Purge, Resize or change ACR cache in Elements

" 1. In Adobe Bridge, choose Edit > Camera Raw Preferences (Windows) or Bridge > Camera Raw Preferences (Mac OS), or, with the Camera Raw dialog box open, click the Open Preferences Dialog button .
2. Do any of the following:
To change the cache size, enter a Maximum Size value.
To purge the camera raw cache, click the Purge Cache button.
To change the location of the camera raw cache, click Select Location."
This is from the help for CS3.
When I open the preferences for ACR in PSE6 there is no button to Purge the Cache, resize the cache or change its location.
How can I make any of these changes for ACR in PSE6?

Thank you Thomas , however
Why then does the ACR cache fill up when running Elements; mine is at its 1GB limit. If it is not being used should it not be empty?

Can't change ACR cache location or size

Whenever I go to change the location of the cache, or even its size, the value immediately resets back the next time I open the preferences panel. Same happens if I try to do this in ACR 6.1. The location that I want to point it at is perfectly valid, on my local drive, and I have all permissions for it.
Since Adobe apps are slightly retarded and don't follow symlinks, an attempt to sneak in a different location under a symlink ended up as expected in a crash.
Any ideas how to change the ACR cache path, or why it would be failing? No messages in the Console. OSX 10.6.4, Nehalem MacPro.

No, links don't really work with any Adobe apps, at least not on OSX. Just try to create a symlink to any of the Camera Raw settings folders (lens profiles, camera profiles - so that they are all the same on all my computers) - no dice. I write OSX software for a living and know my way with symlinks - not sure what Adobe is doing but they don't work.
But that's not the issue here - my question is why I can't change the cache directory the "normal, pedestrian way" (your average user won't know anything about symlinks).

Found a significant LR4 speedup - regenerate ACR cache

Like many others here, after I upgraded to LR4, my performance went completely to hell. It would literally take 9-10 seconds just to advance to the next image in the Develop module. Marking an image for deletion would take 15 seconds. I'm running a Q6600 - quadcore processor at 2.4GHz with 4GB RAM on Vista 32-bit. By today's standards, it's not a terrific speed demon, but no slouch either and it worked fine for several years with LR3. I mostly process D300 RAW files.
After reading a lot of posts here about crummy performance, I wasn't able to find any tips that might help so I started poking around in the preferences/settings. One thing I discovered was that my ACR cache was perhaps getting starved a bit for size. It was set to 50GB, but it was on a drive that might not have that much free space. I reasoned that if the cache couldn't quite be large enough to hold my working directory of images, then it might be thrashing and pretty much never loading from the cache.
So, I moved my ACR cache to a new drive with lots of free space, increased the cache size to 100GB and then proceeded to regenerate the cache for the directory of 500 images I was working on by making a 2 point change in sharpening on all images and then regenerating all previews. It took awhile to make all new previews for all the images, but after doing so - WOW my old performance was back again, even running on the new 2012 process. I could move from one image to the next in the develop module in under a second.
So, I don't know if it was low disk space, some sort of general caching problem, a corrupted cache or what, but after making those ACR cache changes, my LR4 performance is back neaer where the LR3 performance was.

