Create new project: "File already exists" (it doesn't)

[JSome.2]

When I attempt to create a new project with TouchGFX Designer 4.18.0 using the STM32F469I Discovery as a board setup, the Create button gets to 88% and then consistently fails with the message "Error: Cannot create a file when that file already exists."

The message seems completely misleading though. It also asks me to look at the TouchGFXDesigner.log for additional info. That log tells a completely different story. Roughtly halfway through the logfile, I find:

followed by roughly one metric ton of .NET exceptions.

Also note the message: "Take operation was canceled." This is not a manual cancellation by me. Once I started the project generation, I did not interact with Designer again. The message appears to refer to an internal or self-cancelation of some sort.

If there is a timeout, it's an incredibly short one. The generation process gets from 0% to 88% in just a few seconds, and then the error happens within subsecond time of reaching 88%.

Suggestions?

Hi,

Could you share your log file so that I can forward it to the TouchGFX Designer team ? Could you try to change the name of the project you are trying to create to something different to the standard MyApplication_x ?

Thank you for answering so promptly, Romain. I will attach my logfile here.

I see where at least part of my confusion comes from. Looking at the timestamps, this logfile was not created when I generated my project. It's a cumulative logfile of everything Designer has done since I installed it yesterday.

I reproduced the error using the project name EmptyTestProject. I notice that if I create the project on a local drive, project creation works fine, but if I create it on a shared drive (as in this case), the error occurs. I've only done this 2 or 3 times but I am pretty confident there's a correlation there.

I am experiencing the same problem with V4.22.0 when I create a STM32H747I-DISCO project on a shared drive.
The project creates successfully on C: drive with no error messages, but every time I try to create it on a shared drive I get the "File already exists" error.

The relevant section from the log file:

This is an issue for users which use virtual machines. In my case, I run GFXDesigner on a Win10 virtual machine and the the CubeIDE is running natively on macOS.

It would be great if the developers could resolve this issue to enable the use of shared drives and thereby the use of task oriented VM's.

Hello @helioz,

I just created a project on a shared drive, without any issues.

Does that happen only while using VM or also on a classic Windows 10 setup ?

[CTapp.1]

I've just run into this when trying to create the projected in a shared folder under VMware Fusion on Mac.

Looks like creating the project on a local drive and then moving to the share works.

[Andrei Chichak]

Yes, end of 2025, issue still exists.

Create a project on a shared folder or network drive (z:) and you get a misleading file already exists message.

VMware Fusion on Mac.
