…and Google doesn’t seem to care! There are posts from years ago on the Google forums, and responses from Google admin saying “we’re looking into this,” but the problem still exists (in Win 7 and Win 8).
I have tried uninstalling/reinstalling Google Drive, but to no avail. And it’s a serious pain in the butt, because every time you do this, in order to associate a folder with Google Drive, the drive has to be empty (you can’t associate a folder with any contents). So once you’ve reinstalled Google Drive, you have to create a new folder, associate it with Google Drive, dump all the contents of your old Google Drive into the new folder, rename the folder, and then wait for Google Drive to figure out what the hell just happened (update sync database).
In a thread discussing problems with Piriform’s CCLeaner and Google Drive, I found this information:
When the Google Drive application is running, it creates a directory under C:\Users\Chukhung\AppData\Local\Temp with a name like "_MEI54082" (the last five digits of the directory name change every time the Google Drive application is started). Within this directory are a large number of subdirectories, DLLs, and what appear to be Python files. This directory disappears when the Google Drive application is shut down manually. [. . .] I'm guessing that Google Drive gets seriously confused when CCleaner partially deletes the contents of this directory.
This seems like a pretty decent guess as to why this is happening, but I’m not sure what to do about it (other than to always manually shut down Google Drive before shutting down the computer, which isn’t exactly an ideal solution).
I will update this post if I find a solution, but in the meantime, feel free to post your thoughts/solutions in the comments!
