What is an H2W file?
An H2W file is a data file created by H2testw, a program used to scan USB drives and SD cards for read and write errors. It contains data generated by H2testw to test a USB drive or SD card. H2W files are created and placed on the drive being tested in order to test the drive's read + write functionality.
To use the H2testw program you first insert the USB drive or SD card, open the program, select the target, choose the data volume, then click. Once the test process is finished the program will display information about the read and write speed of the drive and any errors.
If you come across an H2W file on a drive you can remove it and delete it. However, if you test it with H2testw again another H2W file will be created.
NOTE: H2testw is developed in German but is also available in English.
