(My 2TB disk is not sufficient anymore it seems )

I recently went from a dedicated 2TB drive to a 4TB one for DCS

Ah ok

I'll try that

(I haven't made the plunge into DCS ww2 yet, so that's quite a heavy chunk of data not being used)

Mind you, aircraft external models and textures will always be downloaded whether you own these modules or not, because they have to be usable on your computer  as AI units, or other players' units in MP.

But it's the terrain modules that have always had the biggest disc footprint in DCS.

Well, it kinda was a surprise to me..

Is this because of the Corsair and Marianas ww2? (both of which I don't use).

I wish ED came up with some way that would allow us not having to download stuff we don't use.

 

(My 2TB disk is not sufficient anymore it seems )

I've been writing for a while that a DCS launcher should have a simple thing – a file manager. Something like ORBX invented a long time ago, but not only that, like Steam, GOG etc. You simply specify the path where you want your installation. For example, DCS is on drive C, terrain on drive D, and modules on drive E. I personally have a dedicated drive for DCS that's 4Tb, but many of my friends have stopped buying new maps because they don't have the space on their drives and don't want to delete old maps to install new ones. Furthermore, each patch actually means more space. DCS is hungry and uses up space quickly. I think 2TB is currently too little and will probably last for about a year and a half, but it's also not good to have a drive that's completely full, especially with an NvMe system, with a maximum of 80%.

I missed the previous update, so I now have to do the last 2 updates at once. When doing so, I get a warning that I don't have enough disk space and that the update is a whopping 149GB! 

Ehr.. that can't be right now, can it?

In this case, there was a substantial Germany update and IIRC recently also big Kola and Sinai updates (not sure if they'd have been since you last updated) but very plausible with maps that it could be 149 GB.  Fortunately most of that will replace existing, so you shouldn't need fully that much more space on your drive.

No. Corsair core module is 5GB and Marianas WW2 is 9GB, but the latter is optional - you can select it in Module Manager. DCS grows with additions of new units and what you buy and download of course. Patches mostly replace the files with new ones but the unpacking process also needs space esp. for maps.

Anyone having issues launching into VR?  DCS loads fine - if a little slower than usual - into desktop mode, but when I select VR from the launcher menu it just stays on the loading splash screen.  I waited 5 mins+ twice and it didn't start.

After some digging I found a _backup.001 folder in my DCS install, which contained 227GB of terrains, which are normally installed via aliases on another drive.  Anyway, after deleting this it loaded up as normal, both in VR and Pancake.

Depends on maps and modules owned and installed!

There was an update to the Sinai map that was huge, and if you have a lot of Modules that get fixes, the overall install size of DCS can get quite large.

During downloads, decompressing the downloaded stuff and installing/replacing the files, it requires some additional, temporary space.

If you have everything on the same disk/SSD, you should clean up things like track files (especially the large multiplayer ones), if you use TacView delete old TacView files and if that doesn't free up enough disk space, consider, temporarily deinstalling  currently not used campaigns, modules or maps, until you can add a larger or better dedicated game / DCS disk or SSD.

You can use windows file system junctions for that (distribution of folders to different drives), but I recommend a dedicated 2TB SSD for DCS, I have mostly everything, installed and a bit less than 1.2 TB used.

This is just a workaround. I have some of friends who don't even install mods because they … understand how :). While it's not quantum physics, it's hard to expect everyone to know how to do it. If ORBX has this option for its add-ons, why doesn't ED do it?

[Esac_mirmidon]

The virtual link option between Hard Drives works fantastic of you dont have enough space. Sharing files like that doesnt make any impact on perfomance. Worth a try.

Yup, and it's also a trick to save space if you want to run multiple server instances. Just remember to shut them down pre update.

Hi all,

 

Unfortunately, this last DCS Update broke the LUA Console of my DCS-BIOS setup. It established communication with DCS, but the console commands are ignored.

I'm not knowledgeable enough to fix this myself, so for now I will install as a workaround, a small prior-version DCS Core with just the Marianas map (to save space) and the aircraft I'm currently flying (T-45C User Mod, F4U and M-2000C), and run it only when I need to learn the parameters and indicators of a DCS aircraft.

Could it be a potential side effect of the new "sanitization" of the dostring command?  Did you try putting in the autoexec.cfg in this thread?

Thanks for the tip, didn't knew about this change .... will investigate, thanks a lot.

That was it! ... thanks a lot for the help, the DCS-BIOS uses the following script in /Hooks/

 

DCS-BIOS-LuaConsole-hook.lua

After reading the post, I added these lines to my autoexec.cfg

 

if not net then net = {} end
net.allow_unsafe_api = {  -- this defines the secure zones where net.dostring_in() should be called from
  "userhooks"
}
net.allow_dostring_in = { -- and this defines the scopes that you want to use from net.dostring_in()
  "mission"
} 

 

... and the issue got solved  

thanks a lot, I learned something new  

 

Best regards

I have benefited greatly from your training missions on various aircraft, so it makes me VERY happy to have been able to give back to you!!

Any idea when Currenthill's products will be available in Core DCS?
Still in 2025 or later ?

This is an advanced feature of your windows OS and filesystem implementation, designed specifically to allow for flexible redirection, virtual folder integration (e.g. adding the same Missions or config folder to multiple DCS instances) and is used in professional IT systems, a lot.

I don't mean to be rude, but it is definitely worth to learn these advanced options of your Windows OS, not only for DCS...

Well, as you write, these are advanced options, in other words - for people very savvy in IT and Windows aspects. Remember, however, that many people have very basic knowledge of how the system works and expect software to be a complete package with the most important functions, leaving nothing else to be touched. Adding a File Manager to the DCS Launcher isn't quantum physics or a rocket science. ED should have done this, and in my opinion, it's losing out significantly, as some people have stopped buying new maps due to disk space issues, or rather, the lack of it. 

Personally, I don't have a problem with this because I replaced the DCS drive with a 4TB NvMe last year so it will last for a while and I only have DCS here However, not everyone has such opportunities and these people should be remembered.
