To convert characters used to mark line endings in ASCII text files to conform to the conventions of a different platform:

Select the style of line ending you want from the End of line drop-down menu:


None - no conversion

The default. In general, use this setting when extracting files to use on Windows from an archive created on Windows.

DOS/Windows - CR/LF

Substitute the line endings used on DOS and Windows

Mac - CR

Substitute the line endings used on the "classic" Macintosh operating system

Unix - LF

Substitute the line endings used on the UNIX, Linux or Mac OS X operating system


Substitute NL line endings.*

EBCDIC (Extended Binary Coded Decimal Interchange Code) is an older character encoding still used on many IBM mainframe and minicomputer operating systems. Different versions use different line endings.


Substitute LF line endings*


Substitute CRLF line endings*


Substitute LFCR line endings*


Substitute CRNL line endings*

*This option is for use with data compressed using PKZIP/SecureZIP/Smartcrypt for z/OS or PKZIP/SecureZIP/Smartcrypt for IBM i with the Zip Descriptor Word (ZDW) option to preserve variable length records.

Note: Different platforms use different characters to mark line endings in ASCII text files (.txt, .htm, and other kinds of files that are not binary files). If the line endings for an ASCII file are wrong for your system, it can affect the display and printing of the file.

Smartcrypt substitutes the specified line endings only for files internally flagged as ASCII files in the archive. Smartcrypt flags ASCII files as such when adding them to an archive, but other compression programs may not. As a result, if the archive was not created using Smartcrypt, it is possible that line endings for ASCII files in the archive will not be converted as specified.

To convert the case of file names when extracting:

Select from the File name case drop-down menu how you want to convert the case of file names:

  • No conversion

  • Convert to lower case

  • Convert to upper case

Note: You can only convert case for files that do not already exist in the target folder. Windows does not change the case of file names when updating existing files unless the files are actually renamed.

To restore the file dates saved with files when they were archived: Check the box for each type of date that you want to restore—Modification date, Creation date, Access date. All the boxes are checked by default.

Note: Files are extracted using the current date and time if Modification date is not checked.

To restore file attribute settings saved with files when they were archived: Check the box in the Restore file attributes group for each attribute for which you want to restore settings.

To restore alternate data stream information with files when they were archived, select from the Restore Alternate Streams drop-down menu:



Do not restore any alternate data streams.


Restore only NTFS (Windows) alternate streams.


Restore any recognized alternate data streams. (Note: Macintosh resource forks will restore as named files.)

Zone Identifiers are an alternate data stream created by Microsoft Internet Explorer to define "security zones" for downloaded data. These zones are labeled Local Intranet, Trusted Sites, Internet, and Restricted Sites. Check the Copy Zone Identifier box to include this information when you extract downloaded files.
