Prepare files for conversion
Protect the originals and remove avoidable conversion failures.
- Create a backup or working copy of important source files.
- Close files that are open in another application.
- Remove password protection when you are authorized to do so.
- Separate files by required output when one batch would create conflicting settings.
- Choose a destination with enough free space.
Build the conversion queue
Add compatible files and confirm the intended batch.
- Open All File Converter.
- Choose Add files or Add folder.
- Enable subfolders only when all nested files should be processed.
- Review detected source types.
- Remove unsupported, duplicate, temporary, or unrelated files.
Choose output format and destination
Use an output appropriate to the source and the next business task.
- Choose the available target format for each source family.
- Select a new destination folder instead of overwriting originals.
- Choose whether subfolder structure should be preserved where available.
- Set file-name conflict handling.
- Review the conversion summary before starting.
Run the conversion batch
Keep the utility open while files are processed.
- Start conversion and monitor queued, completed, and failed files.
- Do not disconnect source or destination storage.
- Avoid editing files while they are being converted.
- Open the error detail for any failed source.
- Retry only after correcting access, format, or source-file problems.
Validate converted files
A completed status does not guarantee perfect visual or functional fidelity.
- Open representative output files in their normal application.
- Check text, fonts, page breaks, tables, images, formulas, links, and embedded content.
- Compare important totals or values with the source.
- Review every high-value or client-facing document.
- Keep the originals until the converted set is accepted.
Macros, complex layouts, protected content, embedded media, and unsupported features may not convert exactly.
Organize the completed batch
Keep source, output, and error records easy to distinguish.
- Move validated output into the approved delivery or archive location.
- Keep failed items in a separate review folder.
- Record the source and target formats used for repeatable work.
- Remove temporary output after acceptance.
- Retain originals according to the organization policy.
Troubleshooting notes
Common questions that can save a support request.
Why did formatting change?
The source may use fonts, layout features, macros, embedded content, or application-specific behavior that the target format cannot reproduce exactly.
Why did one file fail while similar files converted?
The file may be damaged, protected, incomplete, in use, mislabeled, or contain an unsupported feature. Open it in the source application and save a clean copy.
