I want to use libraries and the homegroup to share my files in an easy manner. However, i only want some files from folders (including the harddrive i've got, that has 100+ ER episodes in root and a bunch of other folders - i only want those ER series and nothing else) showing up in libraries, not the whole folders. There is a workaround for this when using libraries with windows explorer - you can use a saved search. However, if you want to access libraries remotely via different software (MediaBrowser, for instance), there is no way to use saved searches. Suggestions?
No, you can only add folders/directories to libraries.
Move the files into their own folder and add that to the library.
Moving a file within the same hard drive will take no time at all as you are simply updating the pointers that tell the OS where the file is. You aren't actually moving the file.
