If your VPS or DS is running out of space, a common cause is MetaTrader storing large numbers of log files over time. These files record platform activity for troubleshooting and history purposes, but they are not required for normal day-to-day trading.
You can safely delete old MetaTrader log files. When MetaTrader starts again, it will automatically create new empty log files as needed.
When this helps
This cleanup is useful when:
your VPS reports low disk space
MetaTrader has been running for a long time
you use Expert Advisors or scripts that generate many entries
you run strategy tests or backtesting, which can create especially large log folders
Step 1: Open the MetaTrader data folder
Open your MT4 or MT5 platform.
Select File from the top-left menu.
Choose Open Data Folder.
A folder window will open showing the MetaTrader data location.
Step 2: Delete the log files
There are three main places where MetaTrader log files are usually stored. In each location below, delete the files inside the folder.
Location | Where to find it | What to do |
|---|---|---|
Main logs | Open the logs folder | Select all files inside and delete them |
EA logs | Go back to the main folder, then open MQL4 or MQL5, then open Logs | Select all files inside and delete them |
Tester logs | Go back to the main folder, then open tester, then open logs | Select all files inside and delete them |
Tester logs are often the biggest files, especially if you have been running backtests.
Important note
Deleting these logs will not remove your trading account, charts, indicators, Expert Advisors, or platform settings. It only removes old recorded activity.
After deleting the files, you should have more free space available immediately. If needed, restart MetaTrader to continue working normally.
