tree /a /f > output.doc

Output.doc is the document file where the entire directory tree is saved.
Open it to check out the tree!

Open a Command Prompt or Terminal: On Windows, press Win + R, type cmd, and hit Enter. On macOS or Linux, open the Terminal. Navigate to the Directory: Use the cd command to navigate to the directory where your files are located. For example:

cd /path/to/your/directory

Delete the Files: Run the following command to delete all “._Thumbs.db” files in the directory and its subdirectories:

del /s /q ._Thumbs.db

/s searches for files in subdirectories. /q suppresses confirmation prompts. If you’re on macOS or Linux, use the rm command instead:

find . -type f -name "._Thumbs.db" -exec rm {} \;

Confirm Deletion: Verify that the files have been deleted by checking the directory. Remember to replace /path/to/your/directory with the actual path to your file structure. Be cautious when deleting files, especially system files, to avoid unintended consequences.
