I have an iMac running Mac OSX 10.5.8, I know, going to upgrade after I repair this issue, with your help. My startup disc is full and this has obviously started giving me fits in many ways. Luckily I have had an external HDD attached through a USB port and have had "Time Machine" running in the background. Now I have been paranoid using the Apple system because I am an old Windows user and I cannot see allot of what is going on in the background. I had taken to putting new photos in folders on the desktop, like I would have done with Windows. I have also been copying them to the external HDD as I was afraid that I could never get them back without restoring using time machine, and I always worry what other changes are being made I cannot see. When I saw that my Startup Disc was full I began to drag files into the trash, mostly pictures, but some large files as well. The startup disc is still full because I have not emptied the trash, of course. NOW I am paranoid to empty the trash because I am afraid that the photos and files are linked into the external HDD and that it will delete access to them forever too. I can't be sure what is going on in the background. I drug a pic out of the trash and couldn't double click on it to see it, but when I tried to drag it to iPhoto it opened and I could see that I have allot of pics still in iPhoto even though I thought I drug all photos into the trash. Are all my pics in iPhoto, and even if I empty the trash, they are still on the hard drive. Maybe since they are in iPhoto, and on the desktop they are taking up double the startup disc space. I am seriously starting to hate apple now and I need your help to unravel this mess. I checked online to see about buying iCloud to put all my photos on the cloud and then delete, but I have to buy a newer operating system. I cannot do that until I resolve this disc space issue I am sure. For a moment I clicked on empty trash and it came up that there was some 270,000 files to delete and it was doing so very slowly, probably take days do empty the trash. there is not way I have that many files in the trash. Please help me as this is overwhelming at this time and I used to build computers and used Windows since DOS and 3.11 on floppy's.
