The default location of the Lightroom catalog is…
Windows Vista or 7—C: \ Users \ [your username] \ My Pictures \ Lightroom \ Lightroom 4 Catalog.lrcat
Mac—Macintosh HD / Users / [your username] / Pictures / Lightroom / Lightroom 4 Catalog.lrcat
The catalogs are fully cross platform, and the catalog file extensions are:
*.lrcat is version 1.1 onwards.
*.lrdb was version 1.0.
*.aglib was the early beta.
The default location of the Preferences is…
Windows Vista or 7—C: \ Users \ [your username] \ AppData \ Roaming \ Adobe \ Lightroom \ Preferences \ Lightroom 4 Preferences.agprefs
Mac—Macintosh HD / Users / [your username] / Library / Preferences / com.adobe.Lightroom4.plist
Preference files aren’t cross-platform. By default, Preferences are a hidden file on Windows and Mac OS X.
The default location of the Presets is…
Windows Vista or 7—C: \ Users \ [your username] \ AppData \ Roaming \ Adobe \ Lightroom \
Mac—Macintosh HD / Users / [your username] / Library / Application Support / Adobe / Lightroom /
Each type of preset has its own folder, for example Develop Presets, Filename Templates and Metadata Presets. Presets are cross-platform and are saved in a Lightroom-only format (.lrtemplate).
If you’ve checked the Store presets with catalog checkbox in Preferences, they’ll be stored next to your catalog file instead.
To find them easily on either platform, go to Preferences > Presets tab and press the Show Lightroom Presets Folder button.
Your Develop Defaults, Lens Defaults and Custom Point Curves are stored at…
Windows Vista or 7—C: \ Users \ [your username] \ AppData \ Roaming \ Adobe \ CameraRaw \
Mac—Macintosh HD / Users / [your username] / Library / Application Support / Adobe / CameraRaw /
Your Develop default settings, lens defaults and custom point curves are shared with ACR, so they’re stored in the shared location, regardless of your ‘Store presets with catalog’ setting.
The default location of the Camera Raw Cache is…
Windows Vista or 7—C: \ Users \ [your username] \ AppData \ Local \ Adobe \ CameraRaw \ Cache \
Mac—Macintosh HD / Users / [your username] / Library / Caches / Adobe Camera Raw /
Your custom Camera Raw & Lens Profiles should be installed to the User folders…
Lightroom 4 no longer uses the shared ProgramData (Windows) / Application Support (Mac) folders for Camera or Lens Profiles. Instead, it stores the built-in profiles with its program files.
When you create camera or lens profiles, they must be stored in the user locations listed below. If you previously stored custom profiles in other locations, you’ll need to move them to these user folders, otherwise Lightroom won’t be able to find them.
Windows Vista or 7—C: \ Users \ [your username] \ AppData \ Roaming \ Adobe \ CameraRaw \ CameraProfiles \
Mac—Macintosh HD / Users / [your username] / Library / Application Support / Adobe / CameraRaw / CameraProfiles /
For the lens profiles, substitute the LensProfiles folder for the CameraProfiles folder.
The camera and lens profile file extensions are:
.dcpr—camera profile recipe file used for creating/editing a profile in the DNG Profile Editor
.dcp—camera profile
.lcp—lens profile
in what category are LR brushes located? trying to move my Presets and Brushes from one computer to my new one. thanks!
They’d be under “The default location of the Presets is…”
after searching through your other articles… I just want to go bang my head against a wall. That’s what I get for trying to do things like this on little sleep. I just go and miss the obvious. UGH! So sorry.
I’ve copied followed the pathway to my old computer’s Preset location and copied the files and tried to copy and paste them into the exact same file location on my new computer, but it won’t “link them up”… am I doing something wrong? I was able to get my catalog transferred and connected correctly on my new computer but it “connected” by clicking on the new catalog folder and it opened up Lightroom with my “old” catalog (correctly as I was wanting it to do). Not sure what I might be doing wrong in this situation. It doesn’t open Lightroom by clicking on the folders, as it did in loading my previous catalog onto my new computer’s Lightroom. Thanks for any help you might could offer!
What do you mean it won’t “link them up”? I’m afraid I’m not following your question! Take me step by step through what you’re doing, what you’re expecting to happen, and what’s actually happening. (Or better still, post it on the forum at http://www.lightroomforums.net as it’s easier to troubleshoot in that conversation format)
Will try the forum. thanks!
