PHOTOSHOP: PSD file sizes are larger than I expect (history in metadata)

I've noticed my PSDs have been quite large of late, and decided to do a test.

I started progressively stripping away layers to see if it was a particular element, but it seemed to hover ~8-9MB.

So I stripped out all of the layers and re-saved with just a white color fill, and to be sure reduced the size to 1x1 pixels. The PSD then came in at 6.9mb..

I'm not saving any color profiles or layer comps etc with it, that I am aware of. Am I missing something really obvious? Or is this a bug? A link to the PSD is attached below for reference.

You recorded your document history in the XMP metadata - and now it has grown to just under 7 Meg.
If you don't want the document history bloating your files, turn off the history recording in Photoshop preferences.

Hi Chris,

My history log isn't on, and never has been. I didn't even know it was an option to tell you the truth.

Also of note, when I open the PSD, there are no history options available to me.

Well, you logged a lot of history to the metadata for that file. And the only way that would happen is if the history log was on.
Perhaps you had it on in the past, or another machine - since the history stays with the file (even if you duplicate the file).

Strange, I don't ever remember having it on.. Transferred to a blank canvas, and its about 7 meg lighter. Sorry for the confusion, thanks for your help!

You're not the first person to be surprised by the excess baggage of history recording. One guy had about 200 Meg of history, and he kept duplicating his files - so they were all oversized.

Yeah I tend to use common elements across a project, and I'd hate to imagine how many times this one had been reused! At least it was only 7mb each time haha. Thanks again!
