acad 2002 vs. 2009 LT file size.

So here is the deal. In my old 2002 I have Superpurge installed, and that isn't compatible with LT versions.

After working on a file in 2009, I had all my setup objects in there and stuff. I delete everything I don't need any more and the file is at about 3.9MB. I do the purge that is built in to 09 and the size goes to 2.8MBish. I used LT extender to put in a LISP routine I have that is supposed to purge through even more stuff, and the file size goes down a bit more, around 2.4MB. I know I can do better.

I open the file up in 2002 and run Superpurge on it, and a couple more tools I've collected over time to clean up files, and the size goes to less than 400KB! Yes, it was like 380kb, a third of a megabyte.

So I open the file again in 2009 and simply hit save. The file size jumps from 380kb to 1.8MB just by opening and saving it!

What do you suppose that means? Is 09 just adding a bunch of junk it needs or what? Is there a Superpurge-type equivalent for LT? And if there are options in LT that increase file size by storing data I probably don't need to store, what sort of options are those and where can I turn them off.

What do you reckon?

Save As > AutoCAD 2000/2000LT.

The 2007+ File Format is different than the 2000 file format. You can set this as an autosave under Options. Try this and see if it does anything for you.

I am with you why do drawings swell ? there is obviously hidden data to do with Map civil3d, yes you can easily get a 3mb dwg down to say 500kb search the forum here for other posts containing suggestions. Its almost a question that needs to be directed to Autodesk "please explain".

This is what I am doing already!

I save that way due to sending to clients and such, as well is swapping back to 2002 when I need to.

I was actually wondering if the native 2009 latest format (or whatever latest is) might be better. I might try that.

Still looking for a 09 equivalent Superpurge.

So what's the need for saving 1MB-3MB of size each file?

I don't really worry about filesize myself. Just something that doesn't have any importance in my line of work. Sure I might get some big filesizes but that's usually after a BIND. Either way, when I send to customers, taking all the DWG's you're gonna send and making a *.ZIP file does wonders in furthering the compression for email purposes. Usually it's a 50% compression if not more, every single time.

Yes but I'm picky about the details. If a 3mb file can be 405Kb just by running Superpurge, I have to wonder why there is all the junk in there, and that bugs me enough to where I want to purge every file.

The other point is that we have our whole back-log of work archived, so it's a simple matter of saving gigabytes of space over thousands of files.

We always zip the files to E-mail, but if I can purge everything this small, I can zip up 12 sheets to less than 1mb. Sometimes we have a job to send at closer to 20 files, and I like to keep attachments less than 5mb so they don't bounce from some servers out there. I also assume the files will open and run faster when purged that small, but maybe I'm wrong on that.

So it's just a nit-pick thing? Cool.

I guess LT is your ultimate problem then.

I have a similar problem. the base file I had dreceived from client was 4 MB. it contained 20 layouts. when I resave it, it goes to around 30 mb in size. .

you said when you resave it in full version 2002, it is reducing but its not happening in my case. when i send it to thme they save it in 2006 full version & it still remains this big. any ideas?

The reason I get files so small in 2002 is because I use one program addon and two special lisp utilities.

I run Superpurge on the files. This is AFTER I make sure there are no extra layouts/viewports and xrefs I don't want in the file.

Then I run a LISP called purgeoff. It's been so long since I found it, I don't know what all it does. I'm sure Superpurge does some of the same stuff, but I believe purgeoff will try to delete layers and all their objects if you have the layer hidden, but maybe not.

After that I run another LISP to delete all layer filters.

When I run these three items, I can drag just about ANY file to less than a meg. Unless of course it just has huge amounts of data.

Yes Stykface, LT is the problem, I'd much rather have the full version, even if it is overkill. Cause LT is underkill. If your carpet cleaner leaves dirty spots all over the place, dirty corners and streaks, it's not just nitpicking to want him to clean better. And it's not nitpicking to want the same thing with aCAD. If they leave so much junk data in the file that isn't needed and I have to rely on 3rd party programs just to keep files clean and small, I have a right to demand higher performance from this expensive software that needs help from freeware utilities to run properly.

I am just totally unimpressed by LT 2009, it's a $40 program at best. There new menu system is annoying, and I can't get the dang layouts to show up as tabs at the bottom, I have to use their stupid floating bar, which, by the way, if you have a lot of viewports, you can't even get back to the model view because it doesn't let you scroll left, only right.

One thing I'm happy with is that they simplified the plot dialog box which became overly complex in the 2006 version. But now it's too simple, they don't let you choose the pen style from the dialog, you have to choose it within the document, or else set a default style through the options dialog. This isn't a bad thing for me, since I always want to use the same style.

In any case, if I can get viewports to appear as tabs that would be nice. I know they say you can right click down there and just select the option, but that option doesn't exist on mine.

AutoCAD to Carpets.... whu???

Well this client of mine does not even let me use normal purge on the files. he has given me template & specifically as me not to purge

Does any one have any idea fo reducing the file size without using purge?

I found the cause of the problem, so thought I will post it. For one of the project, I had change the default save as type to 2000 version in my laptop& didn't rememebr.

When I worked on this file on another machine after saving it went to 5mb from 32 mb. So while checking some of the options I saw that it had default save as 2007. I also tried it with save as 2004 & it was still small size. but if you try to save it back to earlier than 2004 it is going up in size
