There is a limit to the amount of images that are stored in the central cache. If you imported more than this limit the eldest and less viewed files will be replaced by the newest files in the central cache.
Strange you don't like the option of sidecar xmp. With this option there are just tiny little files traveling along with the originals, it is really a good way of handling a large amount of files
the xmps double the amount of files in each folder, its an enourmous amount of clutter for someone who sorts their photos in windows explorer. is there no way to have camera raw create these sidecar files but save them to a centralized location/folder? this software sure has a lot of silly limitations.
so the cache is where the raw settings are saved? i thought this is where thumbnails and that kind of thing was saved?

There are TWO caches. The Bridge cache and the Camera Raw cache. You need to purge the Bridge cache. You need to the Bridge menue to do that, not the use button in the Camera Raw preferences dialog, which purge the Camera Raw cache, which is not the problem.

Purging the cache does not lose any edits in CS2 when working with raw files.
..i don't want to purge anything, i want to backup my edits when i back up all my raw (.cr2) files.
That has nothing to do with the aforementioned caches.
Ok guys lets start over, we have a dozen replies and no actual answers. What folder or files do I need to backup if i want to save my raw image options/edits/changes if I'm using the database method and not the xmp sidecar method?
In Windows, it's at:<br /><br />C:\Documents and Settings\<username>\Application Data\Adobe\CameraRaw<br /><br />and the filename is Database (no extension)<br /><br />This is a hidden directory, you'll need to set Windows to display Hidden <br />Files and Folders.
and what good backing up the database by itself will do you is another question.
the same thing as backing up the xmp files, saving your image settings?
In case of data loss, how would you propose to get the information from your saved database to your images if you only save the database?
Ramon, the OP's original question was: "when backing up my raw files,
besides the image files, what do I need to backup to ensure that it also
backs up my settings?"
And he did get answers, he only does not want to hear them :-)
If you are able to set xmp to sidecar files you must be in Bridge. And I admit I am a Mac User with little to less experience with Windows but why use Explorer if you have a great application like Bridge to work with, being able to sort, rate and rename in multiple ways??
You miss the point. I was referring to the reply to my post, not the OP.
Ramon, I may be missing your point, but I still think that the original
question was: if I use the ACR database, instead of sidecar files, what
file do I need to backup along with the image files?
I've tested this already, by using the database, then modifying a few
files. I copy the database file to a safe location, and pretend it's
damaged by deleting it from the original location.
Sure enough, restarting Bridge shows the changes are now "lost".
I then "restored" the database file, and the changes reappeared.
Seems like a viable backup solution to me. Backup the image files and the
database files. Restore same if there is data loss / corruption.
For the last time, Klaas: my remark referenced the response to my post specifically. It had nothing to do with the original post.
Sorry, now I understand - your post specifically said:
"and what good backing up the database by itself will do you is another
even though the OP isn't intending to backup the database by itself, and
never said he was going to do that.
"the same thing as backing up the xmp files, saving your image settings?"
probably assumed that you knew from his original post that he wasn't
intending to backup the database by itself.
I apologise for misinterpreting your pendantry.
What a waste of time.
So, let's say you were to move gigs upon gigs of .CR2 files from one computer to the next. While you were doing that, you did some house cleaning and organized all your folders by year, by catagory. Then all of the sudden, you realized all of your ACR settings were not there anymore. Could I go back to the old computer, copy the contents of <br /><br />C:\Documents and Settings\<username>\Application Data\Adobe\CameraRaw<br /><br />and restore in the new computer? The problem I have, is that all of my paths have changed.
The camera raw database is indexed by file contents, not file paths, so just moving the database over works fine when moving between machines.
XMP sidecars are really a better solution for multiple computer workflows, however.
Thank you. They kind of bug me, but now knowing what I know...... It may be better to work with them. Thanks again.
