Data file
What is a .ent file?
A .ent file is a SGML/XML Entity File. This is a data file — structured information used by a program rather than read directly.
How to open a .ent file
- Start with the program that produced it; that's almost always the right tool.
- Open it in a text editor to see whether it's readable text or binary.
- For database formats, DB Browser for SQLite or LibreOffice Base can often import it.
The registry records this extension against SGML/XML Entity File, so software from that family is the most likely match.
How to convert a .ent file
- If you can view the data, exporting to .csv is usually the most portable option.
