I had trouble defragging {dbcbca6a-9a27-11df-94f4-028037000300}{3808876b-c176-4e48-b7ae-04046e6cc752} in C:\System Volume Information using defragler. It is more than 2GB large. Is it normal for one system restore to be that large? Norton and MBAM says the my system is clean. Only 31.1 GB total used. Abou 250 GB (I think) total hard drive space

Also the tracking folder is showing weird characters:
ì§CfþïѲ® ÀO¹8m   windellstudio15 NWÏDc`A¯Ð$±´{ÇÚ =톉eÊ › › ÿÿÿÿ  ›

Defragging does not reduce file size, it only moves files to improve speeds.

Do a disk cleanup maybe its system error storage, or something the operating system stores


Unless it is a virus that is hogging your hard drive space (Inwhich case I would do a scan with Malwarebytes anti malware from malwarebytes.org)
It could be a crucial file, but I would think it would be a bit smaller.

your hard drive has enough space to make that 3 GB look like megabytes....

Keep your eye on that file. If it continually gets bigger, chances are, it could be a virus.

I think it could be system restore as turning off system restore causes the file to dissappear. When I turn it back on, it reappears. Also it used to be 10 GB. I cleared the past restore points and it reduced in size.

Why do you want to defragment a system restore file? It plays no part in normal system operation.

I'm just defragging the whole computer. So it doesn't slow down the computer? Defragler says it has 11% fragments, mostly that one file.

Okay then.
Well, You can limit the space system restore uses. I have mine limited to 50 Gb

I keep my restore down to 1%. All it restores is system configuration files, it is not a backup for pics, etc... so no need to keep it large. the very minimum should be fine.

Agreed, with large drives, the default space allocated for System Restore is much too large, and can be reduced greatly to limit the size of restore files.

There's no discernable benefit from defragmenting the life out of a system - some remnant fragmentation of files that aren't being used during normal system operation (hence won't impact system performance at all) simply isn't worth bothering with.

As it seems you're content to turn system restore off, the simplest way to deal with it would be to turn restore off, re-boot and run the defrag, then turn restore back on. The new restore file might be contiguous, or it might be created in a location that still results in some fragmentation, but really that won't matter at all. In fact, to be pedantic, it is possible that a large moderately fragmented file may reduce free-space fragmentation, which could be seen as a good thing...
