Hi everyone,
I'm trying to reduce the file size of a DGN file that contains the city of Toronto. I need to create smaller separate files in order to import them in another software. I was able to delete elements and keep only a small fraction of the model but the filesize stills the same...
Could you help me?
Thank you!

Not really as Gerad made the following statement and I was responding to it not the original post.
quote "...... it is probably one of the huge perpetual sources of income for the digital storage hardware industry "
Plus I enjoyed showing the contrast between the technology costs from less than 25 years ago... most youngens have no idea of what it was like for us users in late 80's
We needed to compress whole network ( clix/ unix) directories daily to stop IT departments moving folders around to make more room .. in my instance messing up reference paths....

What Phil says is correct in that once you delete elements in a design file they are not marked as deleted but are immediately removed which should reduce the file size straight away.
Compressing the file will get rid of any unnecessary details within a file but only if this information is no longer required.
I think the better option would be to reduce the file size by extracting only the required detail out to a separate file using the FENCE FILE command.
FENCE FILE (FF=)
Used to copy the contents of a fence to a new DGN file.

but it has gotten cheaper and cheaper..
My flash or thumb drive 16Gb cost me $15 ( 2014) my first hard drive ( amiga Scusi late 1980's) 300Mb cost me $300 we used to get $15 /hr pay in late 1980's
Today internal 3 Tb hdrive cost <$150 yes servers space is a little more but per Mb its tiny ( 0.005cents /Mb= 15000c/3000x1000 Mb)
just using the thumb drive 16gb is approx 1/2 hour pay so 16000Mb for 1/2 ( or 32,000 Mb /1 hours pay, ) old drive 300Mb for 20 hours pay = 15Mb for 1 hr pay
so 32000/15 = 2133 times cheaper mb for mb today or another way if you could buy todays 16Gb drive back in the 80s with 80's 'money $1/Mb would have been $16000 ( but in todays money would still be $4000... yet today it costs only $15 or 9 cents / Mb in todays money for thumb drive)
or if 3 Tb intern HD equivalent was in 1980s tech and money even then at $1/Mb would be $3 million or $12 million in todays money not $150 (0.005cents/Mb) which also shows thumb drives are very expensive per mb compared with HDs
so today storage space is so cheap today who cares about space... so much that a lot of my friends now have refurbished their old slow laptops instead of getting new faster ones have opted to put small solid state hds for windows and programs to load on and get very big improved performance... I'm thinking of doing the same on my desktop...
