Why have I lost all my work?

I'm relatively new to Illustrator. Last night, I lost about 8 hours worth of work I put in a project of Illustrator, and I have no idea why. I was wondering if anyone could shed some light on the situation.


At one point yesterday morning, I recorded my project in PDF format so that I could share it with someone. I continued to work on the file and kept saving my Illustrator project that I worked. At the end of the day, I closed my project. When I tried to reopen this morning, all my changes disappeared. Even more strange, the only version of the Illustrator file I have is a version even older than what I had saved in PDF format. And still more strangely, I got a PDF of my final working copy, but no version of Illustrator of it. Note that I have never created a PDF version of the book that I did at the end of the day. So technically the PDF file I have on my system should have only one I sent earlier in the day.

What possibly could happen here? I'm a little upset that I lost 8 working hours. But more important, I want to know what I did so that I wouldn't do it again.

Thanks for your help!

GS,

For safety, you always save a copy in PDF of Ouedraogo and stay at Illy, or save normally before save you to PDF and then close the document in order to avoid this trap.

You saved the file PDF without having checked preserve Illustrator editing functions, which means that the document is only saved in the possibly simplified PDF version.

Save as PDF with preserve Illustrator editing capabilities ticked, or save as to create a PDF Compatible is TICKING, you actually save two files complete, an AI and a single PDF.

You can recreate the document HAVE entirely or partially of the PDF, according to the work, by opening it to Illy and maybe redo parts. Some aspects of the work are the same, some are simplified in the PDF file.

  • Why have I lost all CD imported from my iTunes library

    I lost all my imported CDs and all the selections of my iTunes library painstakingly compiled over the years of effort. More than 110 GB of music disappeared from one day to the next day when I upgraded the software at the end of 2015. How can I get these without restarting the whole process again? The only thing left in my library is the purchased Playlist. Can someone help, please? Thank you.

    On some occasions, your iTunes library database may be affected by an iTunes update - nobody seems to know exactly why, although its been suggested that it would be the result of a conflict between the installation of iTunes and some anti-virus software program or other processes that monitor changes to files on your computer (for example the Windows Indexing service').  The content of your library, i.e. the media files and folders should be affected, but without a database iTunes file doesn't have information or links to these files.

    To restore your library to a working state (which may not be necessarily as it was immediately before installing the update) see user turingtest2 on the empty/corrupted after upgrade/crash iTunes library.  For later use, you must create and maintain a backup of your library iTunes, and always update your backup before installing the iTunes update.  For a suitable and recommended method, see backup your iTunes for Windows with SyncToy library .

  • Why have I lost all my favorites sync on my computer?

    I came back to work on Monday and all my favorites have disappeared. Recently, synchronize bookmarks on the new computer with the old computer. Bookmarks have been synchronized successfully... then I erased everything on the old computer. Where are my favorites?

    You should have turned off Sync on the old PC before you delete the bookmarks on the old PC.

    You should have a backup on the new PC which can be restored.

  • Why have I lost 400 emails.

    Why have I lost 400 emails.  Last night I had about 523 emails.  Before my eyes, it changed to 123.  What happedned where they went.  They were emails that I haven't read.  They could be important.  That's happened?  How to make a comeback.  Where did they go?  It was in outlook express.

    OE reviews | Current view | Show all messages (check/enable)

    Cautions general OE:

    N ' not use Inbox or sent items to archive messages.  Move them to local folders created for this purpose.

    -Empty the deleted items folder daily.

    -Frequently perform a manual compact of all OE while records that "work offline".  More onhttp://www.insideoe.com/files/maintain.htm

    -Do not cancel automatic compacting, where it would happen and do not try to close OE via Manager tasks or stop your Automatic compaction machine can take place.

    -Disable e-mail scanning in your antivirus application.  It can cause corruption (i.e., loss of messages) and offers no additional protection:

  • Restored Firefox with extensions disabled. Have I lost all my extensions?

    So I was testing my Firefox with extensions disabled when I clicked on 'Restore Firefox' by mistake. Have I lost all my extensions because of this? Apparently I still have my passwords, history and even cookies, but I got a lot of extensions that are now gone.

    Is it possible to recover?

    The extensions are removed during the update. Check the 'old data Firefox' that has been placed on the desktop.

    More information about the update is here.

  • My computer crashed and it restarted I asked me to refresh Firefox. I have now lost all my favorites etc. There is no 'old Firefox data' folder - help!

