Practical use cases

Less mechanical sorting, more focus

Countdown assets

Scan order repair

Fix reversed scan order without altering the PDF or image contents.

Newest first

Give recent files the highest or lowest number, then fine-tune by dragging.

FAQ

Questions before you begin

Does reverse numbering alter file contents?

No. It only changes copied filenames and their order inside the downloaded ZIP.

Can reverse numbers be zero padded?

Yes. Choose one to four digits, such as 010, 009 and 008.

Can I drag files before numbering them?

Yes. Numbering always follows the current order shown in the preview.

COMMON TASKS

Reverse-number files with a descending sequence

Use reverse numbering when scan order is backwards, newest files should come first, or assets need countdown names such as 10, 09 and 08. Arrange the files first, then generate the descending sequence.

Number files in reverse

Create a descending sequence from the order shown in the preview without altering the contents of the source files.

Countdown numbering with padding

Generate 10, 09, 08 or 010, 009, 008 style names so the sequence remains easy to scan and sort.

Reorder before numbering

Fix a reversed scan or delivery order first, then let the descending counter follow the final arrangement.
