# Randomizing filenames

You can use Renamer to generate random filenames.

## To randomize your filenames:

Drag the files you want to rename from the Finder to the file table.

Click and choose Numbers.

Click Random.

Click Apply.

By default Renamer will generate a unique random number for each file in the range of the number of files. For example, if you added 10 files to be renamed, the files will have random names in the range 1, 2, … 10. You can change this behavior by setting a minimum number of digits, in which case the missing digits are padding with zeros. In our example the files would then be renamed 01, 02, … 10.

To insert text into the filenames, enter that text into the “Attach text” box. From the Format pop-up menu choose “Original – text – number” to have that text inserted before the number, or “Number – text – original” to have it inserted after the number.

By default, Renamer will include the original filename in the new filename. To discard the original filename from the new name, choose either “Text – number” or “Number – text” from the Format menu, depending on whether you want the number to appear after or before the attach text.

To regenerate the random filenames, click .
