How to Create a Split Archive on Mac
Short answer: You can create a split archive on Mac with ZipGood by choosing 7z or ZIP as the output format and configuring split volumes in the format options panel. ZipGood writes the archive as several numbered volumes.
Why split an archive?
Email attachments, upload forms and some servers impose a maximum file size. Splitting a large archive into several smaller volumes lets you send or upload it in parts without reducing the amount of data.
How to create split volumes with ZipGood
- Install ZipGood from the Mac App Store.
- Drag the files you want to archive onto the ZipGood window.
- Select 7z or ZIP as the output format.
- Enable split volumes and set the volume size in the options panel.
- Click Compress — ZipGood writes the numbered volumes.
Supported split formats
- 7z — produces volumes named .7z.001, .7z.002, and so on
- ZIP — produces volumes named .z01, .z02, and so on
- Both formats are joined automatically by ZipGood when extracting
Frequently Asked Questions
Which formats can ZipGood split into volumes?
ZipGood can create split volumes for 7z and ZIP archives. Other output formats such as TAR, GZIP, DMG and ISO do not support split-volume creation.
How do I open a split archive later?
Keep all the volumes in the same folder and open the first one. ZipGood joins the parts automatically — see How to Extract a Split Archive.
Does splitting reduce the compression ratio?
Splitting an archive into volumes does not remove data; it only divides the archive into parts. The compression settings you chose still apply.
