Are you sure you are in 17.0.50? It looks like the design has changed in the Rename,Move box. There is now both a base path and rule box for the Directories entry, which means now you can't set the starting point to different hard drives.
Here is an example that may better illustrate the problem in 17.0.50
Rename, Move, & Copy Files box
Directories
--------------
Base Path - I left this blank, I want my Directories Rule to set the starting point for different hard drives.
Rule - see below
IF(ISEQUAL([Media Sub Type],Audiobook,1),IF(ISEQUAL([bsSeries],unknown,8),[bsAuthor]\[Album] /([bsNarrator]/),[bsAuthor]\[bsSeries] /(series/)\[bsSeries Num] - [Album] /([bsNarrator]/)),FORMATRANGE(CLEAN([Album Artist (auto)],2),2,0)\CLEAN([Album Artist (auto)],2)\[Release Type]\FORMATDATE([DATE,0],yyyy-MM) [Album]\[Rev Year]-[Rev Name]\IF(ISEQUAL(LEFT([Rev Format],4),Quad,1),[Rev Format]__[Rev Format Details]__[Source Format],[Rev Format Details]__[Source Format])\[Source Media])
Filename
--------------
Rule - see below
IF(ISEQUAL([Media Sub Type],Audiobook,1),IF(ISEQUAL([bsSeries],unknown,8),[bsAuthor]\[Album] /([bsNarrator]/),[bsAuthor]\[bsSeries] /(series/)\[bsSeries Num] - [Album] /([bsNarrator]/)),FORMATRANGE(CLEAN([Album Artist (auto)],2),2,0)\CLEAN([Album Artist (auto)],2)\[Release Type]\FORMATDATE([DATE,0],yyyy-MM) [Album]\[Rev Year]-[Rev Name]\IF(ISEQUAL(LEFT([Rev Format],4),Quad,1),[Rev Format]__[Rev Format Details]__[Source Format],[Rev Format Details]__[Source Format])\[Source Media])
RESULT
----------------
My previous version (17.0.42 or 17.0.3x):
H:\Audio\Music_Surround\C-D\Carly Simon\Regular\1971-02 Carly Simon\Quad Q8_PCM 4ch\2008-Quad Q8 [Romanotrax 2008-07]\disc 1\02 - Alone.flac
17.0.50:
Dialog box pops up - "The base path is undefined. The path the files currently resie in will be used as the base path"
If I answer no, then the dialog box is dismissed and I have to set the Base Path.
If I answer yes, then the file's current location is used as the base path, resulting in...
H:\Audio\Music_Surround\C-D\Carly Simon\Regular\1971-02 Carly Simon\Quad Q8_PCM 4ch\2008-Quad Q8 [Romanotrax 2008-07]\disc 1\H_\Audio\Music_Surround\C-D\Carly Simon\Regular\1971-02 Carly Simon\2008-Romanotrax\Quad Q8__DVD-Audio__PCM 4ch\disc 1.flac
Note that there is no longer a filename entry in the move/rename box, so now it looks like my rule also needs to be changed. I did not yet change this in my rule so that is why my file was renamed with no name.
Does this help show the problem better? Thx
