APR_FOPEN_SPARSE may, depending on platform, convert a normal file to a sparse file. Some applications may be unable to decipher a sparse file, so it's critical that the sparse file flag should only be used for files accessed only by APR or other applications known to be able to decipher them. APR does not guarentee that it will compress the file into sparse segments if it was previously created and written without the sparse flag. On platforms which do not understand, or on file systems which cannot handle sparse files, the flag is ignored by apr_file_open().
