I was not familiar with that page, thank you for providing it. I did take a look into the .bat file and it seems to delete the AppData../FileHistory directory. If I understand correctly, this doesn't attend to the matter of FileHistory insisting on backing
up a dozen predetermined directories upon its first run. For reference, these are the required exclusions that are ultimately needed to have a "clean" File History installation:
<FolderExclude Hidden="true">C:\Users\user\Saved Games</FolderExclude>
<FolderExclude Hidden="true">C:\Users\user\Links</FolderExclude>
<FolderExclude Hidden="true">C:\Users\user\Downloads</FolderExclude>
<FolderExclude Hidden="true">C:\Users\user\Desktop</FolderExclude>
<FolderExclude Hidden="true">C:\Users\user\Favorites</FolderExclude>
<FolderExclude Hidden="true">C:\Users\user\Contacts</FolderExclude>
<FolderExclude Hidden="true">C:\Users\user\3D Objects</FolderExclude>
<FolderExclude Hidden="true">C:\Users\user\Searches</FolderExclude>
<FolderExclude Hidden="true">C:\Users\user\OneDrive</FolderExclude>
<FolderExclude Hidden="true">C:\Users\user\Documents</FolderExclude>
<FolderExclude Hidden="true">C:\Users\user\Videos</FolderExclude>
<FolderExclude Hidden="true">C:\Users\user\Music</FolderExclude>
In order to get to this state, however, one is required to start and then immediately stop File History, which makes me suspect there is something there in 2004 that gets cranky when doing so.
As for your questions, I can confirm that using the "Clean up" feature prior to 2004 worked like a charm. I have used it at least 3 times in the past year with what must be versions 1903 and 1909. So, it was a surprise to see this "Element not found"
error upon trying it for the first time in 2004. It was an even further surprise to see it persist upon clearing and retrying from a clean copy/version of FileHistory, which led me to my posts out on the interwebs.
As a final thought here, upon re-reading your provided link, it's interesting to note that File History makes use of a NTFS feature called change journal. You have to wonder (and hope) if this might be related to the
Storage Spaces bug found in 2004 which also deals with the file system. Hopefully fixing that will address this, too. But, who knows. 🤷♂️
