This release adds a new \u201csplit into a number of files\u201d mode, delivers faster splitting performance, and fixes a crash when splitting UTF-16 files.<\/p>\n<h2>What\u2019s New in BigTextFileSplitter 4.3<\/h2>\n<h3>1. Split into N Files (by File Size or by Line Count)<\/h3>\n<p>Until now, you told BigTextFileSplitter <em>how big<\/em> each output file should be \u2014 for example \u201c10 MB per file\u201d \u2014 and the tool decided how many files to create. Version 4.3 flips that around: just tell it <strong>how many files you want<\/strong> (N files), and it works out the rest.<\/p>\n<p>You can split into N files in two ways:<\/p>\n<ul>\n<li><strong>By file size<\/strong> \u2014 the output is split into N files of roughly equal size.<\/li>\n<li><strong>By line count<\/strong> \u2014 each output file gets a balanced number of lines, so no file ends up much larger than the others.<\/li>\n<\/ul>\n<p>For example, split a 50 GB log into 10 files of about 5 GB each, or split a huge CSV into 20 files with an equal number of rows. This is handy when a platform limits upload size, when you want to process the same data in parallel, or when you need to hand a large file out to several people.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.withdata.com\/images\/bigtextfilesplitter\/split-csv-by-file-count.png\" alt=\"Split a large CSV file into a fixed number of files (N files) by file size or by line count\" width=\"964\" height=\"673\" style=\"max-width:100%; height:auto; display:block;\" \/><\/p>\n<h3>2. Faster Splitting Performance<\/h3>\n<p>The splitting engine has been optimized further, so large text files are processed faster while memory usage stays low. The improvement is most noticeable on multi-gigabyte TXT, CSV, LOG and JSON files, and it applies to every split mode \u2014 not only the new \u201cinto N files\u201d mode.<\/p>\n<h3>3. Fixed a Crash When Splitting UTF-16 Files<\/h3>\n<p>Version 4.3 fixes a crash that could occur when splitting UTF-16 encoded files. UTF-16 text is common in Windows environments and in files exported by some tools, and it is now handled correctly, so the split output keeps the original encoding intact.<\/p>\n<h2>About BigTextFileSplitter<\/h2>\n<p><a href=\"https:\/\/www.withdata.com\/big-text-file-splitter\/\">BigTextFileSplitter<\/a> splits huge text files into smaller, easy-to-handle files \u2014 fast, locally, and without coding.<\/p>\n<ul>\n<li>Split by line count, by file size (KB\/MB\/GB), by keywords\/strings, by symbol, or into a fixed number of files (N files)<\/li>\n<li>Works with TXT, CSV, TSV, LOG, JSON, JSONL, XML and other text-based files<\/li>\n<li>Handles GB-level files with low memory usage and no practical file size limit<\/li>\n<li>Preserves the original encoding and format (including UTF-8 and UTF-16)<\/li>\n<li>Batch splitting, saved sessions, and command-line support for automation<\/li>\n<li>Cross-platform: Windows, Linux, macOS<\/li>\n<li>Fully local offline processing; no data uploaded to cloud servers<\/li>\n<\/ul>\n<h2>Upgrade Today<\/h2>\n<p><a href=\"https:\/\/www.withdata.com\/big-text-file-splitter\/\">BigTextFileSplitter 4.3<\/a> is ready for download: <a href=\"https:\/\/www.withdata.com\/big-text-file-splitter\/download.html\">https:\/\/www.withdata.com\/big-text-file-splitter\/download.html<\/a>.
