COMPRESSION MANAGER é um utilitário gráfico leve para Windows projetado para empacotamento, extração e verificação de integridade de arquivos e pastas. Oferece suporte a múltiplos formatos (ZIP, 7Z, TAR, WIM e outros reconhecidos pelo 7‑Zip), seleção de vários diretórios de saída, métodos de compressão configuráveis, fila de processos e operação via arrastar-e-soltar. A interface é multilíngue (pt_BR / en_US) e preparada para empacotamento como executável (distribuição sem necessidade de instalação manual de dependências Python).
- Compressão de pastas e arquivos nos formatos .zip, .7z, .tar e .wim.
- Extração de arquivos compactados em diversos formatos suportados pelo 7‑Zip (.rar, .zip, .7z, .tar, .wim, .bz2, .tar.xz, .tgz, .tar.gz, .zipx, .lzh, .iso etc.).
- Seleção e manutenção de múltiplos diretórios de saída por formato.
- Arrastar e soltar (drag & drop) para adicionar arquivos e pastas às listas de entrada e saída.
- Métodos de compressão configuráveis por formato (níveis 0–9 onde aplicável) e persistência das preferências.
- Modo "Armazenar como" para criar pacotes com ajustes específicos sem alterar as configurações padrões.
- Atualização de arquivos existentes (opção de atualizar arquivos compactados em vez de recriá‑los).
- Teste de integridade de arquivos compactados (comando "t" do 7‑Zip) para validar pacotes.
- Fila de compressão: novos pedidos podem aguardar enquanto outra tarefa do mesmo formato é executada.
- Mensagens e diálogos traduzíveis; troca de idioma em tempo de execução.
- Janela "Sobre" que exibe texto de descrição, histórico, licenças, avisos e política de privacidade carregados a partir dos recursos incluídos.
- Operação offline: todos os dados são locais (arquivos de configuração e preferências armazenados no diretório persistente do usuário).
- Base GUI: PySide6 (Qt) com widgets personalizados para facilitar seleção múltipla e arrastar-e-soltar.
- Motor de compressão/extração: 7‑Zip (7zG.exe). O aplicativo procura por um executável 7‑Zip incluído junto ao aplicativo (diretório "7-Zip") ou nos caminhos padrão do sistema (Program Files). Se o 7‑Zip não for encontrado, operações de compressão/extracção não funcionarão e o usuário será avisado.
- Threads: operações de compressão, extração e verificação são executadas em threads para manter a interface responsiva.
- Persistência: preferências de compressão e idioma são salvas em arquivos JSON no diretório persistente do usuário (obter_caminho_persistente).
- Projetado para ser empacotado como executável para Windows, incluindo recursos e traduções.
- Quando distribuído como instalador/executável, o usuário final não precisa instalar dependências Python.
- Diálogos de Abrir/Salvar usam as interfaces nativas do sistema quando possível.
- Configurações e preferências (por exemplo, config.json, language.json) são salvos localmente no caminho persistente do usuário (por exemplo, AppData).
- Nenhum dado é enviado automaticamente para servidores externos pelo aplicativo.
- Arquivos exportados (compactos, relatórios, etc.) são gravados no local escolhido pelo usuário.
- Adicione pastas/arquivos arrastando-os para a lista de entrada ou usando "Adicionar Pastas" / "Adicionar Arquivos".
- Especifique diretórios de saída para cada formato (botões "Especificar Saída" para .ZIP, .7Z, .TAR, .WIM e Extração).
- Selecione o método de compressão em Configurações → Selecionar Método de Compressão.
- Use "Armazenar" para iniciar a compressão no formato desejado.
- Marque múltiplas opções de formatos para exibir/ocultar layouts relacionados.
- Para testar integridade de arquivos compactados, selecione-os e execute "Testar Integridade".
- Para extrair, selecione arquivos compactados na lista de entrada e escolha um diretório de destino.
- 7‑Zip não encontrado: verifique se o 7zG.exe está instalado no sistema ou disponível dentro da pasta "7-Zip" do aplicativo. Mensagens de erro instrutivas serão exibidas.
- Erro ao gravar configurações: confirme permissões de escrita na pasta de usuário (AppData).
- Arquivos não extraem corretamente: verifique se o formato é suportado e se o 7‑Zip está funcional.
