No, the update has nothing to do with this.
Some other application on your system has that file open, so it can't be saved over.
Photoshop is just letting you know that some other application is holding the file open, and that Photoshop cannot save over the file until that other application let's go of the file.
That's not it... I have obviously thought of that. And this error never started occurring until I updated photoshop this week. I have no other applications running that use the file. I am not doing anything different than I have done for years now with editing and saving files with photoshop.
That's not it... I have obviously thought of that.
No, that is it entirely.
You have the Windows Explorer running, anti-virus (I hope), and lots of other little services -- any of which could have a problem and keep files held open longer than they should.
I'm having the same problem this week as well. I've been using
photoshop for years and I've never had to close windows explorer
in order to save a file. This is definitely a new glitch.
Turn off Caching of Thumbnails in Hidden thumbs.db Files
People sometimes report that they cannot manipulate their folders as they want to because Explorer has a thumbs.db file open. Windows 7 apparently generates these files for compatibility with older software that may expect such files to exist in folders with, for example, photos in them.
The good news is that (with Windows 7 Professional and above) you can disable this through the Group Policy editor:
- Click the Start orb
- Enter gpedit.msc in the search box and hit Enter.
- Expand User Configuration - Administrative Templates - Windows Components.
- Click on Windows Explorer.
- Right-click the entry "Turn off the caching of thumbnails in hidden thumbs.db files" and choose Edit.
- Enable the setting.
