    Let me present some figures, as reported by iPad, iOS 5.0.1:
    Total size of DT, including documents and data: 7.8 Mb
    Size of documents and data: 1.8 Mb
    Size of documents as saved to iCloud: 614 Kb

    While DT is at work I can understand it accumulates a massive heap of data and metadata.
    When, however, the app is quitted, you might suppose it flushes redundant data. Instead, it keeps them, adding to an ever growing and alarming total size. To flush I have to reset the iPad, sometimes even to reinstall DT.
    To keep the numbers of stacks and sheets low seems sensible procedure.

    Repairs under the hood are called for?

    In addition to the above I forgot to mention that after resetting the iPad, total DT usage is reduced to 7.4 Mb.
    As I just noticed the same behavior with other text apps, I presume the fault is with iOS?

    Hello khop!

    Thank you for using Daedalus!

    First of, 7.4 MB is not much. About the size of two photos these days. Your iPad has 16000 MB space at least, with almost all apps taking more space. To be honest, I don't see a problem here and no need to optimize.

    Even if I wanted to optimize, most of the space is taken by the app itself. As reading from your figures, this seem to be 6MB, or about 3/4 of the taken space. And then, most of the remaining space is occupied by the system itself. We have embedded web browser, which might be caching data and so on.

    I don't think that storing any number of stacks and sheets will significantly increase the taken amount of space. This is just text and that doesn't take much space.

    As I said, we don't actually see any need for optimization here. Max

    Hi Max!

    Let me explain once more. I'll do it step by step. Bear with me…

    Reinstall DT
    After installed, usage : 6,1 Mb
    After first opened, usage: 6,7 Mb
    After delete Help files, usage: 6,9 Mb
    After hard reset iPad, usage: 6,2 Mb
    After open DT: usage: 6,9 Mb
    After creating one stack, one sheet, three words + title, usage: 6,8 Mb
    After removing DT from multitasking bar, usage 6,4 Mb
    After restart iPad, usage 6,3 Mb (one stack, one sheet, three words + title)

    Maybe the multitasking functionality is to blame, as other text apps show the same behavior. Which would make it an iOS issue?
    I recall the Newton days. There existed a little app, called Garbage Collect. However, it would free mem, not redundant metadata. 

    Daedalus forever!

    Best, 
    Peter

    There are very many things going on in the system a developer has no control of. The multitasking e.g. may write some of an applications state to disk etc. These common system-defined behaviors definitely explain why many pas show similar behavior.

    Again: 1 Mb difference is nothing to worry for me. And I think you will still be able to see similar figures when pasting three novels into the app.

    Yeah, Daedalus forever! ;)
