Parameters
lcZipFile
File to zip to.
lcFileList
File or file list to zip up. This list can be space separated and each file entry can contain wildcards (*,?).
Files should be fully pathed and if filenames contain spaces use " to encapsulate them.
Example: ["c:\temp files*.bin" "c:\temp files*.xml"]
lnCompression
Compression efficiency 1 light, 9 max. Default 9.
llRecurseDirectories
Recurses filespecs through lower level directories and adds full path information. Note path information is not relative since DynaZip does not support this functionality (as Winzip does).
llAdditive
if .T. adds or overrides existing files in the zip files with the specified files.
Remarks
This is a library function, not a method of the wwAPI class.
Example
*** Create zip file with DBF and FPT files
ZipFiles("c:\temp\zipfiles.zip",CURDIR() + "*.dbf " + curdir() + "*.fpt")
*** Append additional files (last logical parm)
ZipFiles("c:\temp\zipfiles.zip",CURDIR() + "*.txt",9,.T.)
