Error Message - Could not open "filename.psd" because the file was not found.

Since I have not heard anything in several days I wanted to give an update... We have now found our problem is in relation to any file that we have created as a template in Photoshop using stock images in smart objects.

From our own internal efforts, we suspect this issue may be stemming from security software seeing something suspicious about these files. At present we have not been able to confirm this, but we are testing the theory on Mac's outside of our office environment/security measures. However, if that turns out to be the case, it may be an issue that Adobe should look into.

It also seems that Photoshop Droplets may be seen as suspicious by certain security software as well because the Droplets origin may not be verifiable.

That is good information. However, the original file in question was not saved to the server, but copied to the server after it was created. Each of us then made copies of the file on the server to our computers to use as a template file. None of us save to the server. We work on our computers and copy to the server.

I understand that. The point is that saving directly to a server (or any network connection) has a very high risk of file corruption. That is why it is unsupported and warned against by Adobe.

The correct, supported way is to copy the file to local drive, do the work and save locally, then copy the finished file back to the server.

Once a file is corrupted by one network save gone wrong, it will naturally remain corrupt for future users even if they fetch the file in the recommended way.

The original is on the server. Each of us has a copy of the original. We can make a new copy at any time if we need it. New copies of the original files do the same thing.

Is this file on a server? Was it at any point saved directly to the server?

No, Photoshop did not crash the last time I used the file. This is a template file, in that we created it last March and all of our designers get a copy of it. We then swap out product images inside it to create product samples. All of us (8 designers/8 different copies of the same psd) get the same error with our copy of this file. It is one of 10 that we use for this product type, the only one producing this error, and the only one with an image in it (aside from our product). 

** could not see how to attach a text file.

Not sure if a video would help, it's an error that occurs when trying to open a specific .psd file (see screencap below). We aren't certain that the problem is with the Adobe Stock image, but that is the part of the file that was not created in the file. The image is not linked so there should not be an issue if the original image or the .psd is moved to a new location. However, the error saying "the file was not found" is confusing.

Hey @Dan34553834wpif!

I'm not sure if I understood correctly. Could you provide more details or share a short video? Is the issue with a smart object from Adobe Stock that couldn't be loaded because the file is missing, or is it happening with files you have stored locally? Did you move the file to a different location previously?

Thanks!
