EFT can block the upload or download of certain files. You can specify which files to block using wildcards or exact file names.
For example, to block a file called virus.wav, you can type any of the following:
(blocks the specific file)
(blocks all wav files)
(blocks all files whose extension starts with wa)
Take extra care when using wildcards to block files so that you do not block files that you want to allow.
To ban files
In the administration interface, connect to EFT and click the Server tab.
On the Server tab, click the Site you want to configure.
In the right pane, click the Security tab.
In the Data Security area, next to Banned file types, click Configure. The Banned File Types dialog box appears.
Select the Exclude the following files from the Site check box, then type the filename or wildcard representation (*.mp3 or *.mp?) for the file(s) you want to exclude from the Site. Separate multiple entries with commas.
Click OK to close the dialog box.
Click Apply to save the changes on EFT.
