Simple Delimited Text file types have the following extensions: *.txt and *.csv.
Configuring Simple Delimited Text file types Specify how SDL Trados Studio extracts and displays text from files processed with the Comma Delimited Text file type, Tab Delimited Text file type, or any new Simple Delimited Text file type that you create.
Example: Structuring a Simple Delimited Text file Specify a structure applicable to a file which contains two columns separated by custom delimiting characters. This ensures that SDL Trados Studio processes the first column as the source text and the second column as the translated text.
