There are a large number of folders on the computer that need to have a prefix added uniformly. Renaming them one by one manually is too slow. Is there any way to add prefixes in batches with one click? Below, I will share 3 simple and easy-to-use methods to add a prefix to all folders uniformly in batches with one click. It can be done quickly in just a few seconds, completely without manual operation. Each method comes with a detailed illustrated operation tutorial. You can easily complete it by following the tutorials!
Use Cases for Batch Adding Prefixes to Folders
1. When folders from different departments in a company are stored together, finding files requires opening each one individually, which is very tedious. Batch adding prefixes like Administration_, HR_, Finance_, etc., to folders will group folders from the same department together, making the structure clear and enabling quick file searches.
2. When a computer contains a large number of folders with similar content, such as contracts, quotations, and liaison materials, it is difficult to identify which project these materials belong to without clear indication. Therefore, it's necessary to uniformly add prefixes to folder names, which can prevent naming conflicts and automatically group folders for different projects.
3. Folder materials collected from various sources often have chaotic names without a unified naming convention. Batch adding time or department prefixes to these folders allows for orderly file arrangement, making organization and archiving clearer.
