Can I delete lrdata files
I have a laptop that is almost four years old. It has a very small hard drive, and about 10Gb of the drive is occupied by lrdata files from my Lightroom catalogs. I only use this laptop for travel and run Lightroom to transfer images from my memory cards to two external drives where I store my images while traveling (the computer's hard drive being too small to store images). Because of this, the Lightroom catalog on the laptop is rather large, but I don't use it for anything. My desktop contains my master Lightroom catalog and files.
Can I safely delete the lrdata files from the laptop?
Yes you can remove it. It will not harm in any way as these are just the preview files.
If need any other help, please ask.
