The search function on this is total garbage. Don’t buy this app if you need one.

Good but still needs some improvement

I have close to a dozen external disks so this tool comes in very handy to manage them. I didn't turn on the thumb image and duplicate file function so it scans pretty fast through most of my discs. However, it completely choked on one of my My Book 1TB hard drive, progressing only a few GB after 30 min. Same results after I tried 3 times througout a week. However, my computer was reading and writing from that disc perfectly fine. Here are some improvements I would suggest:

1) For each disk scanned, it would be nice to add the total volume information besides the current file size on that disc.
2) Add a progress bar or some information while scanning as it still takes a few minutes to go through each disc so this would be helpful.
3) There doesn't seem to be a way to delete a disc from the scanned list. So the failed disc scan was creating multple items in that list and I can't delete them.

No search function

This is a nice little app but it lacks the ability to search for files. You can only browse each disk individually. Makes it hard to find things efficiently when I have 20-plus disks catalogued.
