I keep my files on a NAS and access the encrypted files over a network share.
I noticed the following:
Without "nonFixed" the access to my files is very slow (reading directories and transfer in general - reading a directory with ~ 2000 files takes minutes!) but I can access every file without problems.
With "nonFixed" reading directories is much faster but not all applications can access the files without problems. For example I could copy a file with total commander but couldn't start the file with the connected application. So I had to copy the file to my regular drive before I could use it.
Boxcryptor 184.108.40.206 didn't had these problems. Reading directories from NAS was faster and accessing the files wasn't a problem.
I'm running version 220.127.116.11 on Win7-64bit
