Not able to open open a few psds, getting this error

 

Could not open “RAM5DC_LH_edit.psd” because the file is locked, you do not have necessary access permissions, or another program is using the file. Use the ‘Get Info’ command in the Finder to ensure the file is unlocked and you have permission to access the file. If the problem persists, save the document to a different file or duplicate it in the Finder.

 

What we tried for this error resolution - 

1. Gave photoshop full disk access under the preferences

2. The issue is only for a few files and if the file is copied to a different location on the same file server, the issue is resolved.

3. Update the Photoshop to the latest version.

Yes. All the time. It is because the server and Photoshop are still communicating and it thinks PS still has the file open.

If you are the only one accessing the file, do this as a test.

  1. Quit Photoshop
  2. Unmount the server share
  3. Remount the server
  4. Open the file

Does the error still occur?

If it doesn't that points directly to the read/write speed issues on your server and Photoshop. Hence why Adobe does not support working across a network.

Drag the files to your local HD and they should open.

Opening off a server via Photoshop is sketchy at best.

Between server permissions and read/write speed - the official Adobe position is to never work directly on a server.

Thanks for your response. I have always been able to open a .psd file from the server, it has never been an issue. I cannot possible drag every image I need to look at onto my desktop. If I have to work on it, yes I agree off the server is best. 

Has anyone had this warning come up?

My server connection is via thunderbolt 3 to an array that is way faster than any internal drive, with 8 disks giving me about 2 gigabytes per second (or 16 gbits per second). So speed is not the issue, it's photoshop programming. My photoshop files are around 1.5Gb and have many linked psd's and psb's, so this is not possible to move files to my local drive for editing and move back when done, as the links reside in various folders. I'm also editing in Premiere Pro and After Effects all the time, and have no issues with those apps with file access. This is a serious fault from Adobe with photoshop, which never used to exist, as I've been on this current server setup for several years.

It's not just speed, it's different and unpredictable server configurations. Working directly off a server has never been supported by Adobe and is at your own risk.

 

You can bang your head against the wall and keep insisting it should work, or you can adjust your workflow to a safe procedure. We all have to do that. I deal with two different server setups at work and this is just a basic precaution.

This has been an issue since I've been working in the industry over 25 years ago. It's not a new issue that "never used to exist". Working directly off removeable media or network servers has never been supported by Adobe. I've learned the hard way to not do this by losing/corrupting files more than once.

I've been working with photoshop since the early 90's on version 1.0, although only on removeable media/ servers since 2005. Never had the problem until recently, in the last year.

You can usually get away with working directly to server - until you don't.

 

It has always been at your own risk. Nothing has changed.

I will say that it has gotten significantly worse since Mac OS Catalina for Mac users. Each update (Big Sur, Monterey) has increased the security and really screwed up our connections to servers.

I'm having the same issue.  I am working with a 2.66 GB Photoshop file.  I can work off from the server on my MacBook Pro (2015), but I can not work off the server with my recent purchase of the Mac Studio (2022).  The MacBook Pro and Mac Studio have Monterey 12.4.  The MacBook Pro has Photoshop 23.2.1.  The Mac Studio has Photoshop 23.3.2.  I tried opening other large files files on my Mac Studio and get the same "Could not open “[file name].psb” because the file is locked...".  This seems to point to the idea that Adobe is the problem and not Apple.  There seems to have been a programing change in the software somewhere between Photoshop 23.2.1 and 23.3.2.

Sorry this is solely an Apple issue as much as people want to point the finger at Adobe. The sheer size of that file would give me hesitation of working directly off a connected server. AFP and SMB protocols have become increasingly worse with each security update.

There are so many factors that affect connections - speed (incoming/outgoing), server usage, what type of drive, connection issues, etc.

It's so various and uncontrolled at scale that Adobe's official position is to not work directly off remote servers period.

If you truly believe it's just an Adobe issue do not attempt to work on Excel documents on a Mac from a Windows server with various users. It will corrupt.

There is no "fix" coming. This has been around for decades. It's the nature of the limitations of the physical hardware. Drag local, edit, save then drag back to backup on a server.

This has been an issue for literally decades. It works until it doesn't. I've seen it with pretty much every combination of Windows and Mac clients, with Windows, Mac, Linux, Solaris, and Netware servers. USUALLY you can work off a remote server but eventually, something breaks.