    My computer crashed (blue screen) and when it restarted a box came asking me to update Firefox. I clicked on OK (thought he was just trying to restore the session) and I have now lost all my favorites, passwords registered etc. There is no 'old Firefox data' folder anywhere on my system - help! is there a way I can get it all back without doing a system restore? I am running Windows 7.

    Hi, you can try it for only bookmarks: first open the bookmarks > show all bookmarks > import and backup > restore and see if you have a backup there.

    If not and the other favorites, please see.

  • Why did I lost all of my boxes in Yahoo mail?

    Hello, recently my Yahoo Mail went bonkers and I lost all of my boxes. You know the ones that I would use to check what emails I would delete etc, etc. It looks good on my other computers and on this computer through Google chrome.

    Have you noticed any other oddities on Yahoo mail, such as cans of high with two rows of two characters? This can occur when the site requires a downloadable font for its icons and you block that by using these settings:

    (1) in the dialog box fonts Advanced, unchecking the checkbox which allows the site to use its own choice of fonts. To check that:

    "3-bar" menu button (or tools) > Options > content > button "Advanced".

    Here you must "allow pages to choose their own fonts.

    (2) on the deactivation of fonts downloaded in: config. It's less likely, or you remember probably not, but here's how to check on it.

    • In a new tab, type or paste Subject: config in the address bar and press ENTER. Click on the button promising to be careful.
    • In the search box at the top of the list, type or paste the gfx and make a pause so that the list is filtered
    • If gfx.downloadable_fonts.enabled preference is bold and user, set false, double-click it to return it true.

    This seems useful.

  • Upgrade to Microsoft 2010 and have now lost all my Outlook Express emails!

    Hello

    Yesterday, I upgraded my pc from 2007 to 2010 from microsoft, I had no idea that outlook express is no longer taken in charge & a so don't had not saved anything express before the upgrade.

    I used two Outlook + outlook express to run 2 separate email accounts.  How Outlook works well and moved all my old mails/contacts.  Express however is not found, I can't open it.

    I have installation the other account on the new perspectives, he transferred the emails from the last 30 days, which lie on the mail server, but nothing beyond that, plus all of my files are missing & what is the most important!

    Please help me, I got hundreds of emails that are very important to me and I am in despair that they have all been lost.

    Thank you, Emma

    If you use Windows XP (which I assume you're OE does not work on any latest system) then by installing Office does NOT remove Outlook Express.

    He can't because Outlook Express is part of Internet Explorer, which is part of Windows.

    I think that Outlook has replced just the icon of EO for mail.

    Do a search for msimn.exe

    You should find it in c:\program files\outlook express.

    Then you can add back a shortcut on your desktop.

  • Why have I not all of these directories in C:\0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,f

    Hi, this confused me - partly because it is difficult to search on. So I think that some good old fashioned eyeballs have a much better chance to solve this mystery than a search engine! I upgraded this Windows 7 machine to Windows 7 Pro a few months back - 18/09/2013 to be exact. Please see screenshot below. I don't know if it's relevant, but it seems that more than a coincidence that, at some point during the upgrade, all of these directories have been created. Anyone know why they were Setup, what are they, and they are still needed? Any ideas would be much appreciated. Thanks for reading and have a nice day!

    My apologies for the delay absurd to update this thread!

    Two weeks after posting here, I discovered that records have been created by a data backup program secure whose parameters I had tweaked inadvertently, causing its work files should be stored in C:\ instead of their habitual residence.

  • Why have I lost icon paperclip on the Windows Mail Preview pane, and font is changed?

    I suddenly lost the paper clip icon in the right corner of the Windows mail preview pane, and details giving email policies changed. Now I can't click the icon to see the attachments, but must open the e-mail and view attachments in this way.

    Migration to Windows Live Mail is a possibility, Yes, but you must know that all is not necessarily well with IE9 installed either in Windows Live Mail: see http://answers.microsoft.com/thread/82750b30-a346-e011-9575-d8d385dcbb12

    Support for IE8 will continue as long as the version of Windows, in which he is running is guaranteed (and support for Win7 will continue for many, many years until more recently released Service Pack is installed).

    Same fo WinXP SP3 (and IE6, IE7 & IE8) Extended Support will continue until April 2014.

    If the icon available in the preview pane trombone is so important to you, stay with IE8 in the foreseeable future.

    And note that the attachments are always accessible in Windows Mail w/IE9 installed once you open the message. And if "read all messages in plain text" is turned on, the "bug of police" will not appear either.
