying to add to the baggage
files folder. However, for some reason, I can't add it. I'm using
robohelp 6 and roboosource control 3.0. When I try to add the file,
nothing is added to the folder. I was able to add the same JS file
to another project that was created in X5. So I'm unsure what the
prolem is.
I manually added the javascript file to the rhbag.apj file
but it still doesn't seem to recognize that this file is added to
the baggage files folder or project. I'm still getting a javascript
error as if the file is not in the project.
Strangely enough, when I tried to add the javascript file
from the other project's folder, it asked me if I wanted to
overwrite the js file. But it still doesn't appear in the baggage
files folder or in source control.
Any help is appreciated.
thanks
--Brad

Hi Rick
Sorry--I guess my previous response wasn’t clear. I did
physically copy the JS file to the local project folder first. I
didn’t think it would magically appear.
In terms of the .apj file, I edited it—adding
the code for the script from another project’s apj where the
same script is working—and saved it. But it’s still not
adding the js file to the baggage files folder or to source
control. When I view the apj file that’s in source control,
it has the js code in there.
I then tried overwriting the apj with the apj from a project
where the script is working (that’s what I meant by
replacing), but that didn’t work either. To add another
twist, the script runs without errors in preview mode, but not in
the compiled html help.
I’m unsure what’s wrong with this project as this
script is successfully working in other projects and visibly
appears in the other projects’ baggage files folders. I hope
this was a little clearer.
I’m open to any other suggestions.
Any questions, let me know.
Thanks
Brad

Can Prelude use the MXF preview files instead of the full size files?

It takes forever to load and view my full size MXF files from an XDCamHD disk. (It can also cause Prelude to crash) It seems like it would be very helpful to be able to view the tiny preview files contained in the "Sub" folder. You could quickly review your media, decide which files to transfer and then do so with the originals. Has anyone been able to see those files in the Prelude Ingest window? I only see the file icon, not the video media.
I had been using the Sony XDCam Transfer App with Final Cut, but am now trying to create a better workflow all inside Adobe software.

Hi AEDave -
Thanks for your post.
Wanted to share that we have been working on the performance with the XDCAM optical disc thumbnail load times (as well as other performance enhancements for this format). We are seeing a nice improvement on that front in our recent testing. And as Wes mentioned above we are also looking into how to best handle the proxy files the camera generates as well. Just wanted you to know we have improvements in the works for your workflow!
Thanks -
Michael

How do I change the preview file location?

I have a SSD "C:" drive which is filling up, and I have other drives with lots of space and performance, so I'd like to move where SB stores the preview files (currently in "Adobe Soundbooth Preview Files") to a different drive.
I haven't seen anything in the SB config which allows me to do this, is there a way, and if so - what is it?
Thx!

(1) Open a new tab to about:config (type about:config in the Awesomebar and tap the go arrow or tap Enter)
(2) In the search box, type down and tap Enter
(3) Scroll down to browser.download.folderList and tap Modify, then change the value from 1 to 2 (from default always to last used folder). The change should appear after a few seconds.
(3) Scroll back up and tap the "Add a New Setting" button
(A) String is the correct type, so OK that
(B) The name of the preference should be browser.download.dir (this stores the last used directory)
(C) The value should be /sdcard/ followed by the folder name you want to use, for example, /sdcard/FxDown

Preview files

Hi. A couple of things with previews.
Is it normal to have a 1 folder with 1 file in it for every preview in the preview directory ? If you delete images does the preview file and folder get removed also. I seem to have more preview folders than images. Some of the preview folders are empty.
Also I notice that when I go to folders in Library and select all pictures then scroll down the list the thumbnails seem to be blurred at first and the 3 little white dots appear as if Lightroom is re-rendering the images.
I thought that once it did them the first time it would not do them again unless the image changed.
As a new user moving from Elements 4 I am trying to get a grasp of how Lightroom is organized so any info much appreciated.
OS is Windows with SP2.

"And, the previews are cached, but you'll still see the three dots for a moment as you scroll, but if they're cached they should all go away a whole screen at a time. "
This constant rendering of thumbnails and previews is the strangest thing about LR. I have a pretty fast computer running XP Pro SP2, 3ghz dual core with 4GB fast RAM, great video card, Matrox P650 128mb and fast SATA 10,000rpm hard drives, optimized in every way recommended by Adobe and it will not stop rendering thumbnails or previews. I render standard size previews (1680) upon import and render 1:1 previews after import.
I only have about 11k images in my library, mixed JPG and Canon RAW, and I simply cannot browse my images with anything like reasonable speed. LR is the slowest image viewer I have ever tried. Free stuff like Picasa is way faster and so is cheap stuff like ACDC. I mean way, way faster.
If I show LR a big group of pictures, say 2-3,000 images, it slowly renders the thumbnails as I scroll down screen by screen. The white dots appear for a whole screen, then disappear one by one, not a whole screen at a time. Finally, after the white dots disappear the thumbnail is sharp. If I scroll down say 5 screens of images, then reverse direction, the thumbnails re-render as I go back up the list of files! The 3 white dots reappear even though those thumbnails just rendered 15 seconds before! What in the world is going on? If I try to browse images in Fit or Fill or 1:1 size, the performance is even slower.
Since my computer flies through images, thumbnail and preview, with every other photo program I have tried, I have to think that LR is the problem.
