Choose the analyzer for your file task
These tools inspect different kinds of file evidence, so the right choice depends on whether you have an archive, a folder, a text file, a PDF, or a set of files to compare. Use the report that answers your specific question rather than treating the analyzers as interchangeable.
- Archive Inspector reads ZIP, TAR, GZIP, and TAR.GZ/TGZ entries, sizes, compression ratios, timestamps, and warning indicators without extracting files.
- Duplicate File Finder groups files when both their sizes and SHA-256 content hashes match, identifying byte-identical duplicates and the space those groups could recover.
- Folder Size Analyzer reports storage usage from file and folder metadata, including totals, largest items, type breakdowns, and a treemap without reading file contents.
- File Age & Path-Length Analyzer reports modified-date age buckets, inactive candidates based on a chosen threshold, and relative, basename, and simulated full-path lengths.
- File Encoding & Line-Ending Analyzer reports encoding and BOM indicators, line-ending style, byte/line/word/character counts, invalid or replacement sequences, and a preview.
- File Type Detector identifies formats from file signatures or magic bytes and compares the result with the filename extension.
- PDF Document Inspector reports PDF page structure, dimensions, rotation, encryption and permission indicators, metadata, fonts, bookmarks, and hyperlinks.
Match the input to the report you need
Start with the evidence you want to inspect. Choose Archive Inspector for archive structure and entry-level warnings; it does not repair or create archives. Choose Duplicate File Finder when you need to compare exact file contents—filenames alone do not determine a match.
For storage questions, use Folder Size Analyzer, which works from names, sizes, and last-modified dates rather than opening file contents. Use File Age & Path-Length Analyzer for date-based review and path-length checks, not for inspecting file contents.
For text-file diagnostics, open File Encoding & Line-Ending Analyzer. If the filename extension may not reflect the bytes at the start of a file, use File Type Detector. For PDF structure rather than OCR, general content extraction, or editing, use PDF Document Inspector.
A practical file-analysis workflow
Begin by identifying the input: an archive, a group of files, a folder, a text file, a single unknown file, or a PDF. Open the matching page and provide that tool's file, folder, or archive input. Each child page has its own interface rather than one universal analysis workflow.
Review the tool-specific report, which may include summaries, tables, filters, previews, or visualizations. For example, you can open the archive report, review duplicate groups, or review PDF pages and metadata. Where an inspected tool documents an export control, use that control from the tool's own report; the tools do not all provide the same outputs or filters.
The inspected analysis tools are read-only: they do not delete, rename, modify, repair, or rewrite the analyzed inputs.
Limits that affect interpretation
- Archive Inspector reports structural and compression information, but it does not extract, repair, perform general malware scanning, or establish overall archive integrity.
- Duplicate File Finder identifies exact byte-identical groups using size and SHA-256; it does not delete files.
- File Age & Path-Length Analyzer depends on readable modified dates and uses the selected threshold for inactive candidates.
- File Encoding & Line-Ending Analyzer uses BOM and byte-pattern heuristics, so some legacy-looking data remains ambiguous or unidentified.
- File Type Detector reads a limited header of up to 4,160 bytes and can compare the detected format with the claimed extension. A signature result does not prove that the entire file is valid or safe.
- Folder Size Analyzer uses file metadata and does not inspect file contents.
- PDF Document Inspector depends on what its parser can read; damaged, encrypted, or unusual PDFs may produce incomplete results. It does not remove protection or edit the document.
