I am using following code to zip a file and it works fine but when I decompress with WinRar I get the original file name without the extension, any clue why if filename is myReport.xls
when I decompress I get only myReport
?
using (var fs = new FileStream(fileName, FileMode.Open))
{
byte[] input = new byte[fs.Length];
fs.Read(input, 0, input.Length);
fs.Close();
using (var fsOutput = new FileStream(zipName, FileMode.Create, FileAccess.Write))
using(var zip = new GZipStream(fsOutput, CompressionMode.Compress))
{
zip.Write(input, 0, input.Length);
zip.Close();
fsOutput.Close();
}
}
GZip compresses only one file - without knowing the name. Therefore if you compress the file myReport.xls
you should name it myReport.xls.gz
. On decompression the last file extension will be removed so you end up with the original filename.
That its the way how it is used in Unix/Linux for ages...
