Extract text from H2testw or watch face files (H2W)
To convert H2W Watch face files to another format, you need H2testw or other System software.
To convert other file formats to the "Storage Media Test File" file type, you need software like H2testw or a similar tool.
The .H2W file extension is predominantly a storage media test file generated by H2testw, a popular data integrity tool. When a user tests an SD card, SSD, or USB flash drive for fake capacities or hardware faults, the software fills the available space with sequentially numbered .H2W files (e.g., 1.h2w, 2.h2w), each typically 1GB in size. These files contain pseudo-random data used strictly to verify read and write operations.
A secondary, less common use for the .H2W extension is the Huawei Watch Face File. These proprietary files are used to customize the display of Huawei smartwatches.
Users frequently encounter issues with .H2W files. If generated by H2testw, they consume massive amounts of disk space (up to the entire drive's capacity) and contain no actual user data. You do not need to convert these; you simply need to delete them once the hardware test is complete. However, if dealing with a Huawei Watch Face .H2W file, the format is proprietary and locked to Huawei's wearable ecosystem. Modifying them requires specialized community tools to extract internal assets like PNG images or XML layouts.
Because .H2W can mean either useless test data or a proprietary smartwatch skin, standard online converters completely fail to process it. Just drag and drop your file onto convert.guru to identify the format, view it, and convert it when possible. If our analysis detects an underlying embedded format (like images within a watch face archive), viewing or conversion to standard formats like ZIP or PNG may still be possible.
Convert.Guru analyzes your H2W file, detects the exact format, and lets you read the text inside.
Users also converted ZIP, EDOC, ADOC, CRDOWNLOAD, ASO, SLC and TOC files.
If you want to convert H2W file to TMP, TEMP, CACHE, LOG, BAK, OLD, NEW, PART, DOWNLOAD, CRDOWNLOAD, LOCK or PID, you can use H2testw or similar software from the "Data Integrity Testing" category. In the File menu, look for Save As… or Export….
To convert DEVICE, CACHE, SOCK, SYMLINK, PID, MOUNT, FIFO, LOG, PIPE, TMP, JUNCTION or TEMP files to H2W, try H2testw or another comparable tool in the "Data Integrity Testing" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our H2W converter.
