File Type Analyzer tool not detecting file types

Products

Issue/Introduction

File type filter isn't working in DLP 16.0. I need to use File Type Analyzer to see the file signature.

Error: There was an error processing your request. Please check logs for more details.

Environment

DLP 16.0

File Type Analyzer

Cause

File Name Filter does not contain the correct syntax to match on file names.

Resolution

File Name FIlter syntax can be found here, Creating a data set.

Examples:

The following regular expression reads in all ASCII file names from a directory (or directories) to a data set:
[\w\s]+.[\w]+
The following regular expression lets you filter file the names that use non-ASCII characters:
[^0x00]+.[\w]+
