Deleted files not purged by the system
When I got notified by TechTool that my Flash Disk runs out of space I started to look what happens. First I moved big files to an external drive and deleted them on the Flash Disk. After doing so for some 10 GB the warning remained. I started to analyze if I can recuperate space using TechTool or CleanMyMac but the alert of TechTool remained.
I selected the Flash Disk and opened the information window that showed the low free space in the row for available. In parallel I launched „About this Mac“ and looked on the Volumes. The shown free space was the same as in the information window.
Only switching in „About this Mac“ to an other item and back to the Volumes the free space had increased by a big portion.
A few moments later in the information window the entry for available changed to the same high value as in „About this Mac“ but with an additional entry for space that is purgable. Subtracting this value delivered the old low value of available space.
Restarting „About this Mac“ delivered the forth view where „About this Mac“ shows the low available space and the information window the two values of available and purgable.
Now the questions:
- How can I purge the data that is shown as purgable?
- What can I do that the system will purge deleted files in the future?
- Since one of the last system updates the system generates an empty folder „#recovers file“ in the basked with each log off. Is this connected?
