To unload libraries which you did not load is unsafe op- just as Stephen wrote. try delete twice the same object and you'll see what will happen. To perform this op, one has to know how they were loaded and unload them exact in opposite order. Moreover, he must know, that nobody else will try to unload these libraries too. I tried, and program failed. CFileDialog loads all these libraries for the very simple reason. It offers such service: one may open file from remote disk for example (or you may type an URL in address bar). Dear Stefan, you are not right about memory manager. I do not see physical addresses, but only virtual ones. In my virtual address space I have to have a continuous block of free memory in virtual address space to allocate large file (and no matter, what I use- VirtualAlloc, new or MapViewOfFile). I can clearly see fragmentation of my address space, when I run my prog under debugger. As I wrote, I had 1.2 GB continuous block before creation of CFileDialog and only 0.7 GB after it. If I can to download large file, I will do it. To split file is the last chance. Any idea, what headache will I have, if for example I need to rotate large file, which cannot be downloaded in memory?
