Archive extraction and repackaging: how 7Z becomes TGZ

The entries in 7Z are unpacked and a new TGZ package is built from their filenames and folder paths. Compression is rebuilt; archive-level encryption, comments, and recovery records are not portable assumptions. The 7Z reader must resolve solid compression blocks and optional encrypted headers before it can enumerate individual entries. TGZ is the short spelling for a Gzip-wrapped TAR package; validation must decompress the outer stream and then inspect the complete inner member tree.

Read as a compressed archive with strong ratios and optional AES encryption. Rebuilt as a TAR folder stream compressed as one Gzip payload.

INPUT MODEL

7Z

7Z archive format

Used for compressed storage for a group of files and folders.

Family: Archives
MIME: application/x-7z-compressed

→

OUTPUT MODEL

TGZ

TGZ archive format

Designed for packaging files and folder structures.

Family: Archives
MIME: application/x-gtar

Acceptance evidence for the converted TGZ

BEFORE

Record the 7Z evidence before conversion

Extract the result with the recipient's actual archive app and compare the complete folder tree.

AFTER

Test the TGZ file in its receiving workflow

Decompress and extract both layers, then compare paths, Unicode names, file counts, permissions, links, and checksums.

Reading 7Z correctly and satisfying what TGZ expects

What can fail when 7Z archive format is interpreted

Some built-in operating-system extractors cannot open 7Z packages, and encrypted headers can hide filenames.

TGZ

What TGZ archive format cannot safely promise

Gzip protects the TAR byte stream but does not independently validate each member, and non-Unix tools may alter permissions or links.

ENGINE

How the TGZ writer handles this route

a TAR folder stream compressed as one Gzip payload is what gets written, labeled as application/x-gtar. Whether that actually opens depends on the receiving application, not on the file extension.

The delivery decision for this 7Z to TGZ route

TGZ is the right move once the recipient's archive tool cannot reliably open 7Z; judge success by the extracted folder tree, not by the new package's file size.

What changes between the 7Z model and the TGZ deliverable

The source stores a compressed archive with strong ratios and optional AES encryption; the destination stores a TAR folder stream compressed as one Gzip payload. Compare application metadata after that structural change.
Treat 7Z-specific metadata fields as optional in the TGZ result until you have actually confirmed they survived.
