"This file is currently not available for use on this computer"

I am hoping someone has had this issue before and can help me resolve. I was working on a company project. I had just finished up and needed to publish my project to the server. When trying to publish, I got the error "This file is currently not available for use on this computer."

So then I tried to open one of the .cs files of the solution, and the error occurred again from trying to open the file. So I tried to grab the latest version from TFS thinking it would give me whichever file is missing, but when I click "Get Latest Version" on the project, the error message pops up there too.

I thought surely I will be able to delete the project locally and then remap it, but I can't even delete the project off my computer, as the error message pops up halfway through deletion. When it occurs there, however, I do get "Error 0x800710FE: This file is currently not available for use on this computer."

Also have tried deleting offline cached files through Control Panel > Sync Center > Manage Offline Files > Disk Usage > Delete temp files

I got this error for a small, test solution that was not using TFS. The default file location is the documents folder, which in my environment is synced using the Sync Center. I moved all of the solution files to a new local folder that was not included in Sync operations and the error went away.

Conclusion: storing VS files in a folder managed by Sync Center is likely a bad idea.
