Not sure what you mean. There is a huge amount of vacant space to the right of the folder names and below the folders in left column. That image looks like the 'Attach File' window is super large in size. Are you talking about the window size or the content in the window? You would also need to post an image which shows that 'Attach File' window compared to another window. Suggest you open a new Write message and click on 'Attach' then put the two windows side by side, then open a window for a computer folder eg: Documents and take a screen shot of desktop. Then we have an idea of what you consider normal. It means we can compare all three in one image.
