Vovsoft File Splitter And Joiner: Cut a Big File Down to Size
File Splitter And Joiner is a $19 Windows program from Vovsoft that splits a large file into numbered parts of a size you pick, then joins them back together. The $19 is a one-time lifetime license, and there's a free trial.
It's the classic fix for a 10 GB file that won't fit on a FAT32 stick. It's also a job free tools have done for decades.

Overview
On the Split File page, pick the large file, an output folder and a maximum part size, then press Split Now. On the Join Files page, select the parts and the program rebuilds the original.
Features
Parts sized to the destination
File Splitter And Joiner takes a maximum part size in bytes, with one-click presets, so you can match a FAT32 limit, a disc or an upload cap.
One program for both directions
File Splitter And Joiner splits and rejoins, and joining the series takes one click once you've selected the files.
Long path support
File Splitter And Joiner handles path and file names longer than 260 characters.
Who It's For, and Who Should Skip It
It suits someone moving very large files through a size limit, who wants plain numbered parts and no archive format.
Skip it if you have 7-Zip: the free archiver can split any file into volumes as it compresses. Windows can also rejoin plain numbered parts by itself with the copy /b command, so the recipient doesn't have to buy this.
Usage Guide
- Download the installer or the portable edition and start the program.
- Open Split File and load the large file.
- Choose an output folder and a maximum part size.
- Press Split Now.
- To rebuild, open Join Files, select the parts and join them.
Before you buy
One license covers one person on as many of their own computers as they use, or one shared workstation used by several people in turn. Using a key on too many computers at the same time can get it revoked.
Where it falls short
- It doesn't compress the parts, so together they take as much space as the original.
- It can't make a self-extracting file, which is an open request, so whoever receives the parts needs a way to join them.
- It splits by bytes only. Splitting PDF or TIFF files by page is an open request.
- The last release was May 2024.

Conclusion
Hard to justify at $19 unless you want a dedicated window for this. The reason to buy it is plain splitting with long-path support. The main reason not to is that 7-Zip does the job free.
