Frequently asked questions
What is a file duplicator?
A file duplicator is a utility that creates multiple exact clones of a single source file. It saves time by generating sequential duplicates in bulk rather than requiring manual copy-and-paste actions.
Are my files uploaded to your servers?
No. The tool runs directly in your web browser using client-side JavaScript, meaning your original file and its copies never leave your computer.
How do I download hundreds of duplicate files at once?
The tool bundles all generated file copies into a single compressed ZIP folder, allowing you to download the entire collection with one click.
Is there a limit on file size or number of copies?
Because the tool operates within your browser memory, limits depend on your device's available RAM. For best performance, replicate smaller files when generating thousands of copies.
Is the File Duplicator free to use?
Yes, the tool is completely free to use with no account creation or subscription required.
