After paying, the confirmation page shows your license key (it starts with FLOW-). If FlowUnzip is installed in that browser, Pro usually switches on automatically. Otherwise:

1. Right-click the FlowUnzip icon and choose Options.
2. Under Plan, paste the key and click Activate.

The same key works in every Chrome where you use FlowUnzip.

• FlowUnzip only handles .zip and .7z files. Others, like .rar or .7z.001 parts, download normally.
• The server has to report the file size up front. Some download scripts don't, so FlowUnzip leaves those alone.
• Downloads in Incognito windows are skipped.
• Check the settings page: "Offer to extract archive downloads" must be on, and the archive must be above the "Skip small archives" size.

FlowUnzip reads the archive in pieces, which needs the download server to support resumable downloads (HTTP range requests). Most large-file hosts do, but some don't. When a server doesn't, Chrome simply finishes the download as a normal file, and you can unzip it as usual.

• Password-protected ZIP and 7z archives
• 7z archives using PPMd, BZip2 or the BCJ2 filter (7-Zip picks BCJ2 for programs at maximum compression)
• Multi-part archives (.7z.001, .z01)
• 7z archives needing more than 1 GB of memory to decompress

In every one of these cases, FlowUnzip tells you why and the normal download continues.

FlowUnzip has no accounts, analytics or tracking. Archives are fetched directly from the site you're downloading from and written only to the folder you pick. See the privacy policy for details.
