today i found a strange behavour which confirms the problem with portable version, i think it is not due with truecrypt if you mount true crypt volume in normal mode (not as removable device) so all will works. only one difference: btsync using full path to folder not relative like this "..\..\..\sync folder" also it does not correct recognize folders with dot in name, for example if folder "..\..\btsync.folder\something" the paste "..\..\.folder\something" i repeat, these problems started with version 1.0.135
