hard drive space lost after creating a session

I have two hard drives,Drive (C) and (E)

I create the session location using drive (E) to import all the raw data from the flash card. I typically brinh in about 4 GB of raw files form the cf. I noticed that I loose about 0.8 GB on (C) drive. this happens after I import put the raw files in the folder (E) assigned to that session.

I guess my question is, why do I loose 0.8 GB on my C drive when my session is on the E Drive and would I recover that space after I am done working and deleting that session and all it's files-of couse I do back-up all my raw on dvd.

I am assuming the 0.8 gb is the thumbnails created for all these photos imported!! if so where are they stored if they are not deleted after I am done with the session and delete all it's files.

thank you
RCK

  RCK,
  
  The volume is being used by the Preview Cache.
  Within the cache are the Thumbnails or Work files (.C1w), but these are only 1KB
  Most space would be used by the Previews (.C1p) which vary with camera model but in general are about 1/3 or so of the RAW file size.
  Preferences > Prefiew Cache >
  
  When you are done with a Session, remove it from Capture One and then in the Preferences you can clean-up the cache.
  Once Session is removed, the Previews won't rebuild.
  The .C1w remains, but again they are only 1KB and contain all the image adjustment data.
  If you want to save these data, then the .C1w files must be archived.
  Workflow > Selected capture settings > Save to archive
  Save then along with the RAWs works well.
  
  Cheers,
  K C

  Thank you for the respond,
  
  so I can only delete these files via (clean cache) only? I should never delete these file manualy from the folder. I can only delete them or clean the cache after I am done with the sessions not before?
  
  thank you

  You can delete the .c1p files by hand (I wouldn't do it while Capture One is running, but any other time is OK). The .c1w files store your image settings, so I wouldn't touch those (they are very small anyway).
  
  Even if you delete .c1p files of a session on which you are still working, Capture One will recreate the needed files the next time it is started. Nothing to worry about there.
