Extract Method

Extracts a single file, directory, or group of files, from the archive.

Syntax

async sevenzip.extract(filenames : string): Promise<void>

Remarks

Extract extracts one or more files from the archive. The file(s) will be extracted to the directory specified by ExtractToPath, and given the names found in the archive or specified by the FilesDecompressedName of the file in the Files collection.

Filenames may be set to one or more filenames or directory names. Files may be specified with or without a path, and with or without wildcards. If a path is specified, files in the indicated directory will be affected; subdirectories will be recursed into if RecurseSubdirectories is true. If no path is specified but wildcards are, matching files in all directories will be affected. If a single filename without a path is specified, it must correspond exactly to the appropriate value of FilesCompressedName.

Directories should end with a slash ("/"). If a directory is specified, all files and subdirectories in the specified directory will be affected.

A pipe character ("|") should be used to separate multiple file or directory names. Alternatively, the method may be invoked repeatedly.

The ExcludedFiles property may be used to further limit the files to be extracted. When Extract is used to extract a directory or match wildcards, each file to be extracted is first compared against ExcludedFiles, and any files marked as excluded will not be extracted. When Extract is used to extract a single file, the value of ExcludedFiles will be ignored.

To extract all files in the archive, the ExtractAll method may be used.

The BeginFile and EndFile events will be fired before and after each file is extracted, and the Progress event will be fired as the data is extracted. If WriteToProgressEvent is set to true, the decompressed data will be streamed out through the Progress event.

Example


ZipControl.ArchiveFile = "c:\test.tar"
ZipControl.ExcludedFiles = "*.bak | backup/"
ZipControl.ExtractToPath = "c:\temp"
ZipControl.Extract("*")
Example
ZipControl.ArchiveFile = "c:\test.zip"
ZipControl.ExcludedFiles = ""
ZipControl.ExtractToPath = "c:\temp"
ZipControl.Extract("code/")
Example
ZipControl.ArchiveFile = "c:\test.jar"
ZipControl.ExcludedFiles = "*.txt"
ZipControl.ExtractToPath = "c:\"
ZipControl.Extract("* | docs/readme.txt")
