SparseFile is about saving disk space on the server; not about saving bandwidth....) A quick test on Windows2000/NTFS: Cygwin works as expected, including the savings. On plain Windows, the full size of the file is allocated, although the checksums of the files are correct. For now, it looks safe to use SparseFile in your platform-agnostic application. What about OS/X? BSD? gegroet, Erik V. - http://www.erikveen.dds.nl/
