Renaming files during copying or moving refers to changing the destination filename as part of the transfer operation itself. This is distinct from simply copying/moving a file to a new location with its existing name and then manually renaming it afterward. Most modern operating systems and file management tools explicitly support changing the name as you perform the copy or move action, usually through a dialog box prompt that appears after initiating the transfer command but before the operation completes.

For example, when copying a file named "Report_Draft.txt" to a folder containing an existing file with the same name, you might be prompted to rename the copy to "Report_Draft_v2.txt" to avoid overwriting. Similarly, when moving a batch of vacation photos, you could explicitly rename the destination file to "Spain_Trip_Day1.jpg" as you move it from your camera's temporary folder to your organized "Vacations" directory. This feature is available in standard file explorers (like Windows File Explorer or macOS Finder) and command-line tools (using cp or move with a new destination filename).

The key advantage is efficiency, saving users from performing multiple steps to achieve the final desired filename and location, which is particularly useful for avoiding name collisions and improving organization. A limitation is that careless renaming during the operation could lead to accidental overwrites or file confusion if done without attention. Consistent naming practices are crucial. The feature's ubiquity encourages clearer file organization systems and reduces friction in daily computer workflows.
