Many dev_*.old files on OS level

[Former Member]

Dear community,

I have had very many files dev_*.old at the OS level. Can I just delete them? Or need to turn off SAP?

Hi,

dev_*.old file is developer trace for work processes. It become "old" after SAP instance restarted where new developer trace are generated.

If space is not a issue, you can leave it there. After dev_*.old trace will be overwritten everytime SAP instance restarted.

Thanks,
