• 0 if the files have been extracted,
• An error code (value greater than 0) otherwise. For more details on these error codes, see the Remarks.

Name of a variable of type zipArchive corresponding to the archive to use.

Destination path of extracted files:

• Optional character string: files are extracted to the specified path plus the memorized tree structure for each file (the disk is not preserved). The specified path is created if it does not exist.
• Optional constant:
  

  zipDirectory	Extraction into the current directory while restoring the tree structure of file (if it was stored).
  zipDrive	Extraction: to the initial file location if it was stored and if the drive exists. while restoring the tree structure of the file on the current drive if the drive or the stored directory does not exist. into the current directory if only the file name and extension have been stored. Remark: If the constant zipDisk is used, the WDZ format memorizes the complete path of the file (including the drive letter), whereas the ZIP format memorizes only the drive letter.. Archives in format 7z: This constant will have the same effect as the constant zipDirectory.
  zipOverwrite	During the extraction, the existing read-only files are automatically overwritten by the extracted files. This constant can be combined with the zipDrive and zipDirectory constants.

Configure the extraction (if <Destination of files> corresponds to a character string):

zipOverwrite	During the extraction, the existing read-only files are automatically overwritten by the extracted files.

Name of the WLanguage procedure that will be called if an error occurs when extracting files.
WARNING: This parameter can only be used if the <Archive> parameter corresponds to a variable of type zipArchive.

This procedure has the following format:

PROCEDURE <Procedure name>(<Error code>, <File name>)

where:

• <Error code> is an integer corresponding to the code of the error that occurred when extracting the file.
• <File name> is a character string that contains the path of the file processed by <zipArchive variable>.ExtractAll.

The procedure can return one of the following constants:

zipCancel	Cancels the extraction of files from the archive.
zipIgnore	Ignores the file in error.
zipRetry	Retries the file extraction.

Progress bar management mode. This parameter can correspond to:

• the name of a WLanguage procedure. This procedure has the following format:
  
  PROCEDURE <Procedure name> (<Current file>,
  <Global progress percentage>, <File progress percentage>)
  
  where:
  • <Current file> corresponds to the name of the file currently processed.
  • <Global progress percentage> corresponds to the progress percentage of the extraction of files from the archive.
  • <File progress percentage> corresponds to the progress percentage of the file being extracted from the archive.

If you handle an:

• in gzip, TAR or TGZ (TAR.GZ)format, the ProgressBar is updated only at the end of extraction of each file..
• in CAB and RAR format, the progress bar is refreshed at the end of the extraction of each file.
• in 7z format, only <Overall progress percentage> is specified. <File progress percentage> will have the same value.
