Customizing File Types


You may create your own known file types and add their file signatures for scanning in Known File Types. They will appear in their respective folders on the File Types dialog box.

You can do that either by using the R‑Studio's graphic interface or by direct editing the known file description file specified on the R‑Studio Main settings dialog box.

Creating a Known File Types using a Graphic User's Interface

To create a Known File Type,

TXT_ANSI : The file can be viewed as ANSI text. If this flag is specified, the file can be correctly represented as an ANSI text. When previewing, this file will be immediately sent to Text/​hexadecimal editor .

TXT_UNICODE : The file can be viewed as UNICODE text. If this flag is specified, the file can be correctly represented as a UNICODE text. When previewing, this file will be immediately sent to Text/​hexadecimal editor .

From

A decimal number specifying the leftmost possible offset for the file signature.
