## Save Options

- Archive format: A popup button which lets you choose the format you wish to use for saving. Depending on the format's capabilities you can choose whether to save the archive in multiple volumes and whether to use passwords encryption.
- Compression: For most formats you can choose the compression strength. Better compression always means slower operation.
- Encryption method: Some formats (7-zip, zip, rar) can be encrypted. Choose the encryption method from this pop-up button. If not absolutely necessary, don't use the weak zip encryption, because your data is not really safe then. Most of the time you will want to use Strong (AES-256) encryption. AES-256 is often called military-grade encryption strength, meaning there is no known way to break such an archive at this time. If you choose Strong (AES-256) encryption with header encryption, even the filenames will be encrypted and can't be listed without entering correct the password. Don't lose or forget your passwords, because no one will be able to help you then.
- Password: Click the Set button to enter your password. If you leave this field empty, BetterZip will ask you for a password when needed.
- Split into volumes of: To split the file into multiple volumes enter the size of the resulting files in the text field and choose a unit (KB, MB, GB) from the popup button. If you don't want to split your archive, leave the text field blank.
- Additional parameters: Some formats can be tweaked with more options. You can enter them here, but make sure you know what you are doing.
- Run script when done: After the archive creation, BetterZip will execute this shell script or command, passing in the archive's filename.
- Remove Mac specific stuff from archives: BetterZip can also remove Mac specific files and folders from the archive. A zip file created on a Mac usually contains a lot of hidden files and folders that only other Macs understand, e.g., Finder settings and resource forks. For a Windows or Linux user these files are just garbage.
- Clean the archive before saving.
- Set the archive's date to the latest date in the archive: Does exactly that. If you create an archive of a file dated November 8th 2004 the archive's date will normally be today's date. If you set this option, the archive's date will be November 8th 2004.
