What makes .mdb files so big?

    Just noticed that .mdb files are quite big for the amount of data they
    contain.
    A .mdb file is about 50 times bigger than the corresponding text file
    holding the same data.
    What makes up the size?

    Mostly junk disk space, use Tools | Database Utilities | Compact and repair
    database if you have been deleting tables or lots of records. It's a good
    idea to do it periodically anyway.

    Have you compacted lately? It will always be bigger that a text file, but they
    files do "bloat" during use and compacting them will get rid of that.

    This is a completely newly created file.
    Created via VBA.
    It is not really a problem (yet), but just wondered.

    There is always a significant amount of overhead for the first record.
    One of my client databases, when all the records in all 160 tables
    have been deleted and compacted, shrinks down to about 3 or 4 Mb.

Since you're here... we have a small favor to ask...

More people are visiting & reading SPN than ever but far fewer are paying to sustain it. Advertising revenues across the online media have fallen fast. So you can see why we need to ask for your help. Donating to SPN's is vote for free speech, for diversity of opinions, for the right of the people to stand up to religious bigotry. Without any affiliation to any organization, this constant struggle takes a lot of hard work to sustain as we entirely depend on the contributions of our esteemed writers/readers. We do it because we believe our perspective matters – because it might well be your perspective, too... Fund our efforts and together we can keep the world informed about the real Sikh Sikhi Sikhism. If everyone who writes or reads our content, who likes it, helps us to pay for it, our future would be much more secure. Every Contribution Matters, Contribute Generously!
