I have a folder inside Dropbox that I'm trying to use for some hobby C++ development using MS Visual Studio
I followed the process to have Dropbox ignore the temporary build folders (like /x64 and /.vs)
In Dropbox I can see that this did indeed stop Dropbox from syncing any of the files in those ignored folders
However, using Process Monitor, I can still observe that Dropbox opens files inside those folders and queries various bits of information about them
I do notice that it opens these files with permissive 'share modes' that allow other processes to 'read / write / delete', however this still causes problems with Visual Studio's build tools, because THOSE tools do not open some of these build files with permissive share modes - they specify NO sharing, which causes them to be unable to open those files, and builds sporadically fail.
I would love to use Dropbox as a simple shared folder like this, however it doesn't seem workable in this situation without dropbox promising to not open files that it knows are in ignored folders.
