Sparsebundle file size - no more free space
I have a MacBook Pro with 250gb. Today I copied videos, music and personal files from my iMac 24 to my desktop on MacBook Pro to afterward move them to the correct location. But I don't know why, when a file is in the desktop and you move it to a folder, it's always copied and not moved.
I tried using the command key together and some filer were moved but I noticed that actually it's a copy and then delete it from original location. Anyway, my issue started once I was doing this "move" with the command and the system said no free space. So I checked and from the 250gb I had only 8gb left.
All the files that I was copying were 160gb and I had already 20gb used previously. So I decided to delete the files from Desktop, plug my external HD again and now move to the correct location each folder. But, the same free space was showing up. I had already cleaned the trash and the same free space was showing up. So I thought was something on the mac's memory. So I booted it twice, I booted using the safe mode to scan for errors on the HD, I shut it down for 1 day and nothing changed.
So I used a tool called GrandPerspective to find about files on the HD. And than I found a file with 163GB on my .username folder, under the library (that's a hidden folder). This file is huge, so i thought it's something related to backup as with this size, that's the only option, it keeps everything that goes to the mac and was deleted.
So now I'm here, stuck and with this huge file that I can't delete and I don't know how to reduce its size. I'm not using time machine bkp on this notebook.
Does someone have an idea about what to do?
