Illustrator Resizes on File Open

Hi everyone
I'm not native English speaker, so sorry in advance for my English if it's not so correct.
I'm still using CS6 version of Adobe Illustrator (in 2023 )) for Windows. So I can't say how it works with newer versions.
I have faced with this issue long ago as well. It really annoys )

But it only occurs when you use regular Windows explorer (when you double-click on AI file in Windows explorer).

So if it's still relevant and maybe will be helpful for somebody, you may simply use... Adobe Bridge.

I have noticed such thing...
If one double-clicks AI file in Bridge it opens in Illustrator not resizing the Illustrator window itself. It remains maximized if it was maximized and it remains the same size if it was resized.

Maybe it needs more time to run and is not so fast as windows explorer, but you run it once and if you work with lot of files, I guess it worth to use it to avoid that issue.
Besides that Bridge has its own benefits while using it, sush as fast file filter, file rating and labeling, editing metadata, making collections, exporting multiple files, viewing and selecting files in the form of a carousel and many other features...

P.S. If such a solution has already been proposed, or it is known to everyone, then just ignore this post)

I am on v27.1.1 (2023), and there is no solution for this problem, yet!

I have a different but similar problem. My window doesn't minimize, but it opens to the left and i have to click the green + button in upper right corner. I have not tried to delete the prefs file, not excited to do that. But I may see if it helps. Sometimes my windows open almost off the page. If it's one, no problem, i drag it back, but often it will be all of them. I have to reset my workspace. This is something new, never saw this on previous versions. I am on version 27.01 2023.

Hi, everyone! : )
I see this was posted on 2012.
It's august 2022, I'm using the latest Illustrator version on the latest Windows 11 version and this is still an issue. Any solution yet? I'll be grateful for any solution! 😅

Greetings from the year two thousand and twenty two. Illustrator still arbitrarily resizes itself when opening files, seemingly with no connection, rhyme or reason between them. You never know when it will happen, you can't even predict if it will happen with the same same file on the next open! 

What was it like working professionally in Illustrator in 2012 btw? I barely used it myself back then. I know it can be difficult to respond from the past, but I'm curious what it was like when creative cloud wasn't stuffed in your face everywhere... or did y'all already have that plague a decade ago too? Feels like there was a good chunk of my childhood when adobe was pretty clean of that kind of disease, but maybe I imagined it. Anyway, cheers friend, we are connected through time you and I, through this ancient unsolved illustrator issue. 

I'd just like to add that this is still an issue

Hi All, there's a temp fix to this issue in Windows.

Close Illustrator

Locate your Start Menu Illustrator shortcut file - for me it's in C:\ProgramData\Microsoft\Windows\Start Menu\Programs (or click Start, right click Illustrator > More > Open File Location)

Open the shortcut's Properties

Change the "Run" dropdown to "Maximised"

This solves the bug for me until the next time I update Illustrator.

If the above doesn't work, you could try doing the same change to the shortcut within your Adobe folder - for me it's in C:\Program Files\Adobe\Adobe Illustrator 2021

Shame on Adobe for not fixing a 10 year old bug.

Like others, I also sometimes need to open an .ai file from Windows File Explorer, and just found that the best workaround (for me anyway) to avoid the AI window minimizing or 'restoring' is, instead of double clicking on the file, just go right click>Open. I tried it just now on a few of the files that had collapsed the window before, and by right clicking then clicking Open on them instead, they opened fine without collapsing AI. For some unknown reason, for me, the collapsing effect happens with some .ai files but not others, even though they're all similar. In my case, 18 x 24 inch posters. Anyway, it's not a fix for the root problem but maybe this helps some people.

Almost 10 years later and this is STILL HAPPENING?!! Not only does the Illustrator window resize itself, it also collapses half of my panels. Super annoying!! It is a 'silly little issue', but frustrating nonetheless. I would prefer to double click my file to open it, but instead I have to use the File > Open in the menu so this doesn't happen. Photoshop never does that. Why does Illustrator?!!

I'm really surprised to see that this problem has existed for so long. I work on templates and constantly only use my keyboard for manuvering around Windows File Explorer. This problem has caused me a lot of down time as I usually open up 3-6 documents at a time and I never know which ones won't open because Illustrator wants to do it's own thing. I can't exactly ignore my mouse when I have resize Illustrator.

Adobe really needs to get on this. An entire DECADE with the same problem? Come on. That's just bad.