I have significant problems with near lock up in LR4 and have posted a discussion (it takes HOURS to import a couple hundred photos, minutes to load a photo just to view sometimes). There have been no suggestions in reply to my original post -so maybe I can tag along here for some assistance? Please? In LR, I opened the preferences (in Edit) and found that my Camera Raw Cache Settings were set at 1. GB maximum size, with the Video Cache set at 3.0 GB. Hate to be dense, but I want to be sure I am not causing with more problems.....so, I should purge cache on each first, then change maximum size to 100? Since mine is set on 1. that seems pretty drastic, since my system says it has 308 GB free out of 465.
I have an HP server which I can can use (instead of the default C drive which it is set to). My system is less than 2 years old, Windows 7- my processor is AMD Phenon(tm) II x 4 925 Processor. My hard drive back up has plenty of space - 4 terabytes. Could Purge Cache and change these settings in any way cause another problem? Should I change this to my hard drive -if so, would I use the same file location, except change to my server?
I have a Mac with the same cache settings, and it is lightening fast with LR3 compared to this. I really don't know how to ask the right questions -my knowlege about computer systems, etc. is limited.
One of my symptoms before fixing my cache was that importing was ridiculously slow (hours to import a few hundred images) so my experience does overlap with your symptoms. How big a cache you need depends upon what you're processing and how many you work on at a time. I presume the ACR cache (which is what I wrote about here) is mostly (or perhaps only) used for RAW images so it's most applicable if you shoot RAW. Secondly, you need to think about your working set of images (how many you work on at a time). What you want is a cache that is big enough to hold cached versions of every image in the set you work on. That way, you can import the images into LR which will build previews and fill the cache in the process and then you can go back and work on your images and they will all be precached. If your cache size is a little smaller that the working set, then by the time it gets to the end of building previews, the cache is full and it's kicking your first images out of the cache. Then, you go to start working on the first images and there's nothing cached so it keeps having to back to the RAW file for every new image. This is when it's going to be really slow. OTOH, if your cache is larger than your working set, then all images you are working on in a particular shoot can stay in the cache for the duration of working on them.
I think the norm for the ACR cache is around 50GB just to make sure it's big enough for a large shoot. 1GB is miniscule and won't be doing you much good at all.

ACR Cache

I own CS3.
My digital processing PC has 3 drives.
My C: drive has just programs and OS. It is a 36 GB WD Raptor
My D: drive is a slower WD Caviar 320GB and houses my RAWs and processed jpgs. I use other 320GB Caviar drive (my E: drive) as one of my backups (should D: fail).
The other day I noticed, to my surprise, that my C: drive had less than 1 GB of free space remaining. Hmm, that's interesting, I didn't have THAT many programed installed. I looked to see how this was possible and noticed that there is a huge amount of space (>6 GB) in the user "Documents and Settings" folder devoted to both Camera Raw and Bridge cache in various 'Application Data" folders. I prefer to have more free space on my primary C: drive. I noticed Picasa was storing a ton of files on it as well as freed a few GBs of space by only allowing Picasa to view JPEGs (and not my RAWs). So i wonder if there is some maintenance/preference changes I can do with CS3 to further create drive space. The E: drive is only used whenever I backup files.
In ACR Preferences I noticed I could change where Camera Raw's cache is stored. Should I change it to my rarely used, but slower, E: drive or just decrease the size of the cache? Can I do so for the Bridge cache as well? And if I do change the cache's location, will all of the information currently store in the cache's present location be migrated to the new location automatically?
Any advice is appreciated. I prefer to be taking photos rather than trying to figure out how my computer works.

Thanks - I'd long ago assigned the PS scratch drive to my internal E: drive. I guess my biggest question is if I reassign the drive for both my Bridge and ACR caches to this drive, will the contents of the cache migrate to the new drive seamlessly? I guess this is technically a Windoze inquiry.
I just want to avoid any problems like finding out the many GBs of cache info was not transferred to the relocated folder and no longer accessed by PS/ACR due to the fact the cache folders are in a new location.
Jao, I just assumed the 320 GB drive would be slower as it is not a Raptor 10,000 RPM drive like the boot C: drive. But maybe it IS faster if the system is forever accessing thngs of the system drive. Don't know - my passion is photos, not information processing.
Thanks for all the help thus far guys!!

How to - move ACR cache and LR cache and catalog

Hi all,
in the try of speeding things up a bit with my LR (v. 2.4 64 bit on Vista 64 SP2, E8650 proc and 8 GB RAM) I got an 2nd hand WD Raptor 150 GB 10K rpm, and I'd like to move there the ACR cache (around 60GB now) and the LR previews and catalogs (around 20 GB) . Which is the right and safer procedure to do that!? :-)
Another question: my setting about File Handling are the following:
1680 pixels as standards preview file size
Preview quality Medium
Never discard 1:1 preview size
and in the grid mode (library) when I page down or up ... I always have the 3 white dots (of waiting) the pictures taken 3-4 secs go from fuzzy to sharp. How can I improve that time?
Thanks to all who will answer :-)
Have a nice day,
gianluca

