Controlling filepaths within a Zip

How to control the filepaths stored within a .zip.

LOCAL loZip
LOCAL lnSuccess
LOCAL lnRecurse

loZip = CreateObject('Chilkat.Zip2')

*  Any string unlocks the component for the 1st 30-days.
lnSuccess = loZip.UnlockComponent("Anything for 30-day trial")
IF (lnSuccess <> 1) THEN
    =MESSAGEBOX(loZip.LastErrorText)
    QUIT
ENDIF

*  This is the directory structure on the local filesystem
*  from which we'll create .zip archives:
*  The root directory is c:\temp\filesToZip
* 
*  We have these files:
*  c:\temp\filesToZip\faxCover.doc
*  c:\temp\filesToZip\exe\Setup.exe
*  c:\temp\filesToZip\images\cheese.jpg
*  c:\temp\filesToZip\images\dude.gif
*  c:\temp\filesToZip\images\img3.gif
*  c:\temp\filesToZip\images\img4.gif
*  c:\temp\filesToZip\images\img5.gif
*  c:\temp\filesToZip\images\scream.jpg
*  c:\temp\filesToZip\images\imageInfo\scream.xml
*  c:\temp\filesToZip\images\imageInfo\cheese.xml
*  c:\temp\filesToZip\text\html\bonaireFishing.html
*  c:\temp\filesToZip\text\html\upload.html
*  c:\temp\filesToZip\text\txt\hello.txt
*  c:\temp\filesToZip\text\txt\HelloWorld123.txt
*  c:\temp\filesToZip\text\xml\hamlet.xml
*  c:\temp\filesToZip\text\xml\pigs.xml

*  There are three properties to help control the paths stored
*  within a .zip:
*  AppendFromDir
*  PathPrefix
*  DiscardPaths
* 

*  First we'll demonstrate AppendFromDir
*  When a directory tree is appended via AppendFiles or
*  AppendFilesEx, the AppendFromDir sets the base of the
*  directory tree appended (if the file pattern contains a
*  relative path, or no path at all).

*  Clear the zip object.
loZip.NewZip("test1.zip")

lnRecurse = 1

loZip.AppendFromDir = "c:/temp/filesToZip"
loZip.AppendFiles("*.xml",lnRecurse)

*  The zip will contain:
*  images\imageInfo\scream.xml
*  images\imageInfo\cheese.xml
*  text\xml\hamlet.xml
*  text\xml\pigs.xml

lnSuccess = loZip.WriteZipAndClose()
IF (lnSuccess <> 1) THEN
    =MESSAGEBOX(loZip.LastErrorText)
    QUIT
ENDIF

*  Clear the zip object.
loZip.NewZip("test2.zip")

loZip.AppendFromDir = "c:/temp/filesToZip/images"
loZip.AppendFiles("*.xml",lnRecurse)
loZip.AppendFromDir = "c:/temp/filesToZip/text"
loZip.AppendFiles("*.xml",lnRecurse)

*  The zip will contain:
*  imageInfo\scream.xml
*  imageInfo\cheese.xml
*  xml\hamlet.xml
*  xml\pigs.xml

lnSuccess = loZip.WriteZipAndClose()
IF (lnSuccess <> 1) THEN
    =MESSAGEBOX(loZip.LastErrorText)
    QUIT
ENDIF

*  The PathPrefix property adds an arbitrary path prefix to each
*  file in the .zip.
*  For example:

*  Clear the zip object.
loZip.NewZip("test3.zip")

loZip.PathPrefix = "chilkat/"

loZip.AppendFromDir = "c:/temp/filesToZip/images"
loZip.AppendFiles("*.xml",lnRecurse)
loZip.AppendFromDir = "c:/temp/filesToZip/text"
loZip.AppendFiles("*.xml",lnRecurse)

*  The zip will contain:
*  chilkat\imageInfo\scream.xml
*  chilkat\imageInfo\cheese.xml
*  chilkat\xml\hamlet.xml
*  chilkat\xml\pigs.xml

lnSuccess = loZip.WriteZipAndClose()
IF (lnSuccess <> 1) THEN
    =MESSAGEBOX(loZip.LastErrorText)
    QUIT
ENDIF

*  The DiscardPaths property removes the path from each file
*  in the zip:
*  For example:

*  Clear the zip object.
loZip.NewZip("test4.zip")

loZip.PathPrefix = ""
loZip.DiscardPaths = 1

loZip.AppendFromDir = "c:/temp/filesToZip/"
loZip.AppendFiles("*",lnRecurse)

*  The zip will contain:
*  faxCover.doc
*  Setup.exe
*  cheese.jpg
*  dude.gif
*  img3.gif
*  img4.gif
*  img5.gif
*  scream.jpg
*  scream.xml
*  cheese.xml
*  bonaireFishing.html
*  upload.html
*  hello.txt
*  HelloWorld123.txt
*  hamlet.xml
*  pigs.xml

lnSuccess = loZip.WriteZipAndClose()
IF (lnSuccess <> 1) THEN
    =MESSAGEBOX(loZip.LastErrorText)
    QUIT
ENDIF

*  You can combine PathPrefix with DiscardPaths:

*  Clear the zip object.
loZip.NewZip("test5.zip")

loZip.PathPrefix = "chilkat/"
loZip.DiscardPaths = 1

loZip.AppendFromDir = "c:/temp/filesToZip/"
loZip.AppendFiles("*",lnRecurse)

*  The zip will contain:
*  chilkat\faxCover.doc
*  chilkat\Setup.exe
*  chilkat\cheese.jpg
*  chilkat\dude.gif
*  chilkat\img3.gif
*  chilkat\img4.gif
*  chilkat\img5.gif
*  chilkat\scream.jpg
*  chilkat\scream.xml
*  chilkat\cheese.xml
*  chilkat\bonaireFishing.html
*  chilkat\upload.html
*  chilkat\hello.txt
*  chilkat\HelloWorld123.txt
*  chilkat\hamlet.xml
*  chilkat\pigs.xml

lnSuccess = loZip.WriteZipAndClose()
IF (lnSuccess <> 1) THEN
    =MESSAGEBOX(loZip.LastErrorText)
    QUIT
ENDIF

*  One last example -- combine DiscardPaths with PathPrefix
*  with multiple calls to AppendFiles:

*  Clear the zip object.
loZip.NewZip("test6.zip")

loZip.DiscardPaths = 1
loZip.AppendFromDir = "c:/temp/filesToZip/"

*  Get all .gif files:
loZip.PathPrefix = "gif/"
loZip.AppendFiles("*.gif",lnRecurse)

*  Get all .jpg files:
loZip.PathPrefix = "jpg/"
loZip.AppendFiles("*.jpg",lnRecurse)

*  Get all .xml files:
loZip.PathPrefix = "xml/"
loZip.AppendFiles("*.xml",lnRecurse)

*  The zip will contain:
*  jpg\cheese.jpg
*  gif\dude.gif
*  gif\img3.gif
*  gif\img4.gif
*  gif\img5.gif
*  jpg\scream.jpg
*  xml\scream.xml
*  xml\cheese.xml
*  xml\hamlet.xml
*  xml\pigs.xml

lnSuccess = loZip.WriteZipAndClose()
IF (lnSuccess <> 1) THEN
    =MESSAGEBOX(loZip.LastErrorText)
    QUIT
