Remote syncs use the Files.com case sensitivity rules.

An effect of this is that multiple source folders which have matching names, but using different cases, may be omitted from a sync run. This is to avoid data being irreversibly merged into a single destination folder.

For example, if the source of the sync contains folders named MYSTUFF and mystuff, and the destination contains a folder named MyStuff, then the sync will omit those source folders from the sync run. This avoids data from both the MYSTUFF and mystuff folders being irreversibly merged together into the destination MyStuff folder.

The same applies when there are multiple matching destination folders, which means that the sync cannot determine which of the destination folders is the correct target.

When these issues occur, the following messages will appear in the logs:

Skipped due to multiple files/folders having the same case-insensitive name on the source.

Skipped due to multiple files/folders having the same case-insensitive name on the destination.

To resolve this, ensure that the sync source and destination locations only contains a single copy of any folder name, regardless of case.
