Browsing through my recent Yosemite backup I noticed that two of the largest files were com.apple.sidebarlists.plist
(78 MB) and com.apple.recentitems.plist
(10 MB). Both files are located in ~/Library/Preferences
.
Investigating com.apple.sidebarlists.plist
yields that the following key holds a huge amount of data under the key: systemitems
> VolumesList
> Bookmark
> data
Is it normal for plist files to become so large? What kind of data is this (icon previews?) and why are the files so large?
