I'm working with a windows, 64 bit, using .91 for 32 bit (the 64 one caused my computer to crash).

So this new problem occurs with large files (113 mb). I know this is very big...
Anyway, the file starts to run slowly and I hit save.
Instead of saving the file, the save as box appears, prompting me to create a new file name. I do so and then at the bottom a message reads "file not saved."
At that point, I can't save and there is nothing I can do. When I go to exit I receive the warning "do you want to save?" When I try to do so I cannot and have no option but to shut down without saving.

Thoughts?
thanks

How much memory (RAM) do you think that Inkscape have to use for that big file? Try to open program manager and see how much ram is used by Inkscape when that big file is loaded.

I think that it is just too much data for a 32 bit aplication to handle.

Here is a picture of the program manager, taken right while I was in the midst on working on that file.
From what I can tell, it's not a memory issue?

so.... what computer specs would be needed to handle that size of file without lags, crashes or friezes...?

ie: how much RAM, processors...
thanks

It seems like we've covered these issues in other topics. But we'll try again. With Inkscape, the primary factor is RAM. The CPU only comes into play with filters, and perhaps other raster content (I'm not sure about the "other raster content"). Are there a lot of filters in the file, or any?

For using the Task Manager to get an idea about RAM usage, you'll need to have it and Inkscape so that they are open side by side (not maximized) and both visible. Do something like Select All, and try to move the selection. Undoubtedly there will be some lag time, while Inkscape tries to comply. So immediately after you release the mouse, and while Inkscape is working, that's when you need to look at the Task Manager for the RAM usage. Keep watching to see what happens. Or maybe even better, watch the Task Manager while you try to save! I guess I don't really know this for sure, but I've always thought the Physical Memory is the RAM usage.

Even if you had 16 gb of RAM (the most I've ever heard of), I guess that would take at least 50% of your ram, in that 113 mb file. And I wouldn't be surprised if it took 100%. I just don't have any experience with a computer having that much ram.

One thing that's missing from the Inkscape community, and specifically Inkscape, is a set of system requirements. I'm not sure why. But all we have is anecdotal evidence. For me, with only 4 gb RAM, the performance issues I see in only a 5 mb file will usually prevent me from working on it. If I only tried to open your 113 mb file, Inkscape would crash. I have been able to open 20 to 25 mb files with Inkscape, but I can't do much to them, without Inkscape crashing.

Hi Brynn
Sorry I didn't get back to you...I appreciated your comments and thoughts.
You're right - some of my questions were related to other topics. I suppose with each new file I (often) encounter new problems and believe (hope) there may be a readily available fix addressing a unique and isolated underlying problem. However, that doesn't seem to be the case. Also, I still do not entirely understand my computer's various components (memory, ram, etc.) so my questions also reflect that confusion.

Your comment regarding a set of requirements makes a lot of sense - having them would be useful.

Again,thanks for your suggestions. As always, your input (referring to this and your other suggestions responding to my earlier questions) is informative and helpful.
