Zenc Utility Information


Zenc Command Line Utility

"Zenc" is a Windows command line (DOS prompt) utility. It allows you to compress, encrypt, decompress or decrypt files in the same way that SyncShell does.

Basic Parameters

The basic usage of Zenc is "zenc [/p:password /c /d] inputFile".

Zenc recognizes the SyncShell extensions of .zenc, .zpenc and .zpzenc and will create a normal (unencrypted and uncompressed) file from an input file with one of these extensions.  It will also reverse compression and encryption to recreate a normal file from an encrypted and/or compressed file.

If you give Zenc a file name with a special SyncShell extension, it will automatically perform decompression and decryption as necessary, based on the extension.

The options of Zenc are:

  • /p:Password    This option is used to specify a password for encryption or decryption. If this option is used to process a normal input file, the output will automatically be encrypted.
  • /c   This option is used to specify that a normal input file is to be compressed.
  • /d    This option is used to delete the input file when Zenc exits.

The Zenc utility is provided for use when you need to perform an operation on a single file contained within a SyncShell folder.

Getting Zenc

The Zenc utility is installed in the same directory as SyncShell.exe. You can put that directory on your path to make it easier to use Zenc. 

You cannot merely copy ZENC.EXE to another folder because it uses many of the same libraries (assemblies) as SyncShell and expects to find them in the same directory in which it resides.
