When opening the Data tab for any table in the Object Explorer, a temp file is created in the directory: C:\Users\username\AppData\Local\Temp
If the option Database | General | Number of rows fetched = "Unlimited" is set, this will return all rows inside a table.
For tables with thousands or millions of rows, the temp files can grow to several GB in size.
These files are not deleted from the above directory when Toad is closed.
