    "Html": "<p>The ZipFile class, on which the SaveProgress event hangs,&nbsp;in the general case, does not &quot;know&quot; the size of any entry (either compressed or uncompressed) until the entry is saved.&nbsp;&nbsp; Sometimes, maybe most of the time, the entry is sourced from a filesystem file, in which case it would be easy to determine the length of the file.&nbsp;&nbsp; Sometimes though, the entry comes from a stream, and the length of the stream is not known, and cannot be known, until it is read.&nbsp; So there is no general, correct way for the ZipFile class to &quot;know&quot;, before the Save completes, how many bytes will be read and compressed as part of the Save.&nbsp; Do you see?&nbsp;&nbsp; &nbsp;</p>\r\n<p>If you have the situation where all of the entries in your ZipFile are filesystem files, then YES, you can keep track of that yourself and update a progress bar with that information.&nbsp; But ZipFile does not do that for you.</p>\r\n<p>I can imagine a modification to&nbsp;ZipFile where it provides what you want, if all of the entries are filesystem files. That would be convenient, I imagine.&nbsp; But today it does not do that.</p>\r\n<p>&nbsp;</p>",
