Free up Memory to Reduce Size of .DWG File

[Anonymous]

I have a drawing that was once huge, but has had most all of the content deleted.  The .dwg file is still the same size even though I purged and audited the file.   How can I get rid of the useless data the file is carrying?

Are the ringed items in the image below ticked?

You missed to share your file  or how could we KNOW the content and how to get rid of <whatever>.

First thing you can try is, use PURGE to delete unused definitions.

Another way is, use WBLOCK (but you won't learn what was the "big" content).

Wblock, Option 'Object selection'.

By this way you creats a new file  without your layout.

If it works, use DC/CTRL+/adcenter

to import your layouts,

check filesize again.

Sorry, new to this.  Didn't see that I could attach the file.  It is attached here.

I am going to try again as I am not sure I followed your directions properly.  Size of file has not reduced yet.

Yep making sure the purge orphaned data box is tick will work. You have tons of redundant microstation linetypes in that drawing. Running a purge got the file size down to 151kb

Using the option to remove orphaned data shown by @h_s_walker above worked for me on your drawing, it reduced the file from 13.5MB to 0.5MB.

But also using WBLOCK reduced it then down to 0.1MB you have an awful lot of linetypes 'stuck' in your drawing file

It seems that my PURGE isn't purging.  I PURGEd before I attached the drawing and it didn't shrink.  But glad to hear that that is indeed, in the long run, the answer.

Thanks for the help.

My PURGE pop up window does not have two lines under UNNAMED OBJECTS.  Just the one "Purge zero-length geometry and empty text objects".

Hi,

another thing you forgot to say

is your software product name and version.

Start command ABOUT and share a screenshot.

For OLDer versions of LT you can use the WBLOCK way to get rid of these microstation linetype, as you can read above.

Try first option Entire Drawing, if it doesn't help(i can not test it, i am without Acad now)

use the 'object selection' methid of wblock command.

Just using the WBLOCK command mentioned first by @cadffm will also reduce the file size down to 0.1MB
