Why do COP files take so much space?
I am clearing out the digital digital detritus from Phasewnd COP files. They are littered through my hard drive and take up an inordinate amount of space.
490MB of COP files for 1.1 gb of CR2s?
Just wondering why they take up so much room. I didn't make edits to a lot of those files.

Just make a test...opened a folder with 500 megs of PEF files, browse through it without any modification, closed C4 - added 50 megs of cop files...
seems too much..0 -
The .COP files contain the preview. Their contents is static. If deleted, they will be regenerated next time you open the folder with images. Your adjustments are stored in the (smaller) .COS files.
These .COP files, although eating up disk space, are much smaller than the CO3.x preview files (which were often larger than the raw file itself). This remained unnoticed by many users of CO3, since these preview files were stored in a difficult to find folder under the Program Files folder.
The advantage of preview files is that (re-)use of the image in preview is very fast once generated (generation of preview is much faster in CO4 compared in previous CO versions).
In short: previews are part of a fast working raw converter.
Feature request: deletion of preview COP files at will or if older than x days (like in CO3, Preferences)0 -
I think I read a PO response somewhere in this forum in the past week which also said that v4 previews are a higher quality than their v3 counterparts.
Whilst the v3 ones were larger, at least v3 had a Preferences setting which gave the user control of which drive/folder they are placed in! Any v3 user who considered them "hidden" had obviously not dabbled much with the program at all - I would've thought that most v3 users had gone into the Preferences for one reason or another.0
