Practical use cases

Less mechanical sorting, more focus

Report attachments

Lock attachments into 01, 02 and 03 so recipients open the right file first.

Product images

Create clear display-order names such as SKU_001 and SKU_002.

Course materials

Start from a chosen chapter number and leave room with a custom increment.

FAQ

Questions before you begin

Can numbering start at zero or another number?

Yes. Set the start to zero or any non-negative integer.

Can I count by 5 or 10?

Yes. The increment is editable and is not limited to one.

Can the number appear after the name?

Yes. Choose before or after and see the exact result immediately.

COMMON TASKS

Number files in sequential order with zero padding

Keep report attachments, product photos or scanned pages in a clear 001, 002, 003 sequence. Arrange the files first, then choose the start, increment, padding and number position. Check the proposed names before downloading so the recipient can sort the copies predictably.

Number the current file order

The counter follows the order shown in the preview, so you can rearrange files before generating the final sequence.

Choose start and increment

Start at zero or another non-negative number and count by a custom step such as 1, 5 or 10.

Zero pad for predictable sorting

Use 01, 001 or 0001 style numbering so filename sorting stays stable in common file managers.
