    What is the role of the folder 'Lightroom 5 Catalog Previews.Irdata - Can I delete it?  It is a memory hog.  There is a separate Lightroom Catalog 5 folder.


      My SSD hard drive has limited space which I use for programs and store pictures files on various external HD.  I ran into a space wall on the SSD C drive, and noted the above file is about 13.2GB for 20k picture previews being held.  Can I delete this file?  What is the impact on LR?
