TSV File Format

Tab-separated values file

TSV is a file extension for a tab-delimited file used with spreadsheet software. TSV stands for Tab Separated Values. TSV files are used for raw data and can be imported into and exported from spreadsheet software. TSV files are essentially text files, and the raw data can be viewed by text editors, though they are often used when moving raw data between spreadsheets.

I noticed a file appeared on my desktop a few weeks ago. It is: "IEU27COI_source_data"
Apparently, it's a .tsv file. When I Google it, I get "0" results! Does anyone know what this is? Is it malicious? 
Thanks!
