I suggest looking for one of the sub-folders ... which has a simple spelling.... such as 2009. Once you find that you can check its parents to get to the top of the tree. Search in all drives, including the 'recycle bin'.
If still struggling ... I would consider the tool called 'Everything'. I have no association with the author.
One of the best tools I have come across for searching for files or folders is called Everything. It puts the standard Microsoft search tools to shame. Seriously.
You can find it here. https://www.voidtools.com
Not sure if it is free, has a trial, etc... but worth checking out.
1. It took me a few mins to figure out how to use it. There is a drop down selection option, not easily visible on the top right hand side. You can select 'folder as the type of object to find. Box 1 enter the folder name (eg 2009) or part thereof. 2...Select 'folder' as the object to search.
2. You have to configure it to include extra drives.
Use these instructions to select the F drive or any other drive.
I only had to do this config once. It remembered the setting for subsequent sessions..
How do I add a folder to the Everything index?
In Everything, from the Tools menu, click Options.
Click the Folders tab.
Select a folder to add to the Everything index.
I have bought loads of utilities over the years to search for files and folders. This is the best tool I have come across. Further, you can configure filters which can be added to the drop down list. I have added specific filters for Word (all types), Excel (all types), PDF, etc I have also added a specific filter for Word Templates as they can be often difficult to find and I may wish to eliminate looking for generic Word docs.
It took me approx. 15 mins to set this up to suit my needs and I have never had to revisit config or options settings since.
