### Describe the Bug

I want to have Floccus save the "bookmarks.xbel" file to a specific directory on my Google Drive instead of the default root directory of my Google drive. I've tried various methods to make this possible, but Floccus refuses to place the "bookmarks.xbel" anywhere on my Google drive except the default. I've tried "\" and "/" in the floccus bookmark file locate such as "\Folder\bookmarks.xbel," "/Folder/bookmarks.xbel," "Folder\bookmarks.xbel," and "Folder/bookmarks.xbel." All these error out in floccus during sync. I have also tried the following "Folder>bookmarks.xbel," but floccus just names the file "Folder>bookmarks.xbel" and drops it in the the default Googel drive directory anyway. I have tried all this methods with a pre-existing directory name "Folder" and also tried to get floccus to create the non-existent director on Google drive - none of these work .

### Expected Behavior

The user should be able to tell floccus to place the bookmarks.xbel in a specifcc Google drive folder that is designated by the user.

### To Reproduce

Try to configure any of the following Google drive file folder/file name directives in the "bookmark file" configuration section of floccus:

"\Folder\bookmarks.xbel,"
"/Folder/bookmarks.xbel,"
"Folder\bookmarks.xbel,"
"Folder/bookmarks.xbel."
"Folder>bookmarks.xbel,"
