I'm creating a custom IFilter for sqlserver, for a my extension (we can call it "abc"). The abc files are generic crypted files, that have originally a different extension and that are recorded in a sqlserver filetable. When I copy a file into my filetable, I crypt the file, I changhe the extension in abc and I record the original extension in another table of same db. When my IFilter starts, it receives a file with abc extension but his name is created by sqlserver and it doesn't have any connection with the name of the file stored in filetable. If I could retrieve, from that name, the record in filetable, then my problem would be solved.
Thanks in advance Luigi
