*return 0																*
*WriteC() :write a character c to file fp if succeed	return 1 ; if has*
*error then show errormsg and return 0									*
*ReadC()  read a character from fp and if succeed	return the character;*
* if has error then show errormsg and return -1							*
*WriteStrToF(str, fp) write the string str to fp end with \0			*
*WriteLIntToF(a,fp) write the long int a to file fp as the haig bits	*
*first order for example 1 writed as 0000 0000 0000 0001;				*
*Compress(InFileNames,OutFileName) compress files InFileNames to		*
*OutFileName and return The Size of it if filed return 0				*
*CreateFolders(filename) create the folder structure of the filename	*
*need for example filename = c:\a\b\c.exe but there is not c:\a\b then	*
*it will create the path c:\a\b											*
