Info on PSBs from Help:

"Large Document Format (PSB)

"The Large Document Format (PSB) supports documents up to 300,000 pixels in any dimension. All Photoshop features, such as layers, effects, and filters, are supported. (With documents larger than 30,000 pixels in width or height, some plug-in filters are unavailable.) You can save HDR, 32-bits-per-channel images as PSB files."

Whaat version of PS do you have and what is your OS?

For info, one of the objections to psb in the past was that Lightroom couldn't handle PSB files. However, since the last release, it can and psb files appear in the Lightroom catalogue just like PSD.

So PSB is basically Windows 10 exFAT and PSD is Windows XP with FAT32 (in a way)? Also, how does PSD interact w/ Lightroom when they are both opened? I don't understand how the PSD modifications link to Lightroom???

Nothing to do with the FAT, which is the way the file is stored on a disk.

PSD and PSB differ in the the way the file itself is constructed. PSD has a 2GB filesize limit and a pixel dimension limit of 30,000 x 30,000. PSB has a filesize limit of 4 Exabytes and a pixel limit of 300,000 x 300,000.

Lightroom catalogues various types of file and can read the additional flattened image that is stored inside a PSD file when "Maximise Compatibilty" is checked in Photoshop preferences. Until recently, Lightroom could not read the same for PSB files, but that was fixed and the current version can now read psb files (albeit with a limit of 60,000 pixels on either height or width which is the maximum for Lightroom).

Yes, PSB. It's in the dropdown list of files. It's for large files over 2 GB.

Use PSB instead of PSD that files format has no size limit.
