Good Day,

So, today my library consists of ~9400 resources. Disk space is usually not an issue for me. However, recently, I've noticed that Logos has opted to consume about 80+ GB of my 230GB SSD. While this usually isn't a problem, as I have a 1TB HDD for some apps and most data, I don't want to put Logos there if possible. I enjoy the quicker access that the SSD provides. So, while I normally have ~20GB free on the SSD, sometimes it gets down below 10GB. As soon as I get a new resource and indexing starts, I often run out of space, and need to temporarily move some other data to my HDD. This is of course, cumbersome. 

Anyway, I went spelunkering in AppData\Logs\Data where the vast majority of this 80+GB is. BTW, I've already disposed of the majority of my video content by going to each course and purging the downloaded content. What remains appears to be split between the Library Index - 20GB, Resource Manager - 40GB, and the WebCache - 22GB. I suspect the first two shouldn't be messed with. However, I'm wondering what liberty I have, if any in purging the WebCache when it gets as large as it is now. Can I just delete files? If so, is there any preference I should give to some files over others - e.g. older files? If it is ok, how will this affect performance?

BTW, I know some of my content usage is due to quite a few books that I have from books.logos.com which being facsimiles probably take up more room than regular books. Some of them are on pre-pub, and as soon as they go live, the facsimile will go. However, if possible, I'd rather not nuke those books now.

So, what about the web cache? Is it an option for freeing up space?

Thanks,

Dave

HI Dave, I am not an expert lol, but in my experience I believe every file in WebCache is video (may be a bookkeeping file or two related to the videos)  - so it can be deleted. You can verify this by COPYING a file say to your desktop, rename the extension as MP4, and then play it. You can check all the files if you like. In my uninformed opinion I would say delete away - or at least move them somewhere for a day or two and verify that Logos still works fine!

Found some threads about WebCache => Logos Web Cache is rather large and => Download all media and space question... that have replies from Faithlife employees, including => https://community.logos.com/forums/p/106720/738345.aspx#738345

Angela Murashov:
The WebCache stores all the downloaded media files so then you can watch videos, play audio or see the images while the app is running offline. If you decide to delete the files then make sure to do it while the app is not running.

Hi Dave,

The WebCache is the only folder that can be safely deleted. That contains any images, audio and video that you have downloaded or streamed within Logos.

However, you do have another option, both with WebCache, and with other folders, and that is symbolic links.

Symbolic links aren't officially supported, but they work just fine. Here's what you need to do:

  1. Install the free Link Shell Extension.
  2. Make sure Logos is closed.
  3. Move your WebCache folder onto your secondary drive.
  4. Right-click on the WebCache folder you've just moved and click "Pick Link Source".
  5. Go to the folder where WebCache used to reside. Right-click in some empty space and choose "Drop as... Symbolic Link". The folder will re-appear (probably with a little shortcut icon), but if you double-click on it will act as though it's still on Drive C:.

You'll now have your WebCache folder safely on a different drive, and Logos won't know any difference.

(Theoretically you can move any Logos folder in this way, but if you're moving from an SSD to a HD, you'll notice Logos performing more slowly if you do.)

Thanks so much. This is really good feedback, and offers me a couple of options.

Very interesting! Thanks for this tip. I must try it.

Are there any other folders that might be good candidates for moving off your SSD, in this manner, without taking too much of a hit in performance?

Could try relocating Data \ <random> \ ResourceManager \ Resources folder from SSD to hard drive.

That will affect performance significantly.

Depends on application usage whether noticeable or not; hence "try" relocating.

FYI: on a 27" iMac, available space on internal SSD provided incentive to relocate 62 GB Resources folder to an external hard drive.  Thankful for decent performance; seems initial opening of resource can be a tad sluggish.

Almost every operation in Logos will use the Resources folder. If you have lots of RAM, you'll only notice a slow down when resources are first loaded. If you have less RAM you'll notice a more consistent slow down. Moving it is certainly an option if you want to save space, but there will be a performance hit, as you say.

Or you could install a bigger SSD

There are other places to look but I found these SSDs listed on Newegg

SAMSUNG 860 EVO Series 2.5" 1TB SATA III V-NAND 3-bit MLC Internal Solid State Drive (SSD) MZ-76E1T0B/AM $199.99

Crucial MX500 2.5" 1TB SATA III 3D NAND Internal Solid State Drive (SSD) CT1000MX500SSD1 $191.99

WD Blue 3D NAND 2TB PC SSD - SATA III 6 Gb/s 2.5"/7mm Solid State Drive - WDS200T2B0A  $339.99

This is what I did last week for exactly the same reason, every time Logos indexed I was getting constant notices that I was out of hard drive space and it would start shutting down other programs. Then, if it managed to eventually finish indexing, my storage space would jump back up. I got tired of moving and deleting files, so I replaced my SSD with a larger one and now I'm fine.
