Just a newbie surprise.
I have tried an elementary script to delete temp files.
It goes like this:
---
tell application "Finder"
try
delete file "tempA" of desktop
delete file "tempB" of desktop
delete file "tempC" of desktop
end try
end tell
---
-->
tempA is deleted
tempB & tempC are not

No answer but I'd add an "on error" to the try loop or remove the
"try" altogether. I'll bet Finder thinks it has some error that
you're not seeing.
Bingo !
If I remove the "try", it works fine.
2 subsidiary questions:
- 1 Why is this "try" a problem ?
- 2 If I remove the "try", I am going to get an error message when
one of the 3 temp files is not found. How can I avoid it ? "On error "
? If yes, would be the syntax ?
1)
For some reason you are probably getting an error after the first file
is moved to the Trash. When you get an error the "try" statement goes
directly to its "on error" clause if there is one, if not then it just
goes directly to the "end try". You can see the error if you do
something like this:
----------
tell application "Finder"
try
delete file "A" of desktop
delete file "B" of desktop
delete file "C" of desktop
on error error_message number error_number
display dialog error_message buttons {"OK"} default button 1
end try
end tell
----------
2)
There are two ways of taking care of the possibility of a missing file.
One is to put each delete statement in its own try block:
----------
tell application "Finder"
try
delete file "A" of desktop
on error error_message number error_number
display dialog error_message buttons {"OK"} default button 1
end try
try
delete file "B" of desktop
on error error_message number error_number
display dialog error_message buttons {"OK"} default button 1
end try
try
delete file "C" of desktop
on error error_message number error_number
display dialog error_message buttons {"OK"} default button 1
end try
end tell
----------
The other is to test to see if the file is there before deleting it:
----------
tell application "Finder"
try
if exists file "A" of desktop then delete file "A" of desktop
if exists file "B" of desktop then delete file "B" of desktop
if exists file "C" of desktop then delete file "C" of desktop
on error error_message number error_number
display dialog error_message buttons {"OK"} default button 1
end try
end tell
----------
