For those who downloaded the Perseus library, you more then likely are faced with the problem of having hundreds of resources in language that you cannot read. I looked for some guides on how to mass hide resources, but everyone seemed to suggest dragging the resource one by one into the hidden resource window of the program settings.
Here is a much faster way of mass hiding resources. Note that I am an example of how to mass hide by language (Latin), but I am sure you can easily apply the method for other needs.
1) Right Click on the Library tab and click "Open in a Floating Window"
2) Right click on the sorting columns (i.e. Title, Author, etc.) and choose a convenient filter. For instance, in my case I chose Language.
3) Sort your library using the columns
4) Select multiple resources using the Ctrl + Left Click or Shift + Left Click (For instance, I sorted by Language > Latin and Shift + Click to select all of the texts)
5) On windows, Ctrl + Rick click brings up the option "Hide Resources," which will remove them from your library and hard drive, although they can be restored later.
I hope this helps somebody.
