How does the File Extension Extractor parse file paths and URLs?

Paste file names, directory listings, or URLs. The parser isolates the final dot delimiter, extracts the extension, and handles complex multi-dot extensions (e.g. .tar.gz).

Can I categorize and tally file extensions by frequency?

Yes. The tool automatically tallies counts for each unique extension (e.g. .pdf, .jpg, .csv) and groups them by category (Documents, Images, Archives, Code).

How does it handle file names without extensions?

Files without extensions are categorized into a dedicated No Extension group, ensuring accurate audits of system and binary files.

Is there any limit on the number of file names I can analyze?

No. Because all parsing executes locally in your browser memory, you can analyze lists containing tens of thousands of file paths instantly.
