Common questions

How does the recipient open a Secure share zip?

On a Mac: double-click the zip and type the password. On Windows: open it with 7-Zip (free, 7-zip.org). The zip tool in Windows cannot open zips with AES-256 encryption.

I lost the password. Can you open the zip?

No. Zipseal does not keep passwords, and nobody can open an AES-256 zip without the password. Make a new Secure share from the original files.

Are the file names in the zip secret too?

No. A zip with a password encrypts the contents of the files, not the file names. If a name is private, change it before you share, or put the files in a folder with a neutral name.

Why does Zipseal ask for access to a folder?

macOS lets an App Store app write only where you allow it. Zipseal asks one time for each folder, so that it can save the zip or the extracted files next to your files. You can see and remove the folders in Zipseal > Settings > Folders.

I do not see "Secure Share with Zipseal" in Finder.

Open System Settings > General > Login Items & Extensions, then turn on Zipseal in the Finder extensions. In Finder, right-click the files and choose Quick Actions.

How do I open zip files with Zipseal by default?

Choose Zipseal > Make Zipseal the Default App. macOS asks you to confirm. You can also select a zip in Finder, choose File > Get Info, select Zipseal under "Open with", and click "Change All".

The recipient has a zip in parts (.zip.001, .zip.002). How do they open it?

Save all parts in one folder. On Windows, open the .001 file with 7-Zip. On a Mac, open it with Zipseal, 7-Zip, or Keka. Archive Utility cannot open parts.

Zipseal says that an archive expands to a very large size.

Some damaged or harmful archives expand to a very large size and can fill your disk. If you trust the archive and have the space, click "Extract Anyway".
