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

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

[Randy CorpGraphics]

I too am having this same error with the latest incarnation of CS and OS High Sierra. Annoying to say the least.

[Magpie Marketing UK]

I keep getting this, since CC2018 and MacOSX update. It seems like a permissions issue, since mac went Intel this has been a repeated issue. Will check with our IT support and let you know once I fix this annoying bug!

[DavidMatos]

Still getting this on High Sierra after updating to CC 2018 today… Quite annoying.

[_bernard_]

I'm holding thumbs for Illustrator 2018.

[printlives]

I just started getting this a lot this morning after updating to the latest version.  I also recently updated to High Sierra, so may be related to that, although I haven't seen it till I updated Illustrator.

[MikeGondek]

Are you working off a server, if so what OS platform/server software?

Which did you do first update to High Sierra or Adobe CC 2018? Depending on your answer you may want to use the Adobe cleaner to uninstall and then reinstall.

[printlives]

No not a server. And I updated to High Sierra first, but am only on the latest update of Ilustrator 2017.  I'm not even seeing 2018 as an option.  But been thinking of running Cleaner anyway, cause I have pieces of a lot of old versions I'd like to get rid of.

[MikeGondek]

If you are not seeing 2018 as an option to update, then the adobe cloud app must believe you are on an older versions of mac os. You also may be running an old versions  of the Adobe cloud.

If you can start a new post that would be appreciated. Seeing a screenshot of your Adobe Cloud cloud would offer a lot of clues to help us troubleshoot better.

[SurajitS]

OS and Adobe CC all are upto date and working on a local system and still showing this message!

[mikeg_kale]

This is an old post since 2008. Please start a new  post and will be glad to assist.

Much has changed  from OS version to OS & Illustrator plug ins that are available, since then.  The previous replies only clutter up working and focusing on the variables that cause  your situation.

Cross your fingers.

I am getting this message too, but seems to be the autosave feature which has a bug... colleagues who have disabled auto save do not have the same issue.

I have switched it off and reverted to Astute Graphics' Autosaviour and issue has gone.

[ZyzinZ]

I have this all the time too. Many times Illustrator is the only app I'm using. I don't use auto save. I'm guessing it has something to do with the constant connecting back and forth to Adobe even though I don't (knowingly) use any Cloud features. It's more annoying than anything else. So far it hasn't caused any issues with my files. Using latest OSX and Adobe versions.

We have been trying to chase this issue of late without success: https://illustrator.uservoice.com/forums/601447-illustrator-bugs/suggestions/31674355-after-updating...

Please help us by emailing at sharewithai@adobe.com

few people reported it to Dropbox is that the only scenario?

Note: Illustrator does not support network or removable drives as scratch disks, or folders of file sync services such as Dropbox and Google Drive. We will still try to resolve this issue so please email us.

[sabt-PtO6Dm]

I use Google Drive all the time. This does make sense now.

[DavidMatos]

Same pain in the back here. Not related to sync services or removable devices. It's taking way too long to get this fixed. The way Adobe uses customers as beta testers with e-v-e-r-y  s-i-n-g-l-e update is just unbelievable.

[eYeLicker]

I’m seeing the same issue also recently upgraded High Sierra

[chrisuren]

Me, too. And I just upgraded to Illustrator CC 2018 (22.0.1), and am still getting the problem.

[MikeGondek]

This replies to this post have provided very little detail on this issue new issue  having to do with High Sierra. Help yourself and  Adobe to get you a better solution by answering these questions and anything else  helpful

Can someone  post more detail about:

1. exactly when (save as, save, export)?
2. does the error happen every single time?
3. type of drive: SSD, external drive, google drive, dropbox ? A screenshot of your drive would help as yo may have chosen the AFPS drive formatting?
4. has anyone  reformatting an APFS drive back to Mac OS Extended to try an resolve this?

1. exactly when (save as, save, export)?
   After Save.
2. does the error happen every single time?
   Every single Time
3. type of drive: SSD, external drive, google drive, dropbox ? A screenshot of your drive would help as yo may have chosen the AFPS drive formatting?
   Working Locoally on a Macbook Pro SSD with High Sierra installed. 10.13.1
4. has anyone  reformatting an APFS drive back to Mac OS Extended to try an resolve this?
   No.

Thoughts on why Illustrator is all of sudden, taking a locally worked on file and causing me to acknowledge that Yes I want to continue after making edits during a save onto the same exact file.

[mikeg_kale]

Hi BBi-TM,

Can you backup your data onto another drive, and try reformatting the APFS drive to Mac Extended as per the link I supplied?

[Sikarbi]

exactly when (save as, save, export)?

On saving existing .ai file

does the error happen every single time?

Not every. Sometimes program shows message (file error, cannot save - they may differ), sometimes it just crashes, leaving .tmp file in original file's directory. Sonetimes saves perfectly. One more thing: if i open .ai file's dir in Finder, click the file and after that deselect it, saving error sometimes disappears. Not sure about these cases, make not much tests on it.

type of drive: SSD, external drive, google drive, dropbox ? A screenshot of your drive would help as yo may have chosen the AFPS drive formatting?

Network drive.

Also, unable to save EPS files on network drive, error -47. It all started after updating to High Sierra.

Software version is CS6.

[MikeGondek]

With Apple offering software updates downloadable for free, unfortuanately our enthusiasm gets us to upgrade to soon.

Backup your data then

or wait for apple to put out an update.
