How to Fix High SSD Space Usage Consumed with ETL Files

First and foremost, what is ETL? ETL stands for Event Tracking Log. It is a binary file format that captures log information from a variety of built-in Windows tools and diagnostic utilities.

Windows 10 usually keeps most of ETL files. You can find the number of ETL files (between 700 and 2000) on various Windows 10 computers though Voidtools Everything. Here are some tips on checking Windows 10 ETL files.

  • Keeping ETL files is not necessary. You don’t have to keep ETL files around. If you have a lot of them, it may cost you some time to figure out where logging should be turned on (and what should be turned off).
  • Most ETL files are protected or exist in protected directories. You can nearly delete all of these files by running Explorer (or Everything) as administrator. If all the other methods don’t work, please boot from a bootable media to enter the BIOS and delete the files with Command Prompt in the Windows Recovery Environment.
  • Most ETL files are small, but a few of them are very large. In this case, you can free up more space by deleting these big files.

Based on these tips, you can decide whether you need to delete these ETL files or not. Of course, if you are not sure whether the content is important, make a backup before deleting it.

Deleting ETL files is an effective method to free up SSD space, but you can also upgrade to larger hard drive to fix the space not enough issue. If you don’t want to delete ETL files in case you lose valuable data, upgrading to a larger hard drive is a great choice for you. In this way, you are able to save more other files on the SSD drive in addition to these space-consumed ETL files.
