There is a registry hack you can apply to do this.
Copy and paste the following into a text file and then save is as Fix.reg. Then launch the Fix.reg file.
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Jet\3.5\ISAM Formats\Text]
"ExportFilter"="Text Files (*.*)"
"ImportFilter"="Text Files (*.*)"
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Jet\4.0\Engines\Text]
"DisabledExtensions"=""
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Jet\4.0\ISAM Formats\Text]
"ExportFilter"="Text Files (*.*)"
"ImportFilter"="Text Files (*.*)"
The following will reverse the changes, if you decide to:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Jet\3.5\ISAM Formats\Text]
"ExportFilter"="Text Files (*.txt;*.csv;*.tab;*.asc)"
"ImportFilter"="Text Files (*.txt;*.csv;*.tab;*.asc)"
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Jet\4.0\Engines\Text]
"DisabledExtensions"="!txt,csv,tab,asc,tmp,htm,html"
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Jet\4.0\ISAM Formats\Text]
"ExportFilter"="Text Files (*.txt;*.csv;*.tab;*.asc)"
"ImportFilter"="Text Files (*.txt;*.csv;*.tab;*.asc)"
