WM5 file compress/uncompress

Hi.

We are transferring files to & from PDA's (windows mobile 5) over
GPRS and want to compress the files. What is the best method supported
by WM5?

We are developing applications using VS2005 & VB.NET v2 on a server and
VB.NET CF V2 on WM5. our applications are receiving data which needs
compressing and uncompressing automatically.

I use the ZIP classes from Resco.

The XCeed Streaming compression library is also worth a look:

I use zlib compression. Decompression can use up a fair bit of memory,
so I decompress the XML data to a temp file on the SD Card to avoid
"out of memory" issues.

Hi,

I've been using the XCeed compression library to download a large
DataSet - serialized as XML.

Decompression uses quite a lot of memory, so I decompress to the SD
Card - then read in a bit at a time.
