HJSplit

Ever needed to send a massive file but ran into size limits? HJSplit is here to rescue you a totally free, no installation required tool that lets you split and reassemble files as huge as 100+ gigabytes. It’s lightweight, straightforward, and packed with four handy features: Split, Join, Compare, and Checksum.

With the Split function, you get to decide how big or small you want your file parts to be. You can choose sizes ranging from kilobytes all the way up to gigabytes. This makes it super easy to fit pieces onto floppy disks (if you're feeling nostalgic!), CDs, DVDs, USB drives, or even email attachments. No more struggling with upload restrictions or storage limits.

Once you’ve sent those split files, the Join feature puts everything back together seamlessly, recreating the original file exactly as it was bit for bit. Worried about file integrity? The Compare tool checks two files to confirm they’re identical in both size and content. And for an extra layer of security, the Checksum function generates an MD5 hash. Share this with your recipient to verify that the files haven’t been tampered with or corrupted during transfer.

One of the coolest things about HJSplit is its portability. It runs directly from a single tiny executable no messy installs, no registry changes. Plus, it’s cross platform friendly. There are even legacy versions available for Windows 3.x and MS DOS, meaning you can split a file on an old machine and reassemble it on a modern Windows system without a hitch. Simple, reliable, and timeless HJSplit remains a trusted solution for handling large files across generations of technology.
