amber shadow i want to move my app directory to a d drive and i do that and reopen the app i...

It's normal

#

First, close the app.

#

Then, you have to make a directory junction - from the location you moved it to, to the original location.

amber shadow Jan 17, 2026, 7:23 PM

#

what is that

carmine tapir Jan 17, 2026, 7:24 PM

#

To do that:

click Win+R, type cmd and press enter
type mklink /J %APPDATA%\ModrinthApp E:\Example\NewModrinth and press enter

#

But before doing it,

#

tell me which folders did you move specifically, that belonged to Modrinth?

carmine tapir Jan 17, 2026, 7:25 PM

#

amber shadow what is that

A directory junction is basically a shortcut to a directory on the drive

amber shadow Jan 17, 2026, 7:25 PM

#

i whanted to move it to D:\Modrinth App or just on my d drive if that is what you mean

carmine tapir Jan 17, 2026, 7:25 PM

#

What did you want to move specifically

#

The whole %APPDATA%\ModrinthApp or e.g. a profile folder?

amber shadow Jan 17, 2026, 7:25 PM

#

yeah

carmine tapir Jan 17, 2026, 7:26 PM

#

Which one

amber shadow Jan 17, 2026, 7:26 PM

#

appdata

carmine tapir Jan 17, 2026, 7:26 PM

#

Alright

#

Then do this:

click Win+R, type cmd and press enter
type mklink /J %APPDATA%\ModrinthApp D:\"Modrinth App" and press enter

#

If any error appears send a screenshot here

#

Remember to close the launcher before this

amber shadow Jan 17, 2026, 7:27 PM

#

mklink /J %APPDATA%\ModrinthApp D:"Modrinth App" paste that in the cmd?

carmine tapir Jan 17, 2026, 7:28 PM

#

yeah but remember to put the \ after the D: if it's not there

amber shadow Jan 17, 2026, 7:28 PM

#

this?

carmine tapir Jan 17, 2026, 7:29 PM

#

nah just remove that character (i meant to put it after D: but its there so)

amber shadow Jan 17, 2026, 7:31 PM

#

it says it doesent exist

#

carmine tapir Jan 17, 2026, 7:31 PM

#

amber shadow Jan 17, 2026, 7:32 PM

#

carmine tapir Jan 17, 2026, 7:32 PM

#

okay are you sure that the full path that you moved it to is D:\Modrinth App?

amber shadow Jan 17, 2026, 7:34 PM

#

carmine tapir Jan 17, 2026, 7:34 PM

#

#

amber shadow Jan 17, 2026, 7:36 PM

#

carmine tapir Jan 17, 2026, 7:36 PM

#

#

amber shadow Jan 17, 2026, 7:37 PM

#

carmine tapir Jan 17, 2026, 7:37 PM

#

#

#

try doing mklink C:\Users\Gebruiker\AppData\Roaming\ModrinthApp D:\"Modrinth App"

#

(without the /J)

carmine tapir Jan 17, 2026, 7:39 PM

#

amber shadow this is stadard

btw can you change it in the app itself?

#

or does it not have an edit option, only seeing

amber shadow Jan 17, 2026, 7:39 PM

#

its says denied

amber shadow Jan 17, 2026, 7:40 PM

#

carmine tapir try doing `mklink C:\Users\Gebruiker\AppData\Roaming\ModrinthApp D:\"Modrinth Ap...

on this one

carmine tapir Jan 17, 2026, 7:40 PM

#

Alright

amber shadow Jan 17, 2026, 7:40 PM

#

if i try to change the thing in the app it gives me this error code

carmine tapir Jan 17, 2026, 7:41 PM

#

amber shadow on this one

That means either:

You have Modrinth running (do taskkill /f /im Modrinth App.exe and try again)
The appdata\ModrinthApp folder got recreated - delete it
You need to do it via cmd

carmine tapir Jan 17, 2026, 7:41 PM

#

amber shadow if i try to change the thing in the app it gives me this error code

Wait

#

Now I think the issue could be your D:\Modrinth App folder

#

Did you do something with its permissions?

amber shadow Jan 17, 2026, 7:42 PM

#

do i have to turn on full premission

#

top 1

carmine tapir Jan 17, 2026, 7:42 PM

#

Did you do anything with its permissions yes or no

amber shadow Jan 17, 2026, 7:42 PM

#

i dont think so

carmine tapir Jan 17, 2026, 7:42 PM

#

Hmm

#

Well then it shouldn't be the cause

carmine tapir Jan 17, 2026, 7:42 PM

#

amber shadow top 1

Is the PC you're using shared with other people or do only you use it?

amber shadow Jan 17, 2026, 7:43 PM

#

only me

carmine tapir Jan 17, 2026, 7:43 PM

#

Alright. Try setting permissions to all checked for every user for the D:\Modrinth App folder

#

and trying to run Modrinth App again

#

If it doesn't work and you have no idea why, try running Modrinth App with administrator

amber shadow Jan 17, 2026, 7:44 PM

#

do you whant me to turn my pc to inglish so you can read it

carmine tapir Jan 17, 2026, 7:44 PM

#

Nah i use google translate (Incase I need it)

carmine tapir Jan 17, 2026, 7:45 PM

#

carmine tapir If it doesn't work and you have no idea why, try running Modrinth App with admin...

