Dll and ocx files download starting with Q: Q.dll Q2BTNS.DLL QA3D.DLL

DLL or Dynamic-link library files are vital parts of any operating system. For example, files Q2BTNS.DLL and QA3D.DLL are frequently used by Windows. They are applied in various situations and are launched to support not just one, but several programs. DLL libraries QA3DLOAD.DLL and qad2wpg.dll are also frequently used by various programs from service commands to drivers as they are external compiled subprograms that are used to enable ActiveX control elements work. Dynamic libraries qagame_mp_x86.dll or QALOWMEM.DLL work opposite to static libraries (you can recognize them by .lib file extension) and are not connected to executable files by links editor. qasf.dll and qasf.dll are typical DLL libraries that start working only when the program they work with is executed.

First versions of Windows OS as well as applications for it had very limited functionality because of lack of memory. At that time is was nearly impossible to perform several operations at the same time, so it was clear developers needed a solution that would solve this problem. The answer was easy – modularity system allowed connecting various libraries at different stages of work, so they were simply changing one another, f. ex. like QBA.DLL or QBCONV.DLL. Technical progress increases memory capacity, but it also makes computers and operations they perform more sophisticated, so today DLL libraries contain from several thousands to tenths of thousands of files. In the result separated libraries start emerging process and different versions of same DLL file appear (you may want to download QBFORMS.DLL or QBINTRV.DLL). Such emerging often causes same problem - popular DLLs (like QBool.dll or QBPAY.DLL) can be deleted during software deinstallation, but there are still programs that need it.
