| + | Encryption of file names uses Base64 encoding. To preserve file names encoded in Base64 encoding, the target file system should be case-sensitive (Linux servers use case-sensitive file systems) or at least case-preserving (with a small risk of collision -- Windows NTFS is case-preserving). | ||
