Apple Script：将文件（从提示中选择）复制到另一个位置

Question

I am struggling with my Apple Script. I am asking to select a file and the selected file needs to be copied to another location. I am new to Apple Scripting, so probably made some mistake. I tried different versions with "copy" instead of "duplicate" or "alias" instead of "file", but nothing worked so far. Hope, somebody can help me figure this out.

This is what I scripted so far (I get an AppleEvent timed out):

set DefaultPath to POSIX file "/Users/jan/Library/Mobile Documents/com~apple~CloudDocs/FOLDER/Test"
    set DestFolder to "/Users/jan/Library/Mobile Documents/com~apple~CloudDocs/FOLDER/Destination"
    set theFile to (choose file with prompt "Select file:" default location (DefaultPath))
    tell application "Finder"
        duplicate theFile to folder DestFolder
    end tell

Answer 1

The problem is that the Finder doesn't support POSIX paths.

I recommend to use a relative path path to library folder from user domain and HFS paths (colon separated)

To satisfy the location parameter of choose file put the alias keyword in front of the (HFS) path

set cloudDocs to (path to library folder from user domain as text) & "Mobile Documents:com~apple~CloudDocs:"

set DefaultPath to cloudDocs & "FOLDER:Test:"
set DestFolder to cloudDocs & "FOLDER:Destination:"
set theFile to (choose file with prompt "Select file:" default location (alias DefaultPath))
tell application "Finder"
    duplicate theFile to folder DestFolder
end tell