There is nothing you can do to change the time that thumbnails to refresh. The fuzziness is normal while the three dots are visible and indicates that Lr is scanning the files within the Grid for external metadata or develop changes.
To move the catalog and preview folder you simply drag (copy) it to the new drive, open the relocated folder and double click on the .lrcat (catalog) file. The double click operation will open Lightroom with the relocated catalog active.
You can drag the ACR cache file to the new drive. However, to ensure Lightroom/Camera Raw use the correct ACR cache you will need to open Preferences>File Handling and point to the location that you want the cache files to be saved.
Be aware that moving above folder is going to take a fair amount of time, albeit significantly less than rebuilding the cache and previews from scratch.

Need changes in standard data element

Hi gurus,
I want to change in one of SAP standard data element for adding search help into it.
for this fields there is no user exit or any enhancement is present.
I have taken access key from our basis guy after putting access key i am unable to change the data element i mean access key is correct but i am unable to edit data element.
so can anybody tell me how can i change in this data element.
note : I have access key.

Hi,
What data element you are about to change, you should take extra care before changing standard data elements as it may be used in many places.
Do a Where-Used list to determine nothing else will be affected because of this change.

You need to force quit all other (real or fake) instances of the Application Manager. Instructions differ between Mac or Win.
A lot more information about your hardware and software is needed.

How can i change the order of elements in a JList ?

Hi,
i would like to know if it is possible to change the order of elements in a JList ? Maybe i could use drag and drop to do this ?
Thanks for answering.

The simplest way is probably to implement ur own listmodel and then supply the listitems in the order u want. Example:
class MyListModel
          extends AbstractListModel
          implements ContactListListener {
public int getSize() {
return listitemcount;
public Object getElementAt(int index) {
//here u return the item for the index at the list
//if u for example have an array of strings
//which u wanna have listed in reversed order (reversed to
//the order in the array, u could do
     return myarray[getSize()-index];
}

Trying to change the cache size of FF3.6 from 75meg to a larger size, it only applies on a per session basis. i check the about:config and the changes have applied but when i restart FF it has reset itself to 75 :(

as per the question, tried to up the cache from 75meg to 300meg but it resets after i restart firefox, have tried to change to various cache sizes but to no avail.
-=EDIT=-
it must be something to do with the profile, as when i set up a new profile in the manager, the cache size problem no longer appears. but now, how to repair my profile

ok, nothing in that text file helped but the original file that it was based on pointed me in the direction that it might be an extension. The only extensions i have are NoScript and FasterFox Lite version....
I have now traced the fault to lie with FasterFox... if you are not familiar with fasterfox it speeds up internet connections in firefox... several of the options are presets... but when i selected custom it gave me the option of a cache setting, which was set to 75megs.
I have now changed that cache setting in fasterfox to 300 Megs and it is now persistant in firefox on restart.
hopefully this information will be helpful to other people in the future that suffer the same problem.
Thanks for your help TonyE, its greatly appreciated

How do I Change the Cache size?

I have an iBook G4 and am trying to change the cache size for this screen saver I downloaded.
iBook G4 Mac OS X (10.4.9)

Hi
Curious which screensaver you are referring to?
Screensavers can be processor intensive, requiring a certain level of computing power to avoid flicker or stuttering. The G4 iBook is not that type of machine.
Some Screen Savers have a preference file (accessed through the Desktop and Screen Saver System Pref Panel - highlight the saver, and select "options" if one is available) where you can adjust the operating speeds and other parameters. Otherwise, I don't believe there is anything more you can do.
I notice a big difference in certain screen savers running on my G5 iMac vs. my iBook, with the former handling the screen movement much more easily.

