This file has been modified outside of Illustrator.

"This file has been modified outside of Illustrator. Do you want to continue?"

I keep getting this message. Anyone know what it means?

Still encountering the issue in OS High Sierra, despite Adobe releasing updates to CC 2018 last week...

I hate to throw a wrench in but this in NOT an Apple OS issue as I get the same error message with Windows 10 (Illustrator CC 2018). Happens a lot and even have had files that were saved and closed when re-opened be missing the latest edits.

This thread has been created in 2008. Here we are in 2021, 13 years later, and I am still seeing this error. I suspect this has to do with how Adobe software or creative cloud is saving and syncing your files. As soon as you make a save to your creative cloud folder, creative cloud (or photoshop, or illustrator) immediately tries to syncronize (or cache) the file whether or not the file is finished saving.* This can also be caused by software trying to constantantly trying to cache too frequently. Adobe has a bad history of not managing its cache very well. (There can be a life application here as well). 🙂 This leads to user's precious disk space needlessly being consumed. 

*To all software engineers: do you see this as a problem? Should we let the file finish saving, or coping, before syncronizing and caching?

I too am frustrated by seeing this message pop up repeatedly. The solution so far is to not save but save as. Give it the same name and it will ask you if you want to replace the file. Say yes and it is saved normally.

I am getting the same issue/message as well as having files I do in illustrator that I reopen telling me that the file has to be "recovered" which gets me a version of the file that is more like a pdf being opened in illustrator. You can work with it but the text is not connected and some of it is in outline - very frustrating. It happens with files that have been "modified outside of illustrator" more often. I have messaged Adobe but so far nothing. I beginning to wonder if Adobe is pushing its software

developers so hard to create newer and newer versions of its programs that it is neglecting to correct existing issues.

HI; I have the same setup as you have it seems. I have been seeing this "This file has been modified outside of Illustrator. Do you want to continue?" since I used to work off a server, which sadly has been forever. I know work off my One Drive which is on my local drive, but since it's constantly syncing, I wonder if that is why we're getting this message. 

Mac OSX Monterey

Illustrator 2022

Started getting this message with any file that is saved on Google Drive. Very frustrating. MacOS Big Sur, latest versions of Illustrator
