With the installation of the 64Bit version, the size of the application exe has increased significantly

Question / Problem

After installing the new 64Bit version of TreeSize Free, the size of the executable has increased significantly

Answer / Solution

Unfortunately, the previously used UPX compression no longer works under 64-bit. Therefore, the executable file in the 64-bit version is significantly larger than that of the 32-bit version.
One way to fix this is to enable NTFS formatting for the file or to use Windows' own compression (available from Windows 10).
