Dynamic Link Library Files

Dynamic Link Library files (.dll files) are used so different programs in Windows can share the same functionality. Normally these would be systems files on one's de-NIST list - non-responsive electronic files to be removed for the data set for review. However it is possible to view the contents of .dll files and see which functions they specify.

NirSoft's DDL Export Viewer can be downloaded here. It will generate a list of functions in each .dll file. Just a little Window into the obscure world of system files.

Folder Axe

Everyone should download and install the free utility Folder Axe. It lets you easily segment (by moving or copying -see the option in the red box in the screen grab below) files from single source folder by size, file type, date, file name or a fixed number, and put them in multiple new folders.

Even better you can automatically save files in encrypted zip files when preparing something for production.

Paging file size

Windows contains a feature designed to deal with performance issues when you're running out of RAM. The pagefile.sys stores memory for applications you have open, but have not used recently, so that more memory is available for the applications you are using. When you back to the applications after a long time, it should take longer for them to function again.

If this is really causing a problem for you while you're processing a lot of data, there is a way to adjust the pagefile.sys setting. Right click on Computer in Windows Explorer and choose Properties . . . then Advanced System Settings.

. . . next click on the Advanced tab, and then Settings in the Performance section. A Performance Options dialog box will open. Go the Advanced tab again and click on Change in the Virtual Memory section.

You'll know see how you can either deactivate the paging file size, or specify its parameters.

The drawback to doing this is that if you then do exhaust the system's RAM with the open applications, they will crash very quickly, since Windows cannot re-assign virtual RAM.
