Lost and Found .c9r Files at Drive File Stream

To solve the topic I’ve lay here my solution for all this trouble.

After uploading everything to Google Drive using Drive File Stream, I went to lost and found folder, wich in windows is:

C:\Users\XXXXXXX\AppData\Local\Google\DriveFS\XXXXXXXX\lost_and_found

And copied the name of the files that was in this folder, to search on the “d” folder of the vault.

This way, the search bring me the exact location of each file, wich I had to mannualy reupload to vault in Google Drive. (using the location that the search on folder “d” at local vault returned).

It was just fine and take me only 30 minutes to do. The next part was a liitle bit more confusing and hard to solve.

One of the files in lost_and_found folder was a “dir.c9r” wich is widely repeated on a vault structure.

To solve out from where this file was taken, I had to open op the cloud vault on pc in WebDav mode, and use the app WinDirStat to find out that was one folder pointing to root of the vault. This folder was supposed to have 13 files inside, but when I get to this folder at vault, it used to bring me to the root vault folder.

I tried to rename or delete this folder, and renaming don’t resolve nothing, deleting will delete the whole vault. So, I solved like this:

Renamed the folder on cloud vault (mounting vault on cryptomator application while the files are located in File Stream drive), and checked on the Drive File Stream application to know wich file was renamed.
When sorted out, I just opent the folder that was renamed, and inside was a “dir.c9r” file without any data inside. I just copyed the data from the one tat was in lost_and_found, relaunched vault and voi-là, the structure was now perfect, the 13 files was showing correctly and everything was fixed.

Now I dont know what to do about uploading more 3tb for vaults in Google Drive. Since as I can see there is no application that could do this without lots of errors and failures.

Anyway, I let it here for someone that could face the same problem in future to solve it out by themselve.

Thanks @infeo and greetings from Brasil.
