Question

What's the biggest .tiff size fill that Version 10 can manage, since Version 9 does'nt like anything over 27.MB

Answer 1

MTSTUNER,
I remember us talking about Adobe documenting the maximum file sizes, and I just found this while browsing on the Photoshop Developer's site (http://www.adobe.com/devnet-apps/photoshop/fileformatashtml/).  It's a description of the PSD file header information:
File Header Section 
The file header contains the basic properties of the image.
Length
Description
4
Signature: always equal to '8BPS' . Do not try to read the file if the signature does not match this value.
2
Version: always equal to 1. Do not try to read the file if the version does not match this value. (**PSB** version is 2.)
6
Reserved: must be zero.
2
The number of channels in the image, including any alpha channels. Supported range is 1 to 56.
4
The height of the image in pixels. Supported range is 1 to 30,000.
(**PSB** max of 300,000.)
4
The width of the image in pixels. Supported range is 1 to 30,000.
(*PSB** max of 300,000)
2
Depth: the number of bits per channel. Supported values are 1, 8, 16 and 32.
2
The color mode of the file. Supported values are: Bitmap = 0; Grayscale = 1; Indexed = 2; RGB = 3; CMYK = 4; Multichannel = 7; Duotone = 8; Lab = 9.
So it's not surprising that PSE's max is 30K x 30K.
