The standalone binary is no longed compressed, as it is distributed in an compressed archive anyway now. The installed binary was never compressed, it had always this (larger) size.

Just curious why the file size of the executable release of WinSCP (Winscp.exe) is substantially larger? Version 4.2.5 was 1.56 MB in size. The release I downloaded today 4.2.8 is 6.06 MB. Why this big difference or did I do something wrong in the download.
