How to Check Mixed DOCX, PPTX, Photos, and Videos for Corruption After Moving Them to a New Computer
Moving files to a new computer creates two separate questions: did the transfer copy the bytes correctly, and were the original files healthy in the first place? That distinction is exactly what a user raised in this r/datarecovery post about moving roughly 7,000 files, including DOCX, PPTX, photos, videos, and other formats from an older laptop.
Check Each File Type with the Application That Actually Uses It
- Step 1
Open representative DOCX and PPTX files and confirm that text, images, slide objects, and formatting render correctly.
- Step 2
Open full-resolution photos and inspect them beyond the thumbnail preview.
- Step 3
Play videos from start to finish or at least sample the beginning, middle, and end to catch decode or truncation problems.
- Step 4
Prioritize important folders first, then expand the check to representative samples from the remaining collection.
Do Not Confuse a Transfer Check with a Corruption Check
A checksum can show that the destination matches the source file, but it cannot tell you whether the source file was already corrupted before the move. If a supported document is present with plausible data but fails to open, Repairit File Repair can be tested on a copy of that specific file.
Before Resetting the Old Computer:
Keep the original storage until your priority documents and media have been opened and validated. If a failed file is empty or obviously incomplete, return to recovery; if it contains data but is structurally damaged, repair may be appropriate.
