What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Verify a video archive in three separate passes: compare SHA-256 checksums with the original files, use ffprobe to inspect each file’s container and streams, then test playback through the actual URL and client you plan to use. The first two checks catch different problems; neither proves that the VPS’s serving path works.
1. Compare each VPS file with its source using SHA-256
A matching digest establishes that the destination file is byte-for-byte identical to the particular source file you compared. It does not prove that the source itself is complete or playable. GNU Coreutils documents checksum generation and verification as a way to detect corruption and supports SHA-2 digests. See the GNU Coreutils 9.11 checksum documentation.
-
On the machine holding the original archive, generate a SHA-256 digest for each video. With GNU Coreutils, run
sha256sum -- path/to/video.mp4. Record the output alongside the source path and filename. -
After uploading, run the same command on the VPS against the corresponding destination file:
sha256sum -- /path/to/video.mp4. Use the same algorithm and ensure the source and destination paths refer to the intended files.The Tool Desk

Compare the full digest strings. They must match exactly. For a batch, GNU Coreutils can check a saved digest file with
sha256sum --check checksums.sha256; create and use the record with paths that resolve correctly in the directory where you run the check.
If a digest does not match
Do not mark that destination file as verified. First confirm that you compared the intended source and destination, including filenames and paths. If they correspond, re-upload the file or investigate the transfer and storage before proceeding, then calculate and compare the digests again.

2. Inspect the media with ffprobe
A checksum checks identity against a source; it does not explain what is inside a file. Use ffprobe to see whether FFmpeg can open the input and identify its container and streams. The FFprobe documentation describes stream and container inspection, structured output, error reporting, and version reporting. It also notes that ffprobe returns a positive exit code when an input cannot be opened or recognized as multimedia.

Check that ffprobe is available and record the version with
ffprobe -version.Free tools Windows power users keep installed

Probe a file in a human-readable form with
ffprobe -hide_banner /path/to/video.mp4. Review the reported container and streams, including the video and audio streams you expect to be present. -
For a saved report or automated checks, request JSON output:
ffprobe -v error -show_format -show_streams -of json /path/to/video.mp4. Save the output with the file’s path and the time of the check. -
Check the command’s exit status as well as its output. An input that cannot be opened or recognized is not a successful probe; inspect the error and verify the path and file before treating it as ready.

What a successful probe does—and does not—tell you
A successful probe means the tool could identify media structure; it does not certify that every part of the file decodes correctly, that the intended player supports its codecs, or that a web server or streaming application is configured correctly. Treat it as an inspection step, not an end-to-end playback test.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errors3. Test the real serving path and a client
Once the digest matches and the probe is useful, test the file through the same URL and delivery path that viewers or your streaming application will use. Open or play it from a client that represents the intended use. A local probe cannot establish that the URL is reachable, that permissions allow access, or that playback succeeds over the configured path.

4. Keep an audit record
For each archive item, retain the source and destination paths, filename, SHA-256 values and comparison result, ffprobe output, tool versions, and check timestamps. GNU Coreutils supports generating and checking digest records; ffprobe supports structured output and version reporting. These records make it possible to identify exactly which file and tool results you relied on when approving an archive for use.
