>>>>> If you ordered the registered version of TCompress, see REGINFO.TXT

These components are fully functional SHAREWARE.

If you find TCompress useful, registration will get you the
latest version, a personal ID to eliminate the occasional
reminder message, access to our highly regarded (and, I have
to say it, rarely needed) support AND a nice warm
fuzzy feeling.

Registration details are at the end of this file.

1. Key features:

* Standard support for Delphi 1.0, 2.0, 3.0 and C++ Builder
* NATIVE compression -- no mucking about with DLLs, OCXes et al
* Multi-file compressed archives using the TCompress component
* Database BLOB (memo, image) compression with TCDBMemo,
  TCDBimage and (for Delphi 3.0 only) TCDBRichText
* In-memory compression using streams
  (file/memory/blob/resource<-->file/memory/blob)
* Event hooks for customizable user interaction
* Built-in RLE (Run-Length Encoding) and LZH5
  (Lempel-Ziv-Huffman) compression
* Easy to add your own custom compression routines at any time
* Functions and examples to support compressed resources
  and self-extracting EXEs
* CompressString and ExpandString utility methods
* Key-based compressed data encryption
* Loads of example source included
* Full component source code available


Note: TCompress and its companions provide very comprehensive
data compression capabilities. Most developers might only need
to drop a TCompress component on their form and call its ExpandFile/CompressFile
methods in order to create and work with their own multi-file archives...

Others might drop TCDBMemo/TCDBImage/TCDBRichText components
on as well and simply interact with them to have text and picture data
automatically compressed when they are stored in a database.

...and some developers might use the TCBlobfield class to store all kinds
of data (sound, numbers, video etc) directly into compressed database blobs
-- see the BLOB.DPR (BLOB.MAK for C++) demonstration for an example of this.

Brief description:

TCompress provides native components for the creation of 
multi-file compressed archives, as well as database, file,
resource and in-memory compression using streams.
Three compression methods (RLE, LZH and LZH5) are built in, with
"hooks" for the easy addition of custom compression formats.

TCompress also includes drop 'n play components for automatic
database blob, image, rich text and memo compression, based on the
VCL's TDBMemo, TDBRichText and TDBImage components.

Images compress by up to 99% when using LZH, hence there is a
massive saving in disk space and disk or network access when
using these components.

TCompress comes with an extensive demonstration, many source
examples and comprehensive help and keyword files. Supports
Delphi 1.0, 2.0, 3.0 and C++ Builder.
