Yes for singleplayer. You have to edit the level.dat file.

So sorry if this is answered somewhere, but 52 pages is a bit to read through and I'm a first time, only timer with a question;

Long story short, lost my saves when my SSD OS failed and forgot to try and pull them off before a wipe. I've tried a few different recoveries but SSD files seem gone but an older version on my HDD was found BUT--

There is other bits of data scattered in, at least, the level.dat file (I used notepad to view them (sorta), and that one seemed to be the only one with injected lines of actual words from overwrites).

Question: Can I use NBTexplorer to open/repair these files at all? Use it to do *anything* with the files to see if I have a chance at recovering the save(s)? Years of creative work at stake.

EDIT: Nevermind. I finally got in to try and its gone. There's too much data sparsed through everything and it won't recognize some, and can't read others.

guys i couldnt open my data file which contain villages.dat when i click the expand button and the expand button just dissapears and nothing happens ... Pls help

Minecraft version - ?
NBTExplorer version - ?
Host OS - ?

This may be answered somewhere in the 52 pages, so apologize if a stupid question. I have an .nbt structure file and I want to replace all examples of one block (andesite) with a different block (polished andesite). I feel like this ought to be possible but can't quite tell how to go about it. I got the .nbt file open and found where andesite is in the palette section... do I just change it there? or somewhere else? Thanks for the help!

It strongly depends on WHERE you want to change it.

You can try changing the world time. But make backups first.

Hi. Thanks for supporting the tool! ^^
Is it possible to clear all untouched chunks with this program? I have map bloating issue... and if i can, will it cause bugs, like visible slices between old-generated and after-cleaning generated chunks?

No, the program don't have this kind of automation built in. You COULD probably do it by hands, but that would be labor intensive and error prone.
There should be no gaps in generation, if you did not change the generator or world(level) seed. At most, minor changes in decorations' locations.

Hi, is it possible to take the multiplayer player.dat file for a player and change it so that it looks at a completely new account instead, giving the new account everything the previous account had?

This is so that a player can purchase a new account instead of using the current one.

If so, can you suggest how please?

Thank you.

You can just rename the file. There's nothing in it that is specific to account.

My files are in .pak instead of .dat?

You don't "edit biomes", you "edit NBT files and derived formats".
You have to know the content and meaning of the edited file to change it.
Look for chunk format description on MCW.

Hi there, I have a custom island world I downloaded and am attempting to set the world generation of the world outside the island's area to ocean so I don't have unsightly sheer cliffs.

I couldn't find any explanation on how to edit world generation with this tool, just posts saying it is possible. Any information on what to edit and what to write would be immensely appreciated.

Check the "Superflat" wiki article.
You'll need something like generatorName: FLAT, generatorOptions: 3;bedrock,63*water;deep_ocean;"

On the windows installer on windows 10, I'm getting an error code (2755) with no other info apart from saying "The system cannot find device or file specified"

I tried installing it on C:/NBTExplorer (vs the default location) and it made no difference.

I also tried creating the folder (C:\NBTExplorer\) And reinstalling at that location, it made no difference.

Scratch that, Turns out if you have file encryption enabled in the point of execution (of the installer) it will brick, perhaps it creates a file at the installer location and fails to read it as it's in an encrypted space.

Whatever it was, it can be fixed by running it in a location such as C:/ (or anywhere without file encryption probably)

My path follows; C:\Program Files (x86)\NBTExplorer. This works on my windows 10.

I cannot recall whether I made the directory or the computer created it.

HTH
