This just started today! I seem to have lost a couple of days work in Illustrator! I can't see the files but when I tried to copy a file of the same name into the same folder "It asked if I wanted to replace the file" BUT the file doesn't show up at all and I can't see it!!! Also can't seem to save into that folder!! HELP ANY ONE!!!!!
What is the file path of the folder?
It's a external HD
If you navigate to that location in the Finder/Windows Explorer, the files are not there?
No they are not.
Can you copy the file to your internal disk using the system's interface?
What is the name of the files? Does it contain any non-latin letters?
Is your disk working? Have you checked it?
Illustrator has issues with external disks. Does it work saving to your harddisk?
And also: which system and Illustrator version is it?
