-	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).	+	Encryption of file names uses Base64 encoding.

	The file system also needs to support reasonably long file names. Base64 encoding adds a 33% overhead to a filename length. Additionally, an encoded salt and the ''.aesctr.enc'' extension add another approximately 33 characters.		The file system also needs to support reasonably long file names.
