When you archive raw files to a CD or DVD, if you are using a centralized cache, instead of distributed, the cache you created for thumbnails and previews when you first viewed the files will not be copied to the CD. This fact results in the cache's having to be created all over again when you view the files from the CD. Likewise, if you have elected not to save the XMP metadata generated by Camera Raw as sidecar files, it, too, has to be regenerated. It all adds up to slower previews from CDs.
Consider taking the following steps to ensure speedier previews:
1. Choose Preferences ^ Advanced ^ Use Distributed Cache Files When Possible. This will put the caches in the folders that you are viewing, making it easier to transfer them to the CD or DVD. However, it will also put caches in every folder you view, including your desktop. That's something to be aware of before you select this option.
2. If you prefer to use a centralized cache, possibly for the preceding reason, choose Tools ^ Cache ^ Export Cache; doing so creates a copy of the cache in the current folder, which you can copy to the CD or DVD.
3. Elect to save XMP metadata as sidecar files in the Camera Raw Preferences dialog box so that they always travel with the raw files that they are describing. If you have elected to store Camera Raw settings in a central database because you prefer not to see sidecar files in your folders, select the raw files (maximum is 24 at a time), open them in Camera Raw, and then choose Export Settings from the Camera Raw menu. That will export the settings, which you can then copy with the raw files.
Finally, when you burn the CD, make sure that Adobe Bridge Cache.bct, Adobe Bridge Cache.bc, and sidecar (.xmp) files are all present in the same relationship to the files as on the hard disk. The sidecar and cache files are not visible by default. To see them, choose View ^ Show Hidden Files.
