How does DCS cleanup/repair work?

I have some unknown modded files that are breaking integrity check. I want to clear them out. If I do the DCS Cleanup/Repair utility, it says it will get rid of files that are not official. Does this mean it'll get rid of custom or downloaded missions, or wipe bindings? What specifically will it target?

I did a repair yesterday, there were two options "clean ur mods" "not clean ur mods", forgot the actual options. I have gone with the option to clean my mods. After a while a box appears, which files are not vanilla, u can choose to backup them, they are saved in _backup000 folder in Dcs root folder

It appears to put removed files into folders in your DCS World installation named _backup.000, etc. (I see it's removed some files that I know I never modded. I guess maybe these are files that have been removed from the distributeable?)

And I don't understand why the Updater can't just do what the Repair app does.

^ It IS the DCS_updater.exe doing that work, repair and cleanup are just additional scripts / comands for it :).

Also, it already does what you suggest - when you update DCS, updater does the integrity check and replaces modded files in the root folder (thus its important to disable mods, or put them into Saved Games location altogether). Sometimes, player wants / needs to run these commands between updates for whatever reson, though, and that's why we can do it via links, command prompt window, or SkateZilla's utility.

repair will repair the build

To be more specific, repair replaces missing files. It not fix corrupted/edited files.

If you know a particular file is corrupt or modded in some way, you have to remove it first, then run a repair to get the "OEM" file.

I think, the updater checks at least the file sizes and replaces files where the size doesn't match with the original. I am not sure, if actually a checksum or something similar is calculated to find changed files - the repair mode of the updater seems to be a bit too fast to actually do that.

So, it is possible that local modification go unnoticed by the repair run if the modification does not result in a different file size, yes.

Nah, you're wrong, mate. It does replace modded files with downloaded originals, moving the modded ones to "backup" folder it creates. Always been like that as far as I know. Just tested it on current Open Beta to make sure.
