Cannot delete some things, but still great.
I used this program to help me clean up a bunch of hard drives from dead computers I have had for over 15 years.
Im rough on my Macs, so when it dies I just get a new one and start fresh, carrying over only what I need. This left me with a bunch of drives filled with videos and pics and music and important docs and a WHOLE LOT OF JUNK.
And this software was terrific at sorting it all out. I used a cheapie USB 2 to SATA adapter for the drives.
It would be 5 stars but for a minor quibble, and that is probably an Apple security issue rather than a problem with the app. I couldn’t change ownership of some of the old files and as a result, some duplicate files could be found, but not deleted, by the app. Thankfully, most of the time there is a way to immediately open a finder window to see the files, and you can just trash them manually after confirming an ADMIN password, and even if the button for opening the finder window doesn’t show up ( sometimes it didn’t for some reason) you can just follow the path and get rid of things that way.
An excellent app. Saved me hours and days.
I had dulicate music files all over, it seemed I’d never straighten it out. DFF works great for telling me what is duplicated & where to go to clean it up. It will try to do this for you but it’s very tedious to go song-by-song as it wants to. It did speed up a nagging chore from a weekend to one evening & for that it is well worth the price. If you hesitate to buy, ask yourself "How valuable is my time?” No brainer for me.
I’d give it 5 stars if it were a little more intuitive on pattern matching the names of files such as song titles. As I said though, well worth the price.
This thing actually works!
I have tried at least 1/2 dozen dup file apps….I paid for Gemini 2 and never did get it complete a scan on an 8TB drive and two 2TB drives.
For $5 this did the job! And it was much faster than the other ones I tried. This ones did not eat up my 16GB of RAM and kill my mac like Gemini 2 did.
Thanks or making software that actuall works! Pay the $5 you will be happy you did!
