Batch Filename Pattern Generator

Renaming 200 files by hand is how typos and collisions happen.

Batch file naming — for invoices, exported reports, photo sets, or generated documents — is a common source of avoidable errors when done manually: inconsistent zero-padding (file9 sorting after file10), typos across a long sequence, or a pattern that unintentionally produces duplicate names once actual data is substituted in. This tool genuinely substitutes {n} (with configurable zero-padding), {name}, {date}, and {ext} placeholders across a batch of any size up to 5,000 files, and actively checks the generated batch for duplicate filenames — flagging it immediately if your pattern isn't specific enough to guarantee uniqueness.

• →Genuinely substitutes {n}, {name}, {date}, {ext} placeholders, not a static example list
• →Configurable zero-padding ensures correct sort order (file001, file002... not file1, file10, file2)
• →Actively detects and flags duplicate filenames your pattern would otherwise silently produce
