System Out of Memory error

Question

I regularly have Studio projects containing around 2500 files. Some operations on such projects take > 5 hours (for instance opening an analysis report) or are impossible (for instance opening all files in the Editor, filtering a subset, locking the subset and saving the files again) because Studio hangs or crashes with a System.OutOfMemory error message. It is not the word volume that causes the trouble, but it is the number of files. The problem can be reproduced at any time. 
 Conditions: Windows 10 Studio 2017 (with latest updates) Studio 2019 (with latest updates) intel I7 8th gen, 16 GB RAM, 512 SSD HDD (also tried on lesser equipped machinery) 
 Steps tried but no result: Unlinked all TM's from project Project resurrected RAM usage monitored: never exceeded 3 GB (This is a 32 bit app!). Removed all SDL temp files from \appdata\local	emp (there are lot left behind after a crash) Clean start, no programs open but Studio

Hello Marcel Brugmans , 
 
Please take a look at the following articles on System Out Of Memory issues.

Well, that article is... useless. Because there is enough RAM in the machine and there is NOTHING what can be done on the user's side. 
 The main problems are: 
 
 Studio working with the files in very inefficient way 
 Studio still being only 32-bit application 
 
 I hope you do realize that Studio won't use more than ~3.5 GB RAM, no matter how much RAM one has in the computer. 
 Marcel Brugmans : You can try to restart the computer before using Studio, in order to minimize the memory fragmentation problem ( https://stackoverflow.com/questions/3770457/what-is-memory-fragmentation) . However, with such a big amount of files it's not guaranteed to help, unfortunately.

Hi 
 
Thank you for taking time to test this... it is certainly useful background information and you make some good points about loading the embedded content. I've shared this with the developer for comment and perhaps we can look at this in more detail after Xmas in the New Year.
