Reducing application EXE size

3 comments. Current rating: (1 votes). Leave comments and/ or rate it.

In a small project I tried to reduce the application's EXE size. It seemed that I needed to include unit Forms because I needed the application's startup directory.

I then remembered that ParamStr(0) contains the same information as Application.ExeName and my EXE file shrank from 290kB to 43kB.

After using UPX it now has a size of only 22kB!

	// this version needs unit Forms uses Forms; begin sPath := ExtractFilePath(Application.ExeName); end; // this version does not! begin sPath := ExtractFilePath(ParamStr(0)); end;

I don't understand the variable sPath it's supposed to contain the path of the exe file, but how do I use the sPath := ExtractFilePath(ParamStr(0)); Please help, cause this is what I need to reduce the size of my application. Thanks Francisco

ParamStr(0) is full path + name of your executable. What he does there is extracting the path without the exename. if your app is c:\bla bla bla\test.exe then using the 2nd sample you would end up with c:\bla bla bla\

This does nt work for Webmodules/IIS dll. Use ExtractFilePath(GetModuleName(HINSTANCE));