Change Appearance Color in Elements 6

Hi,
New to Elements 6 and what a surprise. My eyes can't get used to working with a black background. I'm told there is a slider somewhere that will change the appearance of Elements 6 from Black to Gray in both the editor and organizer similar to Elements 5. Would someone please tell me how to access them?
Thanks,
John

I just upgraded to Elements v7 from v4. I HATE the balck background. Is there any way to change it to a lighter background? Dear ADOBE, why would any company purposely make its product hard to read and more difficult to operate by making the background black? Besides, over 95% of all photo uses (webpages, printed documents, newsletters, etc) are printed on white or ligher colored backgrounds. Why wouldn't you allow us to work with an image in an envornment it is goign to be used? Ever hear of testing the product with focus groups of users. I can't remotely image that users prefer the black background. Idiots!

Locking and non-persistent changes in cache

I have a question regarding Optimistic locking and modifying objects in the cache.
I have a case where one client modifies a (persistent) object, but since it is a temporary change, which should not be persisted, it is not within a UOW. However, when the next client reads the same object, it gets the modified value and not the original value, which is not correct.
For the moment, there are no locking defined for the descriptors, but would Optimistic locking help in this case? Does this not only protect when you try to write a change on a stale object to the database?
If you run the risk that someone might change an object, and consequently change the cache and how the object is seen by others, should the reads be performed in a UOW?
Regards,
Katarina

Yes, if you may make changes to the object you must make the changes in the unit of work, even if you do not intend to commit the changes. Reads from the session are strictly read-only.

When resizing a picture in photo shop elements ?

When resizing a picture in photo shop elements 7,
can somebody explain the difference between bi-cubic and bi-cubic smoother?

Hello,
The way I understand it is this:
When you resize an image for sending to someone or viewing on the web or a monitor the size should be 640x480 pixels. You are actually making your image smaller and Adobe recommends using 'bicubic sharper'.
When you resize an image for printing you want to check your ppi or pixels per inch. Ideally it should be 300ppi with 200ppi being the lowest density for an acceptable print. A point to remember is that Canon cameras usually come in at 180ppi so check your camera and set it for the highest quality in the camera menu. Adobe recommends choosing 'bicubic smoother'.
The choice is actually yours to make in either case. If you don't like what you see choose one of the other resampling choices to get what you want.

ACR Cache - Is It Broken?

There's been some discussion in another thread about this, but its really off-topic there, and I think warrants its own thread...
I can find no value in the ACR cache whatsoever. Begging the questions:
- Is it working as it should, and there is some subtle value I'm missing?, or
- Is it broken??
At the moment, I'm totally perplexed.
When switching views in develop mode to one which DOES HAVE a 1:1 preview available, but DOES NOT HAVE a complete raw-rendering available due to a recent rendering (presumably in RAM, although I dont know), the sequence of display phases for me is:
1. Nice
2. Bad
3. Nice
And the sequence is not noticably faster with a cache entry available - I haven't done rigorous checking.
Nor are the views any nicer when cached.
Nice #1 I assume is the lib preview (which comes up in less than a second and lasts for about a second)
#2 (Bad) I assume is the develop module's first whack at a rendering (and generally lasts about 2 seconds).
NIce #3 is the final raw rendering (loading indicator is extinquished when this view is presented).

...my Win7/64 system shows all three phases when there is a disk cache and the second phase blurriness is somewhere between the first image that appears and the final images that appears. When I do this exercise at 2x or 4x it look more like a low resolution preview is being inserted at phase 2 rather than a blurring. On my 30" screen, low resolution images appear blurry when blow up. See if you agree with this observation.
Doesn't sound like what I'm seeing - hang on and I'll post 3 screen-shots. In the mean time, add a gradient @100% across the whole image at sharpness=-55 and you'll see what I'm seeing in phase 2 (presumably).

I don't know if it really matters where this intermediate image comes from or why it is displayed. I simply have learned to not panic when I look up and see a "not so sharp" image in develop module.
With my last motherboard it took ~15 seconds for a develop mode view - I've been so happy with the improvement that I hadnt been scrutinizing performance. In fact, it was trying to answer other peoples questions that got me looking at it more closely. My phase 2 is very blurry - its worse than "not so sharp" - I'll show ya in a minute.

Whoa - 30 seconds for a batch of dust spots - yhouch! - I've seen Lightroom go wonky when adding / updating dust spots a few times (and take forever + not responding...), but usually works OK for me...
