Removing directory inforamtion from zipped file

Apr 29, 2008 at 5:31 AM
I am using this excellent code to zip a file, which is then uploaded to a server and upzipped on the server. I am having problems in that the zipped file seems to carry the path information with it, and unattended unzipping in a totally different environment does not work.

The code for zipping is

//compress (zip) the file to speed transfer
//don't foget to unzip on site
//also store on site in zip format for archive
Ionic.Utils.Zip.ZipFile zfile = new ZipFile("");

and the code on the server (WS2003) is

protected void Page_Load(object sender, EventArgs e)
string appath = Request.PhysicalApplicationPath;
Ionic.Utils.Zip.ZipFile zfile = new ZipFile(appath + "/data/");
//unzip the file
zfile.Extract( appath + "/data/Data.mdb");

Any help in making this work would be greatly appreciated
Many Thanks

There is an override method that allows you to specify the directory path for entries as you add them to the ZipFile.
Check the doc!

AddFile(Filename, DirectoryInArchive);

if you want the entry to be in the top-level dir in the archive, do this: 
AddFile(Filename, "");
