What is "System Volume Information" ?

Recommended Posts

After analyzing the 'C' drive using Defraggler the list of files that are fragmented includes several VERY large files with unusual names within brackets {} {} including hex chars and hyphens. The paths to these files are all the same : C:\System Volume Information. However when displaying the contents of 'C:\' there are no fldrs or files that even come close to the names shown by Defraggler. If these files are not needed are they candidates for deletion ? Any ideas ? Thanx.

System Volume Information contents files created by System Restore, files created by indexing files and others perhaps.


I formatted my drives in FAT32 ,so, I open them with a double-click.


If we format in NTFS, we can also, after a changes the properties's folder, tab "Security". You must choose which controls the folder.


Be careful, do not delete anything, there might be the case.


Best Regards

By the way Bob - welcome to the forum.


as Hazel said, turn them off from being included in DF.

they are used if you ever need to go back to a previous Restore Point.

if you have Restore Points turned off, the folder should be empty.

Hi, Mta,


if you have Restore Points turned off, the folder is not necessarily empty. There necessarily the files:




There may also be files created by indexing files. (Cidaemon.exe and cisvc.exe) If the drive is formatted in NTFS, of course; In FAT32, file indexing does not exist.

I'm sure because I changed the security of this folder in my NTFS drives.


Best regards
