@ducklin
You mean in just windows without an open unity editor

So here is a simple trick

GOTO Your Project > Library Open any .Asset format file in notepad.
After opening the file you can see the unity version in the first line.

And what if the Library folder doesn't exist? A common use case is that one wants to know what version of Unity a newly cloned project was created in. All one will normally have in the project folder are the Assets and ProjectSettings folders, particularly if (as stated in the question) one hasn't opened the project in the editor yet! I$$anonymous$$O hexagonius's solution is the one that will always work.

This works, but I would add that it works with ANY .asset file under the asset folder too. I've just used this to identify an old 5.4.x project.

Under ProjectSettings in the project folder there's a ProjectVersion.txt.

It's ProjectVersion.txt, but apart from that this is the correct answer. The accepted answer involves the Library folder which may not even exist!

No it involves any .asset file in the assets folder. I've just used it to find out an old 5.4.x project number.

this should be the accepted answer.

if you're command-liney:

 cat ProjectSettings/ProjectVersion.txt | grep m_EditorVersion | cut -d ' ' -f 2

Here is what I found after going through all of my old projects:

For 5.x and later, the Unity version can be found in ProjectSettings\ProjectVersion.txt.

For 4.x, the version can be found by opening a .asset file in notepad and looking at the first few bytes.

I have yet to find a good way to determine the version for projects last opened in 3.x or earlier.

Looks like there is a file called version.txt in the Library/UnityAssemblies folder. The very first line is the Unity version.

Also, looks like you can open some of those .asset files found in the Library folder as text files and see the Unity version number a couple dozen bytes from the beginning, or so.

Nothing in the Library folder. So why do I get this error when starting up?

[Unity website won't upload my image atm] Text: Your project was last opened with a different setup of Unity. $$anonymous$$:/Alpha 16 The saved project (before 5.0) does not match the launched editor (5.3.3p3). This may require re-import...

Answer by RyanFavale · Aug 19, 2017 at 10:20 AM

Not seeing it in the first line of an asset. Only seeing something like this:

%YAML 1.1 %TAG !u! tag:unity3d.com,2011: --- !u!28 &2800000 Texture2D: m_ObjectHideFlags:..........................................
