Short version: I want the ability to move smart previews and the cache location to another disk.
Long version: I have limited space on my C drive. I want the ability to save SmartPreviews and also the cache to another disk. I have a additional capacity on a scratch SSD and also HDD for which I would prefer to use for the caching functions. This would allow me to give Lr a lot more space, which would be useful when searching/viewing my 600GB picture database.
This issue will likely hit multiple people over time, as anecdotally more people are upgrading computers instead of replacing with the current elevated costs of computer equipment (and computer prices do NOT seem to be coming down). Note: this is caused by the rather painful process to replace a Windows C drive.