(like this:

amber shadow Jan 17, 2026, 7:45 PM

#

did that

carmine tapir Jan 17, 2026, 7:45 PM

#

Does it work now?

amber shadow Jan 17, 2026, 7:46 PM

#

do i change in the app or mklink C:\Users\Gebruiker\AppData\Roaming\ModrinthApp D:"Modrinth App" this

carmine tapir Jan 17, 2026, 7:48 PM

#

If it works after running it as admin or after mklinking it then it's good

#

If it works only after running as admin, well, I guess that's the only way

amber shadow Jan 17, 2026, 7:49 PM

#

denied again

#

i can try to change it in the app

fiery kiln Jan 17, 2026, 8:13 PM

#

carmine tapir (like this:

!!notadmin

#

!!noadmin

edgy cargoBOT Jan 17, 2026, 8:13 PM

#

fiery kiln !!noadmin

✋ Do not run launchers as Administrator / via sudo

Please do not run any Minecraft launchers as Administrator (on Windows) or using sudo (on Linux).

This poses a high security risk, as it grants the launcher, Minecraft, and every mod it loads full access to your system.

Moreover, it never actually solves the issue you might have with your launcher.

carmine tapir Jan 17, 2026, 8:14 PM

#

i know but when theres no other way then its worth a try

tough horizon Jan 17, 2026, 8:14 PM

#

imaginary i pinged you can you help

fiery kiln Jan 17, 2026, 8:14 PM

#

did he try to reinstall app?

carmine tapir Jan 17, 2026, 8:14 PM

#

reinstalling will recreate the %APPDATA%\ModrinthApp folder

fiery kiln Jan 17, 2026, 8:15 PM

#

so?

#

did he try?

carmine tapir Jan 17, 2026, 8:15 PM

#

it's probably better to just move it back

#

well i didn't suggest it as it's pointless imo

tough horizon Jan 17, 2026, 8:15 PM

#

carmine tapir i know but when theres no other way then its worth a try

did you blocked me 🙁

amber shadow Jan 17, 2026, 8:15 PM

#

i was afk

#

mklink /D "C:\Users\Gebruiker\AppData\Roaming\ModrinthApp" "D:\Modrinth App" @carmine tapir idk how this works

carmine tapir Jan 17, 2026, 8:19 PM

#

amber shadow mklink /D "C:\Users\Gebruiker\AppData\Roaming\ModrinthApp" "D:\Modrinth App" <@1...

If it shows an error then I really have no clue how to do it otherwise

#

If C:\Users\Gebruiker\AppData\Roaming\ModrinthApp exists you can rename it and then try again

#

**fixed typo

amber shadow Jan 17, 2026, 8:20 PM

#

it says cant make files that already exists

carmine tapir Jan 17, 2026, 8:20 PM

#

carmine tapir If `C:\Users\Gebruiker\AppData\Roaming\ModrinthApp` exists you can rename it and...

^

amber shadow Jan 17, 2026, 8:21 PM

#

rename that name?

carmine tapir Jan 17, 2026, 8:22 PM

#

rename the ModrinthApp in appdata if it exists in there

#

and then mklinking again

#

you can try with /D if you want

amber shadow Jan 17, 2026, 8:23 PM

#

cant i rename C:\Users\Gebruiker\AppData\Roaming\ModrinthApp to D:\Modrinth App

carmine tapir Jan 17, 2026, 8:23 PM

#

that doesnt make sense

#

you would rather want to do the opposite

#

but you probably want to make it stay on the other drive so thats why i recommend using mklink

amber shadow Jan 17, 2026, 8:24 PM

#

i whant it to be on the d drive

carmine tapir Jan 17, 2026, 8:24 PM

#

exactly

amber shadow Jan 17, 2026, 8:27 PM

#

i dont get it

wise jacinth Jan 17, 2026, 11:18 PM

#

amber shadow cant i rename C:\Users\Gebruiker\AppData\Roaming\ModrinthApp to D:\Modrinth App

Gebruiker? Hi fellow dutchy

#

Just deinstall it and copy the instances you wanna keep, then reinstall it on D and copy over the instances folder you saved

#

Don't see an easier fix, sry

#

@amber shadow

amber shadow Jan 19, 2026, 3:59 PM

#

@wise jacinth how do i do that
