What do the phrases 'EDC' and 'No EDC' mean on PSX files?

Hi, this is a great site!

I need some advice about PSX1 images please. I am currently starting to set up my Raspberry Pi 2 as a Retropie console, using an external SSD drive to store the game images. I have noticed that some images have 'EDC' and 'No EDC' against them - what does this mean and how does it affect the image? I want to be sure to obtain the one best suited to my Retropie setup. I did search, but I got no hits for 'EDC'.

Well known term to Disc Dumpers.

If you want the best images possible you want Redump, I have quite a few Redump images here in the forum.

Just check the masterlist and search for the word Redump.
