Hernoem baie lêers gelyktydig en skep ’n lêerlys

Hernoem lêers in stapels met voorvoegsel, agtervoegsel, nommering en soek-vervang, of voer ’n inventaris uit as CSV, TXT of JSON in die blaaier. Niks word opgelaai nie.

Voeg voorvoegsels, agtervoegsels en nommers by, vervang teks in name en laai ’n ZIP af—of bou ’n gidslys en voer uit.

Browsers cannot rename files directly on your disk. This tool previews new names and downloads copies (or a ZIP) with those names. Your originals stay unchanged.

What is File Utility?

One browser workspace to batch-rename files for download and to generate file inventories as CSV, TXT, or JSON—without uploading files to a server.

Rename multiple files at once

Apply prefixes, suffixes, sequential numbers, find & replace, spacing rules, and case changes. Preview every new name, then download one file or a ZIP of renamed copies.

Add prefixes and suffixes

Prefixes attach before the base name. Suffixes insert before the extension, so photo.jpg with -edited becomes photo-edited.jpg.

Number files automatically

Enable sequential numbering with start, increment, and zero padding. Place numbers before the name, after the name, or replace the base name.

Find and replace filename text

Replace text in the base filename only. Extensions stay separate unless you change extension case.

Generate a file list

Build an inventory of selected files or a folder (when the browser supports it). Include name, extension, size, type, last modified, and relative path.

Export file names to CSV

Export the filtered list with the columns you selected. TXT can export names only; JSON exports structured rows.

Create a folder file inventory

Use Choose folder when available to include relative paths such as photos/2026/image01.jpg, then export for records or spreadsheets.

Why browsers cannot rename local files directly

Web pages are not allowed to change names on your disk. NEXNARA downloads newly named copies instead. Delete or replace originals yourself if you want only the new names.

Privaatheid

Filenames and sizes are processed in your browser. Files are not uploaded to a NEXNARA server. ZIP downloads read file bytes only to pack the archive locally.

Gereelde vrae

Can a website rename files directly on my computer?

No. This tool downloads renamed copies (or a ZIP). Your original files stay as they are.

Can I rename hundreds of files at once?

Yes. Select many files, preview names, then download a ZIP. Very large sets may use more memory while zipping.

Can I add sequential numbers?

Yes. Enable sequential numbering, set start/padding, and choose before, after, or replace.

Can I keep file extensions unchanged?

Yes. Extension case can stay as-is. This tool does not convert file formats.

Can I replace part of a filename?

Yes. Use Find and Replace on the base name. Optional case-sensitive matching is available.

Can I generate a list of files in a folder?

Yes. Use File List Generator and Choose folder when your browser supports directory picking.

Can I export filenames to CSV?

Yes. Export CSV with the columns you selected. TXT and JSON are also available.

Does NEXNARA upload my files?

No. Work stays in your browser.

Can I include file sizes and dates?

Ja. Grootte en laas gewysig kom van die File API. Skeppingsdatum word nie beweer nie.

Can I include subfolder paths?

When folder selection provides relative paths, enable the Relative path column.
