1. “iTunesDSM can find duplicate files but when I click the Clean iTunes button nothing happens.”
This can happen if you try to run iTunesDSM from within the zipped folder (.zip) you downloaded. Extract the zip folder and try running iTunesDSM again.
2. “Sometimes when I click the Add Tracks to iTunes button, nothing happens.”
This appears to be an issue with iTunes and possibly something called JACOB. Unfortunately, this issue is intermittent, and the only way to fix it is to close iTunesDSM and run it again.
3. "iTunesDSM is not finding any duplicated files, but I know they are there."
iTunesDSM relies on iTunes keeping your music files organized. The setting is in Edit > Preferences > Keep iTunes Media Folder organized. If this option is not enabled then iTunesDSM will not find any duplicate files.
4. "Can I search for duplicate files in other directories?"
Yes, just change the music directory for each search you want to perform and then rerun the Find Duplicates and/or Add New Tracks searches.
5. "What are exclusions?"
iTunesDSM has to keep a list of files that have already been added to iTunes from outside of the iTunes directory because adding tracks to iTunes programmatically can produce duplicated files. In other words, you can add files inside iTunes' music directory without incident, but adding songs outside of the directory can cause duplicate files to occur. It's all maintained automatically so you shouldn't need to worry about it.
6. “What happened to Mac support?”
iTunesDSM is written in Java so yes it does work on Mac, but iTunesDSM relies on COM’s to read information from the iTunes libraries. COM’s are not available on Mac so a lot of the iTunesDSM functionality is lost. I have looked into Apple Scripts, but since I don’t have a Mac, I can’t test them.
Be sure your Mac is set to use JRE 1.6 to run iTunesDSM. You can find this option in Java Preferences, search for it in your applications.
7. “What are orphaned files or orphaned tracks?”
Orphaned tracks are those tracks in your iTunes library that have the exclamation mark next to them. The exclamation mark means that the file that iTunes used to use to play that song no longer exists. iTunesDSM can automatically remove these orphaned tracks in the Remove Duplicates tab, while keeping the rest of your library intact.
