Compressed data in a .res file

[bobbie100]

The program I am working on incorporates a large amount of ascii data which is input as RC_Data within a .res file.
This data dominates the size of the executable.

Is there any way of storing the data in a compressed format (e.g. zip) within a res file, and then uncompressing when it is loaded at run-time via a resource stream?

I have used the ZLib data compression library which comes with Delphi 7 (and possibly earlier versions) to do something similar. It seems to work okay.

You would need to write a small Delphi program that compressed your data and wrote it as a resource file.

You then build your main program which would have another ZLib routine to decompress the data.

I would guess that the ZLib compression is reasonably good but I haven't compared it to something like WinZip.

I have used the Zipmaster 3rd party component, free to download. Always works ok for me.

Many thanks to you all for your suggestions. Plenty of options for me choose from.
