Does preview scan for malware?

No. Preview lists archive information and members; it is not malware scanning.

Use the exact relative member path from preview and reject .., absolute or drive-letter paths, NUL, and shell syntax.

What is the size limit?

Each tool exposes a 100 MB input file limit; expanded and output limits are not uniformly published.

Archive Preview, Selective Extraction, and Format Conversion

Goal and scope

Preview supported archives, extract one verified member, and convert the result.
Use this guide to turn the stated scope into a reviewable result. Keep the source, intermediate outputs, and decisions together so the next person can understand what was checked and why.

Prepare evidence and make decisions

Use an archive you are authorized to process and keep each input at or below 100 MB.
Preview first; use only the exact relative member path with no .., absolute or drive-letter prefix, NUL, or shell syntax.
Decision: Which tool and path should I choose?. Use zip-preview, 7z-preview, tar-preview, tar-gz-preview, or gzip-preview for the matching format. Then choose the matching selective extractor or zip-to-, tar-to-, or 7z-to-* converter; copy the path from preview and never use a host OS path.

Complete the workflow

1. Preview

List the archive and record member paths, counts, and sizes before processing. Use zip-preview, 7z-preview, tar-preview, tar-gz-preview, gzip-preview.

2. Extract selectively

Copy one verified relative path and extract only that member; use gzip-extractor for a GZIP file without member selection. Use zip-selective-extract, 7z-selective-extract, tar-selective-extract, tar-gz-selective-extract, gzip-extractor.

3. Convert and verify

Choose the source-to-target converter, check the returned format and size, and preview an archive result again. Use zip-to-7z-converter, zip-to-gz-converter, zip-to-tar-converter, tar-to-7z-converter, tar-to-gz-converter, tar-to-zip-converter, 7z-to-gz-converter, 7z-to-tar-converter, 7z-to-zip-converter.

Verify the result before handoff

Preview records the expected members, counts, and sizes, and every input is at most 100 MB with a safe relative path.
Extraction or conversion returns a non-empty result with the expected filename or target format and size; re-preview archive output before delivery.
