I have a log file that I want to clear each day as part of running a script.  However I get an UnauthorizedAccessException even though the script is running as Administrator and Security on it is Full Control for Everyone

I'm stumped, what do I need to do?

It might be in access by AntiVirus software, or another process. Did you check that yet?

Anti Virus is not the problem, I tried that.   Another process - only process that access it is the one that creates it and I disabled that to see if it was causing the problem, no change in outcome.

Is the file local or on a share?
Are you able to delete/change/rename the file manually?
If loacal, check with Process Explorer or handle.exe (both www.sysinternals.com) whether the file is not open anymore. handle.exe might be easier for that purpose, as you just have to provide a part of the filename to get all open handles for that file.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

Are you able to issue the Clear-Content manually?
If so, the script's autorization has to be the issue.

Then the following shouldn't work either:
"" > C:\logfile
Clear-Content c:\logfile -force

Open in new window

with the proper path and filename, of course.

Overwrite your log file with an empty string - (almost) the same as Clear-Content should do.

Strange. Rename or delete the logfile, and then try each of both commands again, deleting the log file between the test.
We try to find out whether it is file create or overwrite issue.

Don't know what it was.  Deleted file, let it get recreated and bingo it worked.

No restart in between, no changes to security .. it just started working
