Greetings,<br><br>I am currently accessing datasets which are embedded inside a single file. Each dataset is a given file offset and length inside of the larger file. <br><br>I saw in the latest doxy-docs <a href="http://www.gdal.org/ogr/cpl__vsi_8h.html">here</a> that there is a VSIInstallSubFileHandler for doing just that, and look forward to testing it out. My concern with it, as well as the normal VSIMemFileHandler, is in accessing large files. I have 2 GB images, embedded within files that are up to 100 GB in size. Does the VSIMemFileHandler do any sort of paging so that the entire source image is not read into memory?<br><br>-- Dan Greve<br>-- Software Engineer<br>-- Northrop Grumman Corporation<br><br /><hr />Windows Live™: Keep your life in sync. <a href='http://windowslive.com/explore?ocid=TXT_TAGLM_WL_t1_allup_explore_022009' target='_new'>Check it out.</a></body>
