I could be wrong but I think the OP is after a solution for how to have individual file size info for each file displayed separately for insertion in a word doc.
Could an Automator Script do that or Terminal?
Or even a disc space analyzer app like WhatSize (free trial only) or GrandPerspective (free) might help?
What is "OP" ? I would like to copy/paste the FILE SIZES into a word doc or excel doc. I searched like crazy on the internet yesterday for a way to do it in automator and couldn't find anything. I kind of found a way to display that info using terminal, but then ran into a bigger issue!! the numbers that Terminal were showing were different then the numbers Finder was showing. Finder was saying the file size was 298.8 mb, while Terminal was saying it was 285 mb. Then I went into Final Cut Pro 7 and asked it to display sizes. And FCP agreed with Terminal on file sizes. So its like why are two separate applications telling me the file size is 285 when Finder shows it as 298.8? Very confusing and frustrating.
On another note though... the closest "solution" I've come across to get all the file sizes and names into an excel doc (without having to manually type them in), is bring all the raw footage into FCP, arrange by name, (select the columns you want, kind of), highlight all the clips on the left, go to file, and choose Export -> Batch List
