How to Insert Characters in File Names at a Position

Sometimes a prefix or suffix isn't enough — you need to insert text in the middle of a filename, such as adding a category code after a fixed-length ID, or inserting a separator between two existing parts of the name. Insert at Position gives you that level of control, letting you specify exactly where in the filename the new text should be added, rather than only at the very start or end.

This is especially useful for filenames that already follow a consistent structure, where the insertion point is the same character position across every file in the batch.

1. Install Turbo Bulk Renaming Tool on your Windows PC.
2. Open the app and load the folder containing the files you want to modify.
3. Select the Insert at Position renaming rule.
4. Enter the text you want to insert and specify the character position where it should be placed.
5. Check the live preview to confirm the text lands in the correct spot across all filenames.
6. Click Rename to apply the insertion to every selected file at once.

• Insert text at any character position within the filename, not just the start or end
• Works consistently across filenames that share a similar structure
• Live preview confirms the exact insertion point before you commit
• Can be combined with other rules, such as Case Conversion, for further refinement
• Recursive sub-folder support for applying the same insertion across nested folders
• Conflict detection flags any resulting duplicate filenames before renaming
