File not found error when opening an ai file.

[MotoJoe]

When I recently switched computers to work at home, I put all my files in Adobe Creative Cloud.  When working at home I download the file and open... However some files show as do you want to replace as it cannot be found.  

Why is this happening on all my files?

When you placed your images into this project, you likely created a link to the original location of those files. So, even though you moved your Illustrator document, you either didn't also move the associated files, or changed their relative location to the original. To fix this, either embed your placed files, or create a package. This creates a new folder with all your linked files, and changes Illustrator's information on their relative position in the file system. To learn about packaging, see this article:

Thank you for the further information.  I will need to change the way I save files moving forward. TY

This is great to know, thank you! Is there any way to embed the files post hoc? I don't have access to some of the images in my ai file anymore but I need to edit the ai file. Everytime I open it it reduces the resolution of the images that it cannot find (I assume it is just using the thumbnails it created of them as placeholders). I have a PDF version that opens fine in acrobat but when I open it in illustrator it does the same thing.

Try to open the PDF file in Photoshop in the Import dialog select Images and save them to relink/embed them in Illustrator.

That worked! Thank you so much!
