From your torrent client, do also an export of all your current seeding torrents, it will also give you a list of all your torrent names, paste those also in a new Tab in Excel.

In Sheet1 you should have all your FTP names in column 1 and on Sheet2 you should have all your seeding torrents name.

In Sheet1 you should then do a VLOOKUP against Sheet1,Row1,Column against Sheet2, Row1:Row"Where It Ends".

An example of the vlookup command should be something like this on Sheet1,Column3, Row1: =IFERROR(VLOOKUP(A1,Sheet2!A$1:A20000,1,FALSE),"To rrent Deleted")

Thus, if a torrent name is not found from your FTP list against your seeding list on Sheet2, it will mark it with "Torrent Deleted", else, if it is still seeding, it will show the torrent name.

I hope this helps

I was about to suggest something similar to what SpiderCrawler did.
It it probably the wisest thing to do.

Another thing that might work is to create a new folder inside your “files” folder. Name it 00 for example.
Than select all your torrents from rutorrent and use “save to” option and transfer everything into this new folder.

Whatever is left on the original folder is something that is not active in your client.

Downsides:
If you are an organized person and likes to keep everything on folders, you will lose it.
Your client might crash a couple times if you try to do it on a large quantity of torrents at the same time.
