(VBScript) Deflate FileDemonstrates how to use the Deflate compression algorithm to compress a file. (The deflate compression algorithm is the most commonly used in the Zip archive file format.) This code is capable of compressing any size file because the file data is compressed from input to output in a streaming mode. The output file contains only the deflated data (it is not a .zip, and there is no file structure or format).
Dim fso, outFile Set fso = CreateObject("Scripting.FileSystemObject") Set outFile = fso.CreateTextFile("output.txt", True) set compress = CreateObject("Chilkat.Compression") ' Any string argument automatically begins a 30-day trial. success = compress.UnlockComponent("30-day trial") If (success <> 1) Then outFile.WriteLine(compress.LastErrorText) WScript.Quit End If compress.Algorithm = "deflate" ' Deflate this XML file: success = compress.CompressFile("hamlet.xml","hamletDeflate.dat") If (success <> 1) Then outFile.WriteLine(compress.LastErrorText) WScript.Quit End If ' Inflate back to the original: success = compress.DecompressFile("hamletDeflate.dat","hamletInflated.xml") If (success <> 1) Then outFile.WriteLine(compress.LastErrorText) WScript.Quit End If outFile.WriteLine("Success!") outFile.Close |
