Acronis True Image 2018 Active Protection Left Overs Fix (large ContentFile.BLOB)
I tried Acronis True Image 2018 out and during the trial I tried out the ransomware protection module "Active Protection".
After trying out Acronis True Image 2018 I uninstalled it and it left over 10GB of ContentFile.BLOB files on C Drive.
The issue at that point is that no matter what I tried I could not delete them (permissions issue).
I found a fix and am posting it here for people's access :D You do need to be a bit of a nerd and be confident in the Windows command prompt.
NB: You'll need to be logged in as a user with Admin permissions.
SECTION 1: Identifying Files
1) Create a restore point and appropriate disk backup to external drives first, just in case.
2) Uninstall Acronis True Image 2018 (if not already uninstalled)
3) Install and run Search Everything (https://www.voidtools.com) and open to a search [sorted by Size] of: C:\ "ContentFile.BLOB" size:>200MB
e.g.
4) For very large files listed, right click them each and copy-paste their full path into a text file for later use
SECTION 2: Running Commands
[VITAL: Replace each mention of Dean with your Windows Username. e.g. George OR "George S"]
A) Run the Command Prompt as an Administrator
B) Give permissions to the System Volume Information folder by running the command: ICACLS "C:\system volume information" /grant Dean:F
C) Give permissions to the folder's contents by running the command: ICACLS "C:\system volume information" /grant Dean:F /T
D) Run the actual force delete command(s) on the full path(s) we copied in section 1 as: DEL /f "FULLPATHGOESHERE"
e.g. DEL /f "C:\System Volume Information\FileProtector\FileStorage\0A9E379F-EED6-492A-85D6-8EBFF8109C25\15\F8\5531E6E532CB41963FC2C2218EBA\ContentFile.BLOB"
E) Revoke permissions to the System Volume Information folder by running the command: ICACLS "C:\system volume information" /remove Dean /T
F) Revoke permissions to the folder's contents by running the command: ICACLS "C:\System Volume Information" /remove Dean
After all that it should look similar to:
Now restart your PC and check your C Drive disk space in Windows Explorer :D
