Name

info for — file/folder information

Description

Gets information about an item on disk. Returns a file information record packed with useful stuff.

Example

set uf to (path to home folder as string)
set L to list folder uf
set s to {}
repeat with f in L -- collect sizes of all items
        set end of s to size of (info for file (uf & f))
end repeat
set maxItem to 0
set maxVal to 0
repeat with i from 1 to (count s) -- find biggest size
        if item i of s > maxVal then
                set maxItem to i
                set maxVal to item i of s
        end if
end repeat
display dialog ¬
        "The biggest thing in your home folder is " ¬
        & item maxItem of L

If you ask for the info for a folder, the script may take some time to run, in order to sum the sizes of all the files within it.
