Hi all, i have a scheduled Gateway Event Script as below:  
 ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/f/1/f1b9553fc6738316f6d6a223ed89c194b17d90e9.png)

```auto
def dataExport():
	#query data
	data = system.db.runNamedQuery(something)
	
	#export to csv
	csvData = system.dataset.toCSV(data)
	
	#check if folder exist
	folderPath = "C:\\test"
	if system.file.fileExists(folderPath):
		#export file
		filePath = folderPath + "\\some_exported_file.csv"
		system.file.writeFile(filePath, csvData)		
	else:
		dummy = 1

```

Now, the file is able to export, but at the same time i am getting error:

Many thanks in advance!

I presume you're looking for this folder on your gateway and not locally?

@nminchin How can you open a file on the server where the gateway is installed?

From where? Perspective? Vision? Gateway script?

Perspective and gateway/tag script are all run in the gateway scope, so you can just use the normal python methods with the `os` library

```auto
for (dirPath, dirs, files) in os.walk(filePath):
   print files
   break

```

from memory will walk recursively through a folder. Break it after the first run to make it not recursive

Or just don't put it in a loop.

```python
root, dirs, files = next(os.walk('path'))

```

alternatively, you could use `os.listdir`, which returns everything that's at the specified path.  
You can filter for files only with `isfile()`, which you can import from `os.path`

```python
from os import listdir
from os.path import isfile, join

files = [f for f in os.listdir(path) if isfile(join(path, f))]

```

From Vision it's trickier. However the easiest method is to create a fileshare and access the files using the UNC path to it

You can use `system.util.sendRequest()` to message a handler in the gateway. Such a handler can open a file for you and return the bytes. Then assign those bytes to the PDF Viewer.

I have solved it using this manual [Storing Files in a Database - Ignition User Manual 8.1 - Ignition Documentation](https://docs.inductiveautomation.com/display/DOC81/Storing+Files+in+a+Database)
