I have my Dropbox account setup on an iMac and a MacBook Air. When I check the folder size of a folder on the Dropbox account in Finder on the iMac it will say the file size is about 45,9 MB while on the MacBook Air it will say 41,4 MB. I can't understand why there is this difference? I've tried to unlink my account and set it up again on my MacBook Air but it's still the same issue.

Is this size of files, or size on disk? What are the sector sizes of the drives? MBA most likely has an SSD, versus an HDD in the iMac, which could be a factor. Have you run rsync in read-only mode to compare the two folders? – user3463 Oct 17 '12 at 20:34
Both computers have SSDs. I'm checking the folder size through the Finder (Apple-I) on the same folder in the Dropbox folder. No I haven't run rsync. I've just done this quick comparison. – Peter Warbo Oct 17 '12 at 20:51
Do both use the same version of OS X? Does it happen to all folders or just one in particular? Can you observe the same thing with single files? Could you post screenshots of the Info window (i.e. press Cmd-I for the folder/file)? – slhck Oct 17 '12 at 20:59
