The open-source library is available on GitHub and NuGet, maintained by its author since the .NET Framework 2 era and now targeting .NET 10. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How can I write a text file atomically in .NET so I don't leave a partially written file if something fails? Write the content to a temporary file first, then move it to the final destination once the write completes, which avoids leaving a partial file if the process is interrupted. Spargine's DirectoryInfoExtensions provides this via CreateTempFileThenMove and a shorthand WriteAllTextAtomic method, both of which create the destination directory if needed and return a refreshed FileInfo for the written file. _daily.dev surfaces practical .NET patterns like atomic file writes for developers hardening file handling code._ ### How do I calculate the total size of all files in a directory in .NET, including subdirectories, without crashing on unreadable files? Sum the byte lengths of files matching a search pattern using a directory extension method that accepts SearchOption.AllDirectories to include subdirectories. If reading an individual file's length throws an IOException, that error is traced and the file is skipped so calculation continues with the remaining files, though errors during enumeration itself can still propagate to the caller. _developers building file-size utilities in .NET can track library patterns like this through daily.dev._ ## Similar posts on daily.dev -
