Okay total different approach.
Use AppleScript only.
Step 1: Create folders (input and output)
Step 2: Create script
on adding folder items to theAttachedFolder after receiving theNewItems
set text item delimiters to "."
set outputFolder to POSIX file "/Users/YOURUSERNAME/Desktop/random/output/"
tell application "Finder"
set all_files to every item of theNewItems as list
--now we start looping through all selected files. 'index' is our counter that we initially set to 1 and then count up with every file.
repeat with index from 1 to the count of all_files
set x to ""
repeat 10 times
set x to x & some item of "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890"
set new_name to x
--using our index, we select the appropriate file from our list
set this_file to item index of all_files
set file_name_count to text items of (get name of this_file)
--lets check if the current file from our list (based on index-number) has even any file-extension
if number of file_name_count is 1 then
--file_name-count = 1 means, we extracted only 1 text-string from the full file name. So there is no file-extension present.
set file_extension to ""
--yup, we are currently processing a file that has a file-extension
--we have to re-add the original file-extension after changing the name of the file!
set file_extension to "." & item -1 of file_name_count
--let's rename our file and add the file-extension to it
set dupeFile to duplicate this_file to outputFolder
set the name of dupeFile to new_name & file_extension as string
end adding folder items to
Step 3: Save script in ~/Library/Scripts/Folder Action Scripts/
Step 4: Right mouse click on input folder > Services > Folder Action Setup
Step 5: Connect script to folder.
Left part you add your input folder, click on folder in the left list.
At the right list you choose your script.
Step 6: Add a bunch of files in the input folder. They are getting random names in the output folder and are deleted from the input folder.
Do not forget to change the outputFolder value inside the script!
