I'm working with a very large file at the moment in PS CC and I'm running into all sorts of problems. The file in question is a .tif of 655mb. It has a resolution of 9425 x 11872 with a dpi of 1200. At first i had some low memory errors. I have 8gb ram and photoshop is using 4700mb. So i increased it so PS now uses 7000mb. I worked on the image but now i can't save it. When i try to save it as .psd i get an error the file size exceeds 2gb. When trying to save as a .tif with layers i get an error the file it exceeds 4gb. When i try to seve it as a .png it simply says "not enough memory to save". Please help!

Your file has gotten larger due to your changes.
And it now exceeds the size limit of many file types.

Try saving as PSB (Large Document Format) to save all the layers and document contents.

And saving as PNG would have thrown away much of the document and just exported the composite image - and yes you would probably need more RAM to save that document to PNG.

I am also currently working a large format file, its takes a long time to save the file.
I have a 8 GB RAM, but no graphics card.  A graphic card will be good for working with large file types.

A better way to increase the speed of saving large files is to go to Preferences>File Handling... and check "Disable compression of PSD and PSB Files"
