📁 File Helpers

Check a file before you open or share it

Three quick inspectors in one place: see a file's basic properties, look inside a ZIP archive without extracting it, and preview the first rows of a CSV — all processed directly in your browser with nothing uploaded.

File Info Viewer

Select one or more files to see their type, exact size and last-modified date — handy for quickly checking several files at once before deciding what to do with them.

ZIP Inspector

See exactly what's inside a ZIP file — file count, estimated uncompressed size, and a full file listing — without extracting it to your device first.

CSV Preview

Get a quick table view of a CSV's first rows and column headers, useful for confirming a file's structure before importing it somewhere else.

Using this in a Central Government office

These are the small file-handling jobs that come up around document work — checking what a file actually is, renaming a batch consistently, and confirming that a file you received is the same one that was sent.

Where this comes up

• Consistent naming before a submission — annexures named in the order they are referred to, so the receiving end can follow the bundle.
• Checking a file's real type when an attachment will not open or was renamed with the wrong extension.
• Confirming a received file is unaltered against a checksum supplied by the sender.

On file naming for official records

A file that will sit in a record for years should carry enough in its name to be identifiable without opening it: the subject, the document type and the date, in a format that sorts correctly. Dates written as YYYY-MM-DD sort chronologically on their own; dates written as DD-MM-YYYY do not. This costs nothing at the time and saves real effort when someone has to find the document three years later.
