OneDrive

I get an error where trying to sync folder or file which name ends in a dot?

Unfortunately OneDrive does not support folders or files ending with a dot, so trying to sync a folder named "MyFolder." or "MyFile.jpg." will fail with an error.

To solve this you need to either: rename the folder or file to not end with a dot, exclude it using a filter or use another cloud provider.

I get an error downloading HEIC files

This appears to be a long-standing bug in the OneDrive API that only allows for downloading the image part of of heic live photo: https://github.com/OneDrive/onedrive-api-docs/issues/1723

The issue is the OneDrive API reports the full file size for both image/video but only the image part is downloaded with the file. There doesn't seem to be any workaround that would allow Foldersync to download a file identical to the originally uploaded file.

To eliminate this error you can exclude the file or file type using filters.
