I have a weird issue I’ve been dealing with for the past couple days. I’m using a file upload component to upload a file onto a server (bypassing a horrible file upload interface in a web application). The filename is of this format: `//SERVER-NAME/Path/filename.pdf` where `filename.pdf` is the name of the uploaded file. The UNC path `//SERVER-NAME/Path` is added to the `ignition.conf` file. I tried to run a simple script in the Script console to troubleshoot, but the file wrote successfully from the Script Console. Here is the sample script which worked correctly: ```auto bytes = bytearray(b'HELLO WORLD') filename = '//SERVER-NAME/Path/testdoc.pdf' system.file.writeFile(filename, bytes) ``` I don’t know why a button press doesn’t yield the same result. When I log the exception that is thrown, it says ```auto "File '//SERVER-NAME/Path/testdoc.pdf' doesn't exist or isn't a file" ``` What could be the problem? ---

If it’s running on a _Perspective_ button the big difference is that when executed in the script console it’s running on your computer as your user in the Designer process, and when executed from a button press it’s executing on the gateway as whatever user the Ignition service uses. ---

So then the issue is likely how I [added a network path](https://docs.inductiveautomation.com/display/DOC80/Mapping+a+Network+Drive) to `ignition.conf`, right? ---

Yes, probably something to do with that. ---

I’m looking in the `wrapper.log` file and I see the message ```auto Unable to create path to file '//10.1.20.11/Blinfo/Links/REQUISITION_QUOTES/filename.pdf' ``` What does this error message mean? ---

Seems like a permissions issue. Whoever is trying to write filename.pdf doesn’t have permissions on that network share to create the specified path. ```auto //10.1.20.11/Blinfo/Links/REQUISITION_QUOTES/filename.pdf ``` ---

That isn’t necessarily true… End users don’t write to the share if they use a Perspective session (with a button and a file upload component). The server that hosts Ignition will write to the remote directory. I added authentication for the file share to the `ignition.conf` file and made sure the folder permissions were set correctly. I also made sure to share the directory with the user I added (and made sure the user / password combination was still valid). That is what I understand from reading the docs, I may be incorrect. ---

Maybe this doesn’t matter, but shouldn’t all those forward slashes be back slashes? and what logger was responsible for that error message? ---

> [@code\_skin](#): > > @paul-griffith; could you confirm this edit? I'm pretty sure it's one or the other, yeah. For what it's worth, I've always had more success using the wrapper args approach - theoretically making the service run as a user should give it permissions, but I haven't had a lot of luck with that. ---

Here is the `ignition.conf` entry I added: ```auto wrapper.share.2.location=\\10.1.20.11\Blinfo\Links wrapper.share.2.target=P: wrapper.share.2.type=DISK wrapper.ntservice.account=\ wrapper.ntservice.password= wrapper.share.2.account=\ wrapper.share.2.password= ``` Here is (essentially) how I use system.file.writeFile(): ```auto bytes = bytearray(b'HELLO WORLD') # bytes is an uploaded file # Notice how REQUISITION_QUOTES is a subdirectory of `Blinfo/Links` filename = '//10.1.20.11/Blinfo/Links/REQUISITION_QUOTES/' # What else I tried # filename = 'P:/REQUISITION_QUOTES/' system.file.writeFile(filename, bytes) ``` Maybe it will serve me well to stop and start the Ignition service. As you can imagine, this isn’t the best option. ---

If you never restarted it after adding those entries then there is no chance they will have been in effect. Also consider the forward vs back slashes. ---

I did stop and start it before, but that was a while ago. Nothing has changed since then, but I might wait for a break to restart it. Regarding the slashes, I use forward slashes singularly and if I use back slashes, they’re doubled up (because the first one escapes the character that follows it). I tried almost every combination. Also, something I forgot to mention is that I can go to the Explorer on the Ignition server and I can put in `\\10.1.20.11\Blinfo\Links` and browse the folder. So it is reachable and the directory is shared. ---

Restarted the service and now working again… Thanks Kevin
