Rename Multiple Files at the Same Time
Many know the problem: Files have invalid characters in their names or have to be renamed for other reasons. If there are only one or two files, it is done quickly. But if there are many of them, renaming them all is a time-consuming task in Windows Explorer. Fortunately TreeSize assists you with this task!
With Bulk Rename you can rename as many files as you like in one swing. The easy to use dialog offers several operations that can be used to modify the file name:
- Replace text, optionally by using a regular expression.
- Insert the selected text as a prefix, suffix or at a specific position.
- Serialize the file names.
- Delete a certain text within the filenames or any text at a certain position.
A preview allows to see which renaming operations effectively is going to be performed, which prevents wrong bulk renamings.
