Hello,
After working for a few days in a project and ‘‘saving as’’ to prevent any problems, an error started appearing while saving.
Warning
Save project
PermissionError
Saving user-data - folder for may be read-only
Neither of the past versions and the latest one are saving properly anymore. Is there any way that this can be solved, or should I start from scratch again? How can I avoid it in the future?
Thank you very much in advance,
Alejandra
Hi Alejandra,
we had someone with a similar issue a few months ago. Are you working on Windows? And if so, is your Windows installation definitely up to date? There was a Windows error some months ago which could have caused issues with saving.
Are you saving your project locally or on a network drive? We don’t recommend saving on a network drive as even small outages in the connection can cause unexpected data loss which may compromise the project.
Looking back at the emails from our previous user with this issue, I don’t think we ever conclusively worked out what the issue was. But it seems to have been linked in some way to having project names that were too long. If you send us your project to support@ccpn.ac.uk we can take a closer look if you like.

Hi Alejandra,
As Vicky has already indicated it would be useful to know what OS are you working on and where your project is saved.
Users most often encounter this type of problems on Windows when working with a cloud drive such as OneDrive. The authentication methods used in these systems don’t keep their knowledge of a user’s permissions up to date robustly so you can appear to lose write access to a location. Unfortunately this is something that even Microsoft don’t seem to be able to make to work reliably for their own software!
To work around the issue, we therefore recommend always keeping your project’s working copy (the .ccpn folder/directory) on a local drive if you are on Windows. Use the archive mechanism to keep timestamped backups that you can upload to your cloud drive in case of local data loss. Your raw data (spectra) don’t need to be stored locally since they are typically only read.
Best wishes,
Brian
Yes, im working on windows but I dont see any new update. I dont know if its relevant, but we have windows 10 and our IT department do the updates.
Im saving them both locally and the network drive. But when I tried to put it on a folder that saves only locally it gave the same problem, I will take that into account for future projects.
Im going to send you the project to the email just in case.
Thank you for your help,
Alejandra
I tried moving the project to a local drive and shortened the name of the project and now it seems to be working properly. Lets hope it continues behaving!
Thank you very much for your kind help!
Alejandra
Great that things seem to be behaving again. I’ll still have a check to see what there is we can do from our side to stop this kind of thing happening.
