Compression or containing Multiple files

[Guest]

Hi,

Does .NET have classes or in the near future have classes to allow me to
compress N files into one or somehow contain N files in one (even without
compression)?

If .NET hasnt or wont, does the platform at all have any I can PInvoke?

Hi,

Take a look at this article:

Using the Zip Classes in the J# Class Libraries to Compress Files and Data
with C#
MSDN Magazine, June 2003

That unfortunately requires my dependancy on yet another runtime (J#)

WIndows XP has built in compressed folders, I would assume its just a matter
of PInvoke on that library, but thats XP specific, I cant see any
Compression classes in the Longhorn or next up and comming .NET API set.

Since they have a license for XP and I assume LH for compression, why not
make it available in the Libraries?

The only other option is to use XML either as a manafest or as a container
with binary chunks.

What about using alternate streams? NTFS files have the ability to have
multiple streams. The only downside is if you need to copy the file to a
FAT/FAT32 partition, only the primary stream will be copied.

Check out Xceed's Zip compression managed library...

I beta tested it a while back, it worked great... they implemented the
compression as streams so you can compress/decompress anything... net
socket, filestream, memory bytes etc..

XCeed has a Zip Compression assembly that you can use to create and
manipulate compressed files
