Auto-Detect Resolution, File Type & Date When Renaming Files

You're renaming a batch of exported assets. Each file needs the resolution in its name — 1920x1080, 300x250, 1080x1920. So you open each file, check the dimensions, type them into the filename, and move to the next one.

Now multiply that by 200 files.

This is the kind of work that feels productive but isn't. It's slow, it's tedious, and every manual entry is a chance for a typo that sends the wrong file to the wrong placement.

There's a better way.

What Is File Metadata?

Every file on your computer carries metadata — information embedded in the file itself that describes what it is. Depending on the file type, this can include:

• Date created and date modified
• Resolution (width × height in pixels)
• File type and format
• File size
• Camera model and shoot settings (for RAW photos)
• Duration (for video files)

This information already exists. You don't need to look it up — you just need a tool that reads it for you.

The Manual Way Is Costing You More Than You Think

For a designer managing campaign assets, resolution is almost always part of the file naming convention. 300x250_banner_nike_v2.jpg is a standard format in most agencies.

But getting that 300x250 into the filename manually means opening each file, reading the dimensions from the file info panel, and typing it correctly. For 20 files, that's annoying. For 200, it's a significant chunk of your day.

The same problem applies to dates. If your naming convention includes the creation date — common for photographers, video teams, and anyone archiving work — you're either relying on memory or opening file properties one by one.

The error rate on this kind of manual work is not zero. And one wrong dimension in a filename can mean a banner gets served at the wrong size.

Smart Detection: Let the File Tell You What It Is

TaxoFlow's Smart Detection reads your files' metadata automatically and makes it available as variables in your naming template.

When you build a template like [date]_[client]_[width]x[height]_[version], TaxoFlow fills in the date, width, and height from each file's actual metadata. You don't type anything. You just confirm the preview looks right and apply.

This works across file types: Images and design exports — resolution, dimensions, format, creation date RAW photos — date, camera model, shoot settings Video files — resolution, duration, format Documents — creation date, modification date, file type

The result is file names that are accurate by definition. The data comes from the file itself, not from a human reading and retyping it.

What This Looks Like in Practice

A video editor exports 80 files from a campaign. Each needs to be named with its resolution and export date. Without Smart Detection:

• Open file properties for file 1 → read resolution → type into name → repeat 79 more times
• Total time: 30–45 minutes
• Error risk: high

With TaxoFlow Smart Detection:

• Build template once: [date]_[campaign]_[width]x[height]
• Apply to all 80 files
• Preview, confirm, done
• Total time: under 2 minutes
• Error risk: zero — the data comes from the file itself

Stop Reading File Properties Manually

If your workflow involves putting metadata into filenames — resolution, date, file type, anything — you're doing work that a tool should be doing for you.

TaxoFlow is a native desktop app for Windows and Mac. Smart Detection is built in. Your naming templates can reference any metadata field your files contain. One-time purchase, $4.99.

The file already knows what it is. Let it tell you.
