Untouch

Untouch is a free command line tool that allows you to easily change file creation dates. This can be useful if you need to hide the fact that you've edited a file, or if you want to synchronize the creation dates of files in different directories.

Untouch supports the following commands:

- `-f` or `-force`: Changes the creation date of a file to the previous one, regardless of whether the file has been edited in the meantime.

- `-s` or `-sub` or `-subdir` or `-subdirs`: Processes files in subdirectories as well.

- `-l` or `-log`: Creates a `untouch.log` file in each directory that contains information about files whose creation dates have been changed.

- `-q` or `-quiet`: Disables progress messages.

To use Untouch, navigate to the directory that contains the files you want to modify and run the `untouch` command with the appropriate switches. For example, the `untouch -f -.txt` command will change the creation dates of all files with the `.txt` extension to the previous one.

Untouch is a utility that can be used for a variety of purposes. If you need to change the creation dates of files, Untouch is a great choice.
