# Setting Application Types for Filetype Extensions

# Introduction

Configure filetype_extensions.map to set the application types for filetype extensions.

Apply the configurations shown in the Open iT server.

# Configuring `filetype_extensions.map`

Open filetype_extensions.map in the Configuration directory, which is by default in C:\Program Files\OpeniT\Core\Configuration.

Notice that it contains instructions on how to edit the file.
Specify filetype extensions with the following syntax:
Mapping Syntax
```
MAP: ApplicationName    
FiletypeExtension1      
FiletypeExtension2 
```
Empty lines are allowed — any line beginning with # as the first non-whitespace character is considered a comment. Globbing is also supported, allowing you to use several globbing patterns; however, remember that they are slower than exact matches. To make your mapping files more effective and efficient, refer to the Optimize Rules to Speed-up Rename or Mapping page.

In the mapping file, entries are case-insensitive, meaning that capitalization variations, such as 'PNG' and 'png', will be recognized as identical. Also, note that leading and trailing spaces are removed from entries.

By default, the most common filetype extensions are already included in this mapping file.
Example
```
MAP: animation    
mpe
mpeg
mpg
pcs
```
This example maps mpe, mpeg, mpg and pcs filetype extensions to animation.

You can also include custom configurations in this mapping file, such as default mapping, setting date limits on specific mapping entries, or creating nested maps.
Save the changes.

The mapping file will only affect the data collected after configuring. To apply the mapping for historical data, you need to regenerate that data. This process will help ensure that all your information is aligned and accurate.

Open filetype_extensions.map in the etc directory, which is by default in /var/opt/openit/etc.
