Size of “.Trashes” Folder on external Drive

Scripting Forums AppleScript | Mac OS X
#21

thanks again Yvan!

Sadly your new code gives me the old error

chmod: /private/var/vm/.Trashes: No such file or directory

I tried wrapping the repeat command in a try command, changed volName to item 4 again, my result:

{{“FF_ext_003”, -1.846161564E+9}}

#22

(1) When editing I misplaced the try/end try statements. It’s now corrected.

(2) To test I asked System Events to return the size of my Applications folder and got a negative value so I decided to use an other tool which is BridgePlus by Shane Stanley.
This one returns a more logical result: {totalFileSize:1.06473994557E+11, totalFileAllocatedSize:8.594223104E+10}

Here is the script using it.

(*
Download BridgePlus here: <http://www.macosxautomation.com/applescript/apps/BridgePlus.html>
Install BridgePlus.scptd in "/Library/Script Libraries/"
*)
use theLib : script "BridgePlus"
use scripting additions

tell application "System Events"
	set volNames to name of disks whose local volume is true
	--> {"SSD 500", "Macintosh HD"}
	
end tell
set theSizes to {}

set volName to item 1 of volNames

set POSIXPath2Trashes to POSIX path of (volName & ":.Trashes")
set quotedPOSIXPath2Trashes to quoted form of POSIXPath2Trashes
try # MOVED
	do shell script "chmod 775 " & quotedPOSIXPath2Trashes # Standard privileges
	
	set theSize to theLib's sizeInfoForFile:POSIXPath2Trashes
	
	set end of theSizes to {volName, totalFileSize of theSize}
	
	do shell script "chmod 333 " & quotedPOSIXPath2Trashes # Write Only privileges
end try # MOVED
set volNames to rest of volNames

repeat with volName in volNames
	set volName to contents of volName
	set POSIXPath2Trashes to POSIX path of (volName & ":.Trashes")
	set quotedPOSIXPath2Trashes to quoted form of POSIXPath2Trashes
	try # MOVED
		do shell script "chmod 775 " & quotedPOSIXPath2Trashes with administrator privileges # Standard privileges
		set theSize to (theLib's sizeInfoForFile:POSIXPath2Trashes)
		
		set end of theSizes to {volName, totalFileSize of theSize}
		
		do shell script "chmod 333 " & quotedPOSIXPath2Trashes with administrator privileges # Write Only privileges
	end try # MOVED
end repeat

theSizes
--> {{"SSD 500", 0}, {"Macintosh HD", 6.08037518E+8}}
