What is short file name creation?
Back in the good ol’ days of windows, filenames were limited to a format of 8 characters for the name, a period, and then 3 characters for a file extension. The filename was limited by FAT formatted partitions. Unless running very old legacy applications, this can be safely turned off to help with performance.
Solution: Complete the following steps below to disable short file name creation.
- Open up an elevated powershell console
- Execute the following command
- Optionally, you can open up registry viewer and confirm the value has been changed.
