Compresses the source file using a variety of supported compression algorithms . This method will create a destination file in the destination directory and will append a file extension matching the compression algorithm used . For example using gzip will mean a source file of app . log would be compressed to app . log . gz and placed in the destination directory .

public static File uncompress ( File sourceFile , boolean deleteSourceFileAfterUncompressed ) throws FileAlreadyExistsException , IOException { return uncompress ( sourceFile , sourceFile . getParentFile ( ) , deleteSourceFileAfterUncompressed ) ; }
|
Uncompresses the source file using a variety of supported compression algorithms . This method will create a file in the same directory as the source file by stripping the compression algorithm s file extension from the source filename . For example using gzip will mean a source file of app . log . gz would be uncompressed to app . log .
