TXT Compression Overview
Aspose.ZIP for .NET provides a fully managed C# API for compressing TXT documents in server-side and desktop applications. It supports batch operations, stream I/O, and configurable compression settings for predictable outputs. This fits document workflows that need repeatable packaging. Package TXT content into ZIP, 7Zip, TAR, GZIP, and other archives without external tools, and secure output with password protection or AES encryption when needed. This approach fits automation in batch jobs, CI pipelines, and server-side processing tasks.
How to Compress TXT File Using C#

The API then allows you to create archives, add files, and save the result with straightforward C# code. It works well for archiving document collections.
Command
PM> Install-Package Aspose.ZIP
Install Aspose.ZIP, create an Archive instance, add TXT files, and save the result. The steps below summarize the standard TXT compression flow in C#.
Steps to Compress TXT Files in C#
Developers can easily compress TXT files programmatically with just a few lines of C# code using Aspose.ZIP for .NET.
- Define the folder path that contains the TXT files.
- Create an instance of the
Archiveclass. - Using the
Archiveobject, load each file by its full path using theCreateEntrymethod. - Call the
Save()method and pass the output archive file name (full path) as a parameter. - The TXT files will be stored in a ZIP archive in the target folder without using any third-party zip, rar, or other compression tools.

C# Example: Create a ZIP Archive from TXT Files
The snippet below shows the core API steps to compress a TXT file: create an Archive object, add the entry, and save the resulting ZIP.
Compress TXT file via .NET:
var dir = "full directory path";
using (var arch = new Archive())
{
arch.CreateEntry("filename.txt", dir+"file.txt");
arch.Save(dir+"archived_result.zip");
}
FAQ
Can I compress multiple TXT files into a single ZIP archive using C#
1. Yes. Aspose.ZIP for .NET allows you to load and compress multiple TXT files by adding each file as an entry to the Archive object. You can combine individual files, folders, or streams into a single ZIP archive through a straightforward C# workflow.
Does Aspose.ZIP for .NET reduce the original quality of TXT files?
2. No. Aspose.ZIP performs lossless compression, meaning that the content and quality of your TXT files remain unchanged. The library only reduces file size by applying efficient archive compression algorithms without altering the actual data inside the file.
Can I password-protect ZIP archives that contain TXT files?
3. Yes. The library supports password protection and AES encryption, allowing you to securely package sensitive TXT files. You can specify encryption settings when creating entries or during the archive-generation process.
