What is a .LRPREVIEW file?
The file extension .LRPREVIEW is associated with Adobe Lightroom, a software program used for organizing and editing digital photographs. This type of file contains a preview image of a photo that is stored within Adobe Lightroom. Essentially, it's a smaller version of the original photo, which helps in quickly viewing and managing large collections of images without loading the full-sized originals every time.
These .LRPREVIEW files are part of Lightroom's catalog system, where they are stored in an image cache. If for some reason the original high-resolution images are lost, these preview files can be very useful. With the help of a special plugin called "Extract Cached Images," users can convert these preview files back into standard .JPG files. This can be a lifesaver for recovering lost images at the same resolution as the originals, provided that a 1:1 preview was created in Lightroom.
However, it's important to note that the "Extract Cached Images" plugin only works with Adobe Lightroom versions 2 and 4. As for opening these files, the primary software is Adobe Lightroom. Additionally, there was a program called LRViewer which could also open and handle .LRPREVIEW files, but it has been discontinued. LRViewer allowed users to directly view these previews and export them as .JPG files.
In summary, .LRPREVIEW files are useful for managing and recovering image previews in Adobe Lightroom, especially when the original files are no longer available. They can be opened and processed back into full-resolution images using specific versions of Adobe Lightroom with the appropriate plugin.
