# On-prem Files
This connector lets you integrate with files within a secure network. These files typically are behind a corporate firewall and cannot be accessed directly. To create a connection to on-prem files, you must use an On-prem agent.
Workato's On-prem files connector allows you to securely connect to those on-premises files and build automation around them.
# How to connect to on-prem files on Workato
Before creating a connection for this connector, make sure you go through an on-prem agent setup and create a profile for on-prem files.
On-prem files connection using on-prem agent
| Field | Description |
|---|---|
| Connection name | Give this On-prem files connection a unique name that identifies which On-prem files instance it is connected to. |
| On-prem connection profile | Name of the profile you wish to connect to. This should be defined in your config.yml file in your On-prem agent. |
| Is this app in a private network? | Select the on-prem agent that you setup earlier. |
# Working with the On-prem files connector
# Relative path
Relative path is a way to specify the location of a file or folder based on the location of another folder. This is different from absolute path where you specify the full location of a file.
File or folder path in the on-prem files connector are all relative paths. It is relative to the base path you define in the connection profile of your config.yml file. Let's take a look at an example.
Here, we have a profile with the base path defined as the /Users/admin/projects folder using the base property.
files:
projects:
base: /Users/admin/projects
Now, if you wish to point to a file in this sub-folder /Users/admin/projects/engineering/2018_roadmap.csv, you will have to use the relative path /engineering/2018_roadmap.csv. When used in a download file action, it will look like this.
Download content from file path
Similarly, to point to a sub-folder /Users/admin/projects/marketing/users, use the relative path /marketing/users.

# Naming pattern
Frequently, you may have a log of multiple files with a naming convention. These names typically either includes an incremental count to represent the versions or timestamp to represent the effective date of the contents. Defining a naming pattern allows you to filter files based on these naming conventions. Workato uses the ? and * symbols to represent any single character or multiple characters respectively.
# Single character wildcard ?
The ? symbol is used to represent any character once. For example, Report_draft_?.pdf can be used to represent Report_draft_1.pdf, Report_draft_2.pdf and Report_draft_3.pdf.
# Multiple character wildcard *
The * symbol is used to represent any zero or more characters. For example, Report_draft*.pdf can be used to represent Report_draft.pdf, Report_draft_1.pdf, Report_draft_2.pdf and Report_draft_3.pdf.
# Using naming pattern in a recipe
Let's look at an example of a marketing manager who needs to work with a folder that contains a few type of information series of webinar.
📂 Marketing
- 📂 ProductHour
- 📄 Attendees_2018_11_29.csv
- 📄 Attendees_2018_11_15.csv
- 📄 Attendees_2018_11_01.csv
- 📋 Poll_responses_2018_11_29.txt
- 📋 Poll_responses_2018_11_15.txt
- 📋 Poll_responses_2018_11_01.txt
- 📊 Slides_2018_11_29.pptx
- 📊 Slides_2018_11_15.pptx
- 📊 Slides_2018_11_01.pptx
Based on each use case, files from this folder can be filtered in a number of ways.
| Use case | Naming pattern | Usage |
|---|---|---|
| Trigger on CSV lines in Attendees information | Attendees*.csv |  Filter Attendees CSV files in a trigger |
| List only Poll responses files from November | Poll_reponses_2018_11_??.txt |  Filter Poll responses from November |
| Trigger on new Presentation slides in 2018 | Slides_2018*.pptx |  Filter Presentation slides |
