Photoshop: File size & saving as PSD issue

I have a composite I'm working on. In PS 20.0.1, the Doc size is listed as 69.9M/578.2M. In Bridge it's listed as 137M. In Finder it's showing as 144M. Why then is PS telling me it can't save the file as a PSD file because it's over the 2GB limit? I've worked with lots of files that exceed the 2GB limit and I know approximately how the program behaves when file sizes get that big, and the indicator usually indicates somewhere near 2 GB, but in this case, there is nothing anywhere that indicates this file is even close to 2GB, except now PS is telling me it can't save it as a PSD file, meaning I'll have to save it as a PSB file. I'd really like to know why this is the case because I don't really want to work on this as a PSB file.

Could you save the file as a PSB and share it so we can investigate?

Hi Jeffrey, as I mentioned elsewhere (see below), this file is no longer in a psb format. My real question is why PS, Bridge, Finder were all showing the file size as being less than a gig, yet the actual size turned out to be around 7 gigs? Are shape/vector layers not counted in the sizing? Interestingly, even before I flattened the huge number of shape layers and merged them, the file size was still coming in around 7 Gig's (as shown in Bridge) yet PS never showed the file as being larger than 575 MB. That is the part that's confusing me, but I'm not sure now it's an actual bug. This is the first time I've worked with a large number of shape layers so I may be getting tripped up there. If I do run into this again, I will share the psb file (can you share a 7 gig file?) though. Below is the explanation on how this evolved I posted in the thread regarding not being able to skew or distort a layer, which applies here too, I suspect. I suspect at this point there is nothing further that can be done on this. Thanks again for your help:

Hi Glenn, hard to say without examining a specific file. When a file is open in Photoshop, the files sizes are estimates and change based on the file format and parameters selected (whether layers are included, image pyramids, compression, etc).

Lots of things can contribute to increasing the file size unexpectedly (image size or crop using inches instead of pixels).

I understand. This isn't a huge deal for me as I work in .psb formats much of the time anyway, but I couldn't figure out why it "blew up" on me as it did. Overall though, it doesn't matter that much to me so I won't worry too much at this point. Appreciate you telling me how it can be affected though. That does help. Thanks for your help.

Sure. If you do encounter a file you want me to look at, let me know. I can make arrangements to CC Files or Dropbox it to me.
