How to hide all file extensions in subdirectories of a given folder?
Solution 1:
You can easily do this in Terminal with the SetFile
command:
To hide file extensions in a directory and all sub-directories:
cd <path to directory>
find . -name "*.*" -exec SetFile -a -E '{}' \; | echo "hiding extensions"
(can change the second * to a particular extension type if you choose)
To show file extensions in a directory and all sub-directories:
cd <path to directory>
find . -name "*.*" -exec SetFile -a -e '{}' \; | echo "showing extensions"
Solution 2:
Ok, I found a solution using Hazel:
I created a rule based on their posting How to get Hazel to go into subfolders:
If (…) Kind is Folder
Do the following (…) run rules on folder contents
The next rule selects a certain set of files, e.g.
If (…) Kind is pdf
Do (…) Run AppleScript embedded script
The script is
tell application "Finder"
set extension hidden of theFile to true
end tell
I defined more conditions more different file types, so it doesn’t work on all files as requested. With a limited number of different file types this should be no problem.
