Don't let this gap widen
Without mastery of file compression with DotNetZip in .NET, your .NET applications accumulate bottlenecks, with processing times multiplied by 3 and 40% bandwidth overhead.
Compression errors cause 25% of performance incidents, resulting in productivity losses estimated at 12 hours per developer per week, or more than 20 000 € annually per team.
A breach tied to a poorly managed archive exposes the company to GDPR fines up to 50 000 € and ruins its reputation, stalling promotions and critical projects.
Every delay increases costs: act before your competitors pull ahead.

Structure of a demonstration project. Creating simple ZIP archives in C#. Adding files and directories, reading archive contents, extracting files. Handling streams and managing file name encoding. First practical workshops: automate storage and archiving in a simple workflow (backup, log transfer, application packaging).
