How delete blocked SHX comments

How can I delete blocked SHX comments? File saved from AutoCAD

[try67]

You have to unlock them first. Right-click it, select Properties and untick the Locked check-box.

Thank you for taking the time to my questions, but the problem is that the Comment is not blocked. The checkbox is empty in the properties, I conclude that AutoCAD does this when converting to PDF.

Can you share a sample file with us?

You can use this free tool I've developed to unlock them: http://try67.blogspot.com/2016/12/acrobatreader-unlock-all-comments-free.html

Many thanks! I downloaded and installed the script for you, it works. But unfortunately, very slowly, even in the example file, with a small number of blocked comments, 450 comments in 4 minutes. Usually, I need to delete 6000-7000 thousand comments.

I'm implemented some changes that should help it go faster. Download it from the same location and try it again.

[Dmitriy K.]

Yes, it works instantly! Awesome, thank you very much.
I tried to add a delete all comments

annots[i].delete;

it didn't work, can you tell me the correct code?

[try67]

Actually, it's: annots[i].destroy();

But it might not work because of the type of loop I'm using there.

Replace this part of the code:

for (var i in annots) {
annots[i].setProps({readOnly: false, lock: false});
}

With this:

for (var i=annots.length-1; i>=0; i--) {
annots[i].setProps({readOnly: false, lock: false});

annots[i].destroy();
}

[Dmitriy K.]

Ideally! thank you so much! The last question: IS IT POSSIBLE TO DELETE BY FILTER, only those comments that have Test in the THEMA properties?

[try67]

It's not possible to know which comments are displayed and which are not, no. It is possible to manually filter them in the script itself, based on various criteria.

[Dmitriy K.]

Happened!

for (var i=annots.length-1; i>=0; i--) {
annots[i].setProps({readOnly: false, lock: false});
if (annots[i].author == "AutoCAD SHX Text")
annots[i].destroy();
}

Once again, thanks a lot!

This solution works where all others fail to remove to SXH Text Comments. When they number in the thousands, they are the most common cause of Acrobat memory leaks and program crashs. Thank you!
