Game Backup Creates inaccessible Folder

[aCanuck]

Some recent changes to the backup/restore system have made it impossible to backup certain games. The current system does not give an option to name the backup so it will automatically be the same name as the game, which is a PROBLEM with some games. For example, I just backed up a game with a period at the end of the title, and now Windows (10) won't let me access the folder it created because the "Location does not exist" and when I try to rename it by removing the period Windows tells me I'm trying to change the file extension, and then still says the location cannot be found.

Edit: To be clear, I don't need advice on how to remove the folder, mostly just pointing out a problem with Steam backup. I used Windows CMD in admin mode to force the folder to be deleted

rmdir "\\?\C:\Folder\Name." /s

update and change info.
Ask steam support, make ticket , because either security prevent make root folder, ( well known old rule with app dont should have access to ROOT folder.

But i had no issue make new folder at root, so maybe you have own NTFS issue with Folder user rights

Do note C-drev has more security sense its boot disk and OS for many ppl. ( even that matter and some folder even more. ( Document and Program files , hidden folder and so on, windows in itself so many NO NO's, or should said avoid them to reduce user mistakes. )

Other third part security app can raise security even further, try other location.


gl with it.

I mean steam backup and restore a game, is a simplified function, not even sure a user can make mistake here, this is why you should make ticket, it should just work with no issue at all.


And the more ticket they got about it, then they will test for such in the future, if they dont already do this.

ps.
Dont forget many of us dont even use that function, thats why make ticket is a nessary then you use that steam function.

Other intel on subject, dont forget we other have use tape or other backup media and apps, and comparer to steam backup solution then we can be seen master on the subject, there is no option in that backup procedur. any old windows users know this from the past. i think.

This has nothing to do with any type of access permissions on files or folders.

The problem is the trailing period. The 'normal' Win32 file path handling APIs don't support certain characters in certain positions. But the actual NTFS filesystem has no problem with them. And if files or folders are created via other means than those old Win32 APIs, you can end up in a situation where files or folders exist in perfectly fine order in the file system but are inaccessible to many applications - including system applications such as Explorer, which still go through the old Win32 path handling.

The escape hatch is what OP already used:
Device paths that start with the leading \\? or \\.\ segment.

These work, because those paths are not sanitized, i.e. are not checked for 'illegal' characters, by the Win32 API before access.

Ahh yeah. Good point RIO, but also a problem then OP is in trouble with selfmade name, i also read it as a RMdir cmd only, detail matter here we can all agree on that and yet still a steam support problem if default game name has such, its part of the issue.

Also seems to be missing stripe illegal characters in name then created, so many issue with this

This is not a new problem. I attempted to report this in 2015 and it remains unfixed.
It's just worse because you can't rename the backup folder manually anymore.
