function Compress-WinRAR(){ <# .SYNOPSIS Compress the specified directory into the specified .rar archive .DESCRIPTION Compress the specified directory into the specified .rar archive .PARAMETER DirectoryToCompress Directory which will be compressed into the Archive .PARAMETER ArchivePath Path to .rar file into which the directory will be compressed .PARAMETER CompressionLevel Level of compression. Higher values use more compute power and will possibly result in lower archive size. Permitted Values 0-5 .PARAMETER DictionarySize Size of dictionary to use while compressing. A bigger dictionary results in higher RAM usage and possibly lower archive size. Permitted values are 1-1024 .PARAMETER DictionarySizeUnit Unit for parameter DictionarySize. Possible values are 'k', 'm' and 'g' for kilobytes, megabytes and gigabytes respectively .PARAMETER Threads Number of Threads to use for compression. Permitted values are 1 up to the number of threads of the system .PARAMETER Password Password to be set for the .rar file .PARAMETER ErrorLogFile Path to file where errors will be logged .PARAMETER FileMask Filter files to include .PARAMETER RecoveryPercentage Percentage of archive size that will be dedicated to recovery data .PARAMETER Delete Delete original directory after compression .PARAMETER SafeDelete Move original directory to recycle bin after compression .PARAMETER IgnoreEmptyDirectories Ignore empty directories in the source directory and not adding them to the archive .PARAMETER Recurse Recurse the source directory .PARAMETER SolidArchive Create a solid archive. Results in smaller size but slower read/modify speeds for the archive .PARAMETER TestArchive Test the archive after creation .PARAMETER StructureInArchive Set the directory structure in the Archive. # 'Flat' moves all files into the root of the archive. # 'Relative' moves all files into the archive with their relative paths to the root directory into the archive # 'Full' includes the full path of every file in the archive # 'DriveLetter' acts like 'Full' but also includes the drive letter .PARAMETER UseRAR4 Use older RAR4 compression method instead of RAR5 .PARAMETER PassThruParameters This string gets passed through to the winrar command line tools .INPUTS Pipeline inputs get used as DirectoryToCompress .OUTPUTS Returns the archive Path .EXAMPLE Compress-WinRAR ./Directory/
