error 101, moving files to folder by artist

i am organizing my music files to folders by artist. the file names are already set to <artist> - <track>.midi e.g. Michael Jackson - Thriller.midi.

I set the batch mode to copy with the output folder: C:\downloads\music\<substr:1:->.

however, i am getting error code 101. when i check in explorer, the program is creating the folder but not copying the file. there is no restriction on access on these files.

i dont know what is causing the error.

please help. thank you in advance.

nevermind i fixed it. the error is in the <substr> tag on the output folder. it includes in the return the space which causes the error. tag should be <substr:1: ->.

anyways hope this will help others.
