Why the file size in the bottom corner of PS doesn't correspond to the file size on HDD?

My files are >2 times bigger!

Hi

It is like comparing apples and pears.

 

The file size on disk is the size of the file with aditional metadata and after any file compression is applied.

 

The file size at the bottom left is the size in RAM based on 3 x pixel width x pixel height for each layer (or 6 x pxlength x pxheight for each layer of a 16 bit document). However this itself can be under-reported as smart objects are counted as one layer at the document pixel size for that reported number. Whereas the actual content of the smart object can be a different pixel size, have several layers and even contain further nested smart objects.
