SSD & HDD

And that last link reminds me of an odd bit that some members fail at. Where do you keep your backups, While that link talks of extra backup copies, I would recommend making sure that no backups are on the same drive as your working catalog, and for that matter not on your primary partition, nit on your C drive, if both working catalog and backup are on the same drive, then both can disappear when that drive fails. As for the primary partition, where your OS is, where all your programs are, just asking fir a hard drive failure on that one are we not. Lots of MAC OS users might not be aware that the OS backups by default are in the primary, just asking for it.

Ok, too many words, off subject, while cleaning up your drives think of that.

While I am thinking about it, from my collection of links, this one comes to mind for someone with hard drive space issues:

hmm, never occurred to me, I forgot to look for part 2, Here it is:

Do I assume correctly that your SSD is your. C drive where the OS resides, where the various programs reside?

If so, what other files, things like spreadsheets, word processing documents, other images, music, etc reside? can you free up significant space by moving them to the larger drive?

Also, and this will probably get some push back, Do you maintain/use just one catalog, how big is it, the catalog file? If you maintained multiple catalogs, and only kept the current photo call catalog on the SSD, would that free up enough space. mind you it is the images that take up the majority of space, and you have already mitigated that. And I have no idea what space savings may or may not occur.

There is something called a "symbolic link" that allows you to have previews on a different drive than the catalog itself; you can look up the details yourself. However, this may cause some slowness in LR, usually you want previews on your fastest disk.

As to not having it upload to One drive take it out of the One drive folder and or restrict one drive from uploading it.

The previews, smart or regular, are always stored in the same folder as the catalog file.

The only way to have the previews store on your 2 TB drive is to move the catalog to that drive and make LR use that catalog you moved/copied to that 2 TB drive.

The previews folders can NOT be moved by themselves.
