Cleaning up hundreds of files at once
Photos from a trip, scanned pages, or exported reports often arrive with messy, inconsistent file names. Windows' built-in bulk rename feature needs no extra software β select the files, give them a shared base name, and File Explorer numbers the rest automatically.
Sort first, rename second
The order files get numbered in follows the order they are currently sorted or selected in, so it pays to sort the folder by name, date, or however you want the final sequence to read before you start renaming. Getting the sort order right first saves you from having to redo the whole batch.
Frequently Asked Questions
What determines the order the numbers are assigned in?
By default, numbering follows the current sort order of the files (name, date, etc.) or the order you selected them in, so it helps to sort the folder the way you want beforehand.
Can I undo a rename if I make a mistake?
Yes β if you catch it right away, pressing Ctrl+Z (Undo) will revert the batch rename.
