Since upgrading ArcGIS Pro from 2.1 to 2.2 a couple days ago I have not been able to save a project. Is anybody else experiencing this?
A few more details would help, how are you creating the project, are you "Saving As", was this a project created in 2.1? Folks on GN might be able to help, but your quickest path might be tech support. FWIW, I'm not able to get that error.
...and I've ruled out your use of "_" and "-" together in the path, which was my first suspicion, as I can save a project in C:\temp\FOLDER_NAME_TEST\Supercali_fragilisticexpialidocious\Supercalifragilistic-expialidocious
The project was built from scratch using Pro 2.2. I used layer files created with ArcMap 10.3 to symbolize a couple of the layers. File name does not contain spaces or special characters. When attempting to save onto C drive was at top without using a folder/directory. Layers are all feature classes. Couple layers use simple definition queries.
Laptop uses Windows 7, 8 gig of ram with enough available space on C drive.
IfmMemory serves.. you can't save to the root folder…. but it is? coming
