Windows Explorer or My Computer is slow
I would highly suggest you break up anything 1000 files and over (pictures, logs, videos,whatever) into subfolders in a tree fashion, since it would make accessing the directory/folder VERY SLOW.
This same "breaking files up into subfolders tree" idea applies to any kind of files, whether it be video files, from a security cam, or log files, or whatever.
In the past, some versions of kaspersky caused problems with anything that had more than 16384 files in a single directory. this has been fixed.