- Alto uso da CPU durante compressão: compressão em níveis altos (8–9) é intensiva; reduza o nível ou execute em momento apropriado.
- Suporte de formatos e comportamento dependem do executável 7‑Zip presente no sistema.
- Integração com PDFs/XLSX para importação/exportação (caso presente) requer conformidade de formato — use arquivos gerados por este aplicativo ou compatíveis.
- Componentes de terceiros seguem suas respectivas licenças; informações completas sobre licenças e avisos inclusos estão disponíveis na janela "Sobre" e nos arquivos de licença distribuídos com o instalador.

Compression Manager is a lightweight graphical utility for Windows designed for packing, extracting and integrity testing of files and folders. It supports multiple formats (ZIP, 7Z, TAR, WIM and other formats recognized by 7‑Zip), multiple output directories per format, configurable compression methods, a job queue and drag-and-drop operation. The interface is multilingual (pt_BR / en_US) and prepared for packaging as an executable (no manual Python dependency installation required for end users).
- Compress folders and files into .zip, .7z, .tar and .wim formats.
- Extract archives in many formats supported by 7‑Zip (.rar, .zip, .7z, .tar, .wim, .bz2, .tar.xz, .tgz, .tar.gz, .zipx, .lzh, .iso etc.).
- Maintain multiple output directories per format.
- Drag & drop to add files and folders to input/output lists.
- Configurable compression methods per format (levels 0–9 where applicable) and persistence of preferences.
- "Save as" mode to create packages with specific settings without changing global preferences.
- Update existing archives (option to update instead of recreating).
- Archive integrity test (7‑Zip "t" command) to validate packages.
- Job queue: new requests can wait while another task of the same format is running.
- Translatable messages and dialogs; runtime language switching.
- "About" window that loads description, history, licenses, notices and privacy policy from bundled resources.
- Offline operation: all data is local (config and preferences files stored in the user's persistent directory).
- GUI base: PySide6 (Qt) with custom widgets for multi-selection and drag-and-drop.
- Compression/extraction engine: 7‑Zip (7zG.exe). The app looks for a bundled 7‑Zip executable ("7-Zip" folder) or system locations (Program Files). If 7‑Zip isn't found, compression/extraction operations won't work and the user will be notified.
- Threads: compress, extract and test operations run in threads to keep the UI responsive.
- Persistence: compression methods and language preferences are saved in JSON files in the user's persistent directory (obter_caminho_persistente).
- Designed to be packaged as a Windows executable including resources and translations.
- When distributed as an installer/executable the end user does NOT need to install Python.
- Open/Save dialogs use native system dialogs when possible.
- Settings and preferences (e.g. config.json, language.json) are saved locally in the user's persistent path (e.g. %APPDATA% on Windows).
- No user data is sent automatically to external servers by the app.
- Exported files (archives, reports, etc.) are written to the location chosen by the user.
- Add folders/files by dragging them into the input list or using "Add Folders" / "Add Files".
- Specify output directories per format ("Specify Output" buttons for .ZIP, .7Z, .TAR, .WIM and Extraction).
- Choose compression method in Settings → Select Compression Method.
- Use "Store" to start compression in the desired format.
- Check multiple format options to show/hide related layouts.
- To test archive integrity, select them and run "Test Integrity".
- To extract, select archive files in the input list and choose a destination directory.
- 7‑Zip not found: verify 7zG.exe is installed or available inside the app's "7-Zip" folder. User-friendly error messages will be shown.
- Error writing settings: ensure write permissions for the user's folder (AppData).
- Archives not extracting correctly: verify the format is supported and 7‑Zip works.
- High CPU during compression: high compression levels (8–9) are CPU intensive; lower the level or run at a convenient time.
- Supported formats and behaviour depend on the 7‑Zip executable present on the system.
- Integration with PDFs/XLSX for import/export (if present) requires format compliance — use files produced by this app or compatible ones.
- Third-party components follow their respective licenses; full license and notices are available in the About window and license files bundled with the installer.
- Author: Fernando Nillsson Cidade
- For suggestions, bug reports and contributions, check the channels indicated in the installer or attached documentation.
This document describes the About dialog content and the app behaviour when distributed as a Windows executable. Advanced users interested in integration, automation or configuration storage locations should consult the included technical documentation or the source code for details.
