get size of items in finder

Scripting Forums AppleScript | Mac OS X

#1

If I do:

try
tell application “Finder” to set thisList to items of folder xxx
on error
set thisList to {}
end try
repeat with i in thisLisT
log size of i
end repeat

I get “missing value”, if I start this script a second time, I get no “missing values”, but if I restart the mac I get again “missing values”

#2 
tell application "Finder" to size of i
log result

Or, if you’re dealing only with files:

log size of (info for (i as alias))
#3

thanks, it works, but it is really slow, to slow for my application

set myPath to “Applications”
set a to “”
try
tell application “Finder” to set backupFolders to items of folder myPath
on error
set backupFolders to {}
end try

repeat with i in backupFolders
set a to a & return & name of i & tab & size of (info for (i as alias))
end repeat
display dialog a as string

Then, you may use the shell, something similar to this:

do shell script "find ~/Documents -type f -ls -maxdepth 1 | awk '{print $11, $12, $13, $7}'"

Take a look to “man find” or “man ls” (or “man wc”) in the Terminal.

thank you, I tried:

set x to name of i & " " & word 1 of (do shell script "du -k -d 0 " & POSIX path of (fromPath & “:” & name of i))

in the repeat loop, but if I selected the applications folder, it takes about 20 sec to take all information.

I want to to a list with name and size of all items of a folder like documents, home, applications, … It should be pretty fast to get all infomartion (name and size) of the folder. I need this to desplaye the items (with size) in my application. With your script I get only files, but no folders.

Yeah, I was getting a similiar problem: sometimes ‘size’ reports missing value for no appearent reason. Note: ‘physical size’ presented no problems.

In any case, this is pretty useful:


set f to choose folder --> for debugging

tell application "Finder" to get {name, size} of every item of entire contents of f

What you get back is a list of 2 lists, the first list contains item names, while the second contains their corrosponding sizes. You can also just get folder info, if that’s what you’re primarily interested in:


set f to choose folder --> for debugging

tell application "Finder" to get {name, size} of every folder of entire contents of f
--
--	{	{ "My Folder 1", "My Folder 2", etc...},
--		{  3.2249654E+7,        8053.0, etc...}
--	}

thank you
I’m interested in name and size of every item (files, folders, app) in a folder to add them in a table view.
I did:
set myPath to (“Users:” & (do shell script “echo $USER”))
tell application “Finder” to get {name, size} of every item of folder myPath
set thisItems to result
set nameI to item 1 of thisItems
set sizeI to item 2 of thisItems
repeat with i from 1 to length of nameI
set a to a & return & item i of nameI & " " & item i of sizeI
end repeat
display dialog a as string

but i get always “missing values”, until I did it again

Yeah, this definately seems like a bug. The problem doesn’t
seem to occur with ‘physical size’, can you use that instead?


tell application "Finder" to get {name, physical size} of every item of folder myPath
#9

I get “missing values” if I use “physical size” or “size”

#10

Wow, this is a serious bug:


tell application "Finder"

	get size of (choose folder)

end tell

I seem to randomly get either ‘missing value’, 0.0, or the
actual value I want, especially with the “special” folders of
the OS, like Applications, Users, etc.

I was going to recommend using the ‘info for’ osax command:


get size of (info for (choose folder))

but this turned out to be extremely slow for large folders like
“Applications”. ‘infor for’ seems to calculate a size rather than
have it readily at hand as the Finder’s ‘size’ property does.

#11

try this, it works (not very fast, but ok), it never shows “missing value” or 0.0!!!

set fromPath to “Users:” & (do shell script “echo $USER” & “:Desktop”)
set a to “”
try
tell application “Finder” to set the sourceFolder to folder fromPath as alias
set the itemList to list folder sourceFolder without invisibles
on error
set itemList to {}
end try
repeat with i from 1 to count of itemList
set currentInfo to info for (((sourceFolder as string) & item i of itemList) as alias)
set the currentName to the name of currentInfo
set currentSize to (size of currentInfo)
set a to a & return & currentName & tab & currentSize
end repeat
