Root Cause Analysis

deepin-compressor.xml only registered the 7z split archive glob pattern (*.7z.*), but did not register any MIME type or glob pattern for zip split archives (.zip.001, .z01, etc.). The system freedesktop.org.xml also only covers *.zip/*.zipx without split suffixes. As a result, the file manager falls back to content detection for .zip.001 files → returns text/plain → displays a text icon, while normal .zip files match application/zip → display the archive icon, causing icon inconsistency.

Fix

Add zip split archive MIME type registration in deepin-compressor.xml, mirroring the existing 7z split archive registration. Register application/zip type with glob patterns *.zip.[0-9][0-9][0-9] and *.z[0-9][0-9], and set generic-icon name="deepin-compressor".

Change Safety Assessment

• Risk level: Low
• This change only adds new glob patterns to the MIME type registration file, without modifying any existing registrations or code logic
• No existing behavior is altered; only zip split archive files gain correct MIME type detection and icon display

Influence

• Test zip split archive (.zip.001) icon display in file manager
• Test zip split archive (.z01) icon display in file manager
• Verify normal .zip files still display the correct icon

根因分析

deepin-compressor.xml 仅注册了 7z 分卷压缩包的 glob 模式（*.7z.*），未为 zip 分卷压缩包（.zip.001、.z01 等）注册任何 MIME 类型或 glob 模式。系统 freedesktop.org.xml 也仅覆盖 *.zip/*.zipx，不含分卷后缀。因此文件管理器对 .zip.001 等文件回退到内容检测 → 返回 text/plain → 显示文本图标，而普通 .zip 匹配 application/zip → 显示压缩包图标，导致图标不一致。

修复方案

在 deepin-compressor.xml 中新增 zip 分卷压缩包 MIME 类型注册，镜像现有 7z 分卷注册方式。注册 application/zip 类型，添加 *.zip.[0-9][0-9][0-9] 和 *.z[0-9][0-9] glob 模式，设置 generic-icon name="deepin-compressor"。

改动安全评估

• 风险等级：低
• 本次改动仅在 MIME 类型注册文件中新增 glob 模式，不修改任何已有注册或代码逻辑
• 不改变任何现有行为，仅使 zip 分卷压缩包文件获得正确的 MIME 类型检测和图标显示

影响范围

• 测试文件管理器中 zip 分卷压缩包 (.zip.001) 图标显示
• 测试文件管理器中 zip 分卷压缩包 (.z01) 图标显示
• 验证普通 .zip 文件图标显示不受影响

PMS: BUG-268375

Summary by Sourcery

Register MIME metadata for split ZIP archives so they are recognized and displayed consistently with regular archives.

New Features:

• Register split ZIP archive filename patterns with the application/zip MIME type and compressor icon.

Bug Fixes:

• Ensure .zip.001 and .z01 split archives receive correct MIME detection and file manager icons instead of being treated as plain text.

Reviewer's Guide

The PR extends the MIME database with two split-ZIP glob patterns under application/zip, mirroring the existing split-7z registration and preserving the existing archive icon behavior for normal ZIP files.
