Copy Mode User-Defined

The following options are available when using the copy mode user-defined:

Save all source files at the destination folder without their folder structure
Store source file as compressed ZIP file at destination

Save all source files at the destination folder without their folder structure

This causes all source files to be saved at the destination folder without their folder structure. For example, the source file C:\Data\Office\info.txt will be copied to the destination folder D:\Data\ and NOT into the subfolder D:\Data\Office\.

Store source file as compressed ZIP file at destination

This causes a source file being copied to be stored as a compressed ZIP file at the destination.
Example: Data.doc -> Data.doc.zip

Compression

This option enables you to specify the compression to be used for the files being backed up. The following compression levels are available:

None
Fast
Normal (default setting)
Maximum

The higher the compression, the longer it takes for the ZIP file to be created. The None option causes items to be zipped without being compressed.

Compression method

The following compression methods are available:

Deflate is the default compression method of the general ZIP format supported by many other programs. In comparison to Deflate, Deflate64 and BWT enable a higher degree of compression to be achieved, however, they aren't supported by all programs.

Encryption

This option enables you to password-protect the ZIP file against unauthorized access. The following encryption methods are available:

Standard Zip 2.0
AES 256-bit

Using the AES encryption method is advisable as it provides a much higher degree of security than conventional Zip 2.0 encryption.
