, I'm currently downloading photos and movies from my iphone which we know immediately puts them in iphoto library.
Only if you use iPhoto. If you use Image Capture you can put them anywhere you want.
Its stopped half way saying I've run out of space.
Regardless of whatever method you use you now have a major problem.
OS X needs about 10 gigs of hard drive space for normal OS operations - things like virtual memory, temporary files and so on.
Without this space your Mac will slow down as the OS hunts for space on the disk, files will be fragmented, also slowing things down, apps will crash and the risk of data corruption - that is damage to your files, photos, music - increases exponentially.
Your first priority is to make more space on that HD. Nothing else can be done until you do.
Purchase an external HD and move your Photos and Music to it. Both iPhoto and iTunes can run perfectly well with the Library on an external disk.
To move an iPhoto Library:
Make sure the drive is formatted Mac OS Extended (Journaled)
1. Quit iPhoto
2. Copy the iPhoto Library from your Pictures Folder to the External Disk.
3. Hold down the option (or alt) key while launching iPhoto. From the resulting menu select 'Choose Library' and navigate to the new location. From that point on this will be the default location of your library.
4. Test the library and when you're sure all is well, trash the one on your internal HD to free up space.
Can one have a maximum amount of images in iphoto ?
Yes. With iPhoto that amount id 1,000,000
I've just checked the size of library and its saying 115.66GB ! - this is only about 5010 items,
That sounds excessive. Do you have many large videos in there?
Even if I manage to copy all to a separate hard drive, how can I or should I remove from original folders.
Let's get this absolutely clear. If you move the Library the question is redundant. However, no one, not me, not Keith Doherty is saying anything about removing from the original folders. Keith takes about copying images out of there, I suggest exporting. No one is suggesting removing and doing so will corrupt your Library.
