Yes: in the full version of TGTools, you can delete unused expressions

Bare in mind the full version of TG Tools is not included with Finale and it is not free. It is an extra cost option.

Have you tried the Expression menu and used the delete option?

It will then ask you two options for you to choose.

thanks, but Tgtools leave some expression behind...safer the longer method!

I think the OP was asking about mass deleting all unused expressions. The TGT plugin (yes, it's an additional cost, but hey, so is PL [which can be 2x the cost of TGT]) does this handily. For deleting a small number of unused expressions (and you have to hope you haven't used it), you can do it in the Expression tool but TGT is better.

I investigate better...

 I have nothing against anyone wanting to add TG Tools or Patterson plug-ins. Just made mention that they are not free. Just like everything Finale a plug-in can not do what Finale can not do. And, you can delete Expressions in the Expressions menu.

However, TG Tools is not even in the same zip code as Perfect Layout and can not be compared.

I'm always impressed by your devotion to Perfect Layout and willingness to serve as an evangelist for it. Kudos. My bad for even thinking TGT is worth mentioning in the same thread.

David why do I sense this hostility form you. The two are not comparable. They accomplish different things. You made mention that PL was not free for a whatever reason. It wasn't even part of the conversation. I use TG Tools. I use NP4. I use Patterson and I use Perfect Layout. They all do what I want but they are all different.

No hostility at all. I gave you a compliment and agreed with your comment.

I am, however, struck by how often and fervently you feel the need to bring up PL, but never the cost. Yet you specifically (and correctly) pointed out that TGT costs. I stated in my first comment that this functionality (deleting expressions en masse) is for the full version of TGT. That should have implied a cost associated with it. So in fairness, I also pointed out the PL is not free. That's all. I'm glad whenever anyone gives a shoutout to independent developers, including Patterson, JW, TGT etc. 

I have no interest in PL beyond it ability. It was not necessary for you to bring it up. Not everyone is aware there is even a full version of TG Tools available.

Well, now they do know about the full version of TGT ;-)

They... who are they?

please... I own Finale since version 3... with TGTools pro.

I confirm that TGT delete some unused expression AND leave some unused expression behind, where it was

Well that has not been my experience with TGT but whatever. Perhaps you should take it up with Tobias, who actually programs TGTools. But I just tested it myself and it behaved correctly.

"They" are everyone who reads this thread who somehow didn't already know.

ok, so your test is ok and they had another experience.

Tobias answer:
“Hello,
I am not sure, I think you should not use this feature. It was last tested 20 years ago.
Kind Regards,

Interesting…and sad. I think Tobias might want to update things. I rarely use TGT and even more rarely, that feature, but a few things are very useful on occasion and it would be a shame for it to languish.

 I rarely use TGT and even more rarely, that feature, ....

You might want to consider that before you advise folks.

Thanks for that snarky advice. I had found no issues with it but I guess it’s my fault for assuming a paid, released version works. 

But as always, thanks for your expert opinion, Biggs. You’re right; no point in my providing advice here. I’ll get back to my day job and leave it to you to do whatever it is you do. 

I propose to shift to a positive attitude:

would it be possible with Lua for instance or with some other script?

TIA
