What practical ways can I reduce the filesize of Logos?

I'm not seeing any practical ways of deleting the resources I do not want downloaded on my computer? Why can't I view them by size? File management is almost non-existent. Unless I'm missing something?

I don't view any videos, it's just text. How do I isolate and remove them?

Here is a screenshot (from Space Monger) of just how much this program is taking up. A program consisting mostly of text. Surely I can decrease the size. Any help would be greatly appreciated. 30GB is a bit much.

Hi, Luke. Welcome to the Logos forums!

Your screenshot didn't show up. Use the paperclip icon.

But I can tell you how you can isolate the videos and remove them from your computer:

Open the Library (Ctrl+L, or Cmd+L on a Mac)

Type in this text in the "Find books" box: type:media video

(that will filter your library to show just the "Media Collections" and "Courseware Media Collections" which are actually videos; if you leave off the word "video" you'll also find audio resources and image libraries, etc.; you might want to remove those too, but you might not).

Now select all the resources that appear by clicking anywhere in the list of videos, on any field except the title or the cover image, and then pressing Ctrl+A (or Cmd+A if you're on a Mac).

Now hold down the Ctrl key (or Cmd if on a Mac) and right-click anywhere in the selected area. This menu will pop up:

You can choose either "Hide these books" or "Remove from this device" (odd inconsistent wording of those commands, but never mind that, even though these aren't technically "books" -- Logos recently renamed the more generic word "resources" to "books" in most of its UI; here was one mistake where they should have left it alone).

"Hide..." will hide from you the fact that you own the license for them and will remove them from both this device and any other devices you use Logos on, though you can always unhide them at some point in the future (if you can find them in the Hidden Books section of your Program Settings; easy enough if you've only hidden a few items, but gets tricky if like me you've hidden thousands of books).

"Remove from this device" will remove them just from this device but leave them on any other devices you use Logos on.

You might need to restart Logos for this to take effect.

Hope that helps!

Hey, thanks so much for the help.

That's given me 1GB more at least. The rest must be something else. All media I removed.

The Index (which is necessary for all your searches to work and gets rebuilt whenever you add more books to your library) takes up about 50% again as much space as all your books combined. So if you had 10GB of books, the index would bump that up to 15GB. Also remember that the books aren't "just" text. They contain all the formatting and tagging, and many of them have images embedded too. And there are all sorts of datasets that take up space. You can hide more books you're not using if you are still concerned about all the space your Library takes up. But hard disk space is pretty cheap these days. How big is your HD? A 500 GB drive is pretty standard these days, and even 1 TB isn't that expensive ($65 or $70), and even 2 TB is exceedingly reasonable at about $90. Logos's website says their minimum system requirements include 30GB of available disk space, and that is a minimum, so it will grow as you add books to your library. I doubt you'll be able to get it much smaller than that for very long. So if you are running tight on disk space, look for other software that you don't use to uninstall, or consider upgrading to a bigger hard disk, or adding a second drive if you've got a spare drive bay (if you're on a desktop computer). If you're on a laptop with a tiny hard drive (200 GB or less) you might be in a tough spot, because it's not easy to upgrade hard drives on those.

I don't view any videos, it's just text.

Your resources of type:media title:videos only contain links to download videos and are fairly small (up to 35 MB) when one video can be 98 MB. If you have deleted courses then it will be worthwhile to delete the download WebCache folder in \Logos\Data\random\. ("Quickstart...." media resources also download videos).

The largest resource I have is "Lexham Geographic Commentary on the Pentateuch" (595 MB), Carta Atlas and other Atlas/Map resources can be > 200 MB, but don't delete those that are useful. You can delete the old "Biblical Places Maps" resource (400 MB). Other books with graphic images can be > 90 MB.

Commentaries and Bibles are roughly 24 MB or less, so you need to be really selective in removing these. Monographs will be much smaller and you usually have many more of these than the other types mentioned.

After hiding/removing many resources you can reduce the size of the Index by using the command Rebuild Library Index.

If you are after big savings then look at the temporary files, recycle bin of your OS (4 GB or more depending) e.g. Disk Cleanup app in Windows.

BTW, you cannot reduce the amount of dataset files (not visible in Library). Depending on your base Library and/or Feature Set, this will be 4GB - 6GB.

I do a cleanout every few months of my webcache, which is now up to 4GB, and I delete the oldest files on the assumption that I've finished those courses.

BTW The New Encyclopedia of Archaeological Excavations in the Holy Land, Volumes 1–4 is by far my biggest resource at 824MB!
