Important information, tips for the "REN" command

There are a few important points to note when using the `REN` (Rename) command in the Windows Command Prompt: 1. Spaces and special characters: If file or directory names contain spaces or special characters, they must be enclosed in double quotes. This ensures that the `REN` command interprets the file or directory name correctly.

   REN "Old Name.txt" "New Name.txt"
   
2. File Extensions: The `REN` command can also be used to change file extensions. Make sure to use the correct syntax.

   REN document.txt document.doc
   
3. Wildcards and Patterns: The `REN` command supports wildcards, which are useful for renaming multiple files at once. For example:

   REN *.txt *.bak
   
This changes the file extensions of all text files in the current directory from ".txt" to ".bak". 4. `/S` option (recursive): The `/S` option can be used to apply the command recursively to subfolders. Be careful when using this option to avoid unwanted renames in many files and directories.

   REN /S OldMain Directory NewMain Directory
   
5. Be careful when overwriting: Make sure that the new name is not already in use by an existing file or directory. The `REN` command overwrites without warning. 6. Perform a backup: Especially when renaming multiple files or directories, it is advisable to perform a backup to avoid accidental data loss. It is important to use the `REN` command with caution, especially when using wildcards or the recursive option. Carefully check the intended files or directories to be renamed to avoid unwanted consequences.
