Yes, wiping free space is quite intensive, as it overwrites the entire free space (unallocated data area) of the drive, e.g. CCleaner can help protect against this by wiping the free space with its Drive Wiper tool.
File recovery programs can scan your hard disk for these files, and, if the operating system hasn't written over the area, can recover the data. But they will either be all zeroes or small zero files. After a WFS Recuva will still list all these deleted records, with file names which may be valid or not, and these files can be recovered (in as much as the files overwritten data can be retrieved). When I would sell my computer, I would feel safer if I used some program for advanced wiping. Instead, the pointers to the files are deleted and the operating system marks the file's location as free space. A WFS may - depending on the settings - overwrite the file names in the MFTs records.
