By default the following file extensions (.txt .doc .xls .ppt .java .c cpp .h .js) will retain their original file type when Quarantined and replaced with a marker file.
To adjust the file marker extension that is left in place of a file that has been quarantined you will need to modify the following file on your Network Discover server: ProtectRemediation.properties
ProtectRemediation.properties is located in \Vontu\Protect\config (/opt/Vontu/Protect/config for Linux)
Modify the following line: com.vontu.protect.extensions_not_replaced=txt|doc|xls|ppt|java|c|cpp|h|jsExample if you want all replaced marker files to be filename.doc.txt OR filename.ppt.txt
To complete the change, save the file, then Restart the Vontu Monitor service.
