Inspect
Drop any file or folder and get structured facts — name, size, MIME, timestamps, and type-specific fields like EXIF, ID3 tags, or PDF page count.
Zentro
Desktop File And Folder Metadata Inspector
Drop any file or folder onto a single window, preview it, and inspect rich metadata without opening a dozen separate tools. Images, PDFs, audio, video, archives, Office documents, and plain text each get a tailored detail panel.
Everything You Need To Inspect Files
Preview and details stay in sync. The left pane shows a live preview where supported; the right pane is a dynamic registry of detail blocks driven by file category.
Preview
Images render inline. PDFs scroll via PDF.js. Text files show capped snippets. Unsupported types get a clear placeholder instead of a broken preview.
Export
Save the full metadata payload as JSON from the toolbar, or use Show In Folder to reveal the selected path in your system file manager.
Archive
Create zip, tar, gz, tgz, or 7z archives with compression presets and a managed job queue. Extract and inspect archive contents without a separate utility.
Supported File Categories
Each path is classified by magic bytes and extension, then routed to a category-specific extractor in the main process.
- folder
- image
- svg
- audio / video
