| Scenario | Problem | ZIP Solution | |----------|---------|---------------| | Emailing a program | Email servers block .exe files | ZIP archives are often allowed | | Uploading to cloud storage (Dropbox, Drive) | Corporate policies block raw executables | Zipping bypasses basic content filters | | Downloading from a website | Browsers flag .exe as dangerous | ZIP files are seen as less threatening | | Reducing file size | Large executables take forever to transfer | ZIP compression shrinks the size | | Organizing multiple files | You have an .exe plus readme, DLLs, or docs | ZIP bundles everything together |
