Technical Support

This page gives self-service guidance for opening archives, creating ZIP files, using the private vault, and handling common problems.

Offline help

No account and no contact flow are needed; the page itself is the support guide.

Open archives

If an archive will not open

Check that the password is correct.
Make sure all split parts are present.
Try UTF-8, GBK, or GB18030 if filename encoding looks wrong.
Check whether the file is damaged and whether enough storage is available.

Create ZIP

If ZIP creation fails

Make sure the files or folders were selected.
Check that the archive name is valid and the destination can be written.
Review password and split settings if those options are enabled.
When an overwrite prompt appears, choose to replace or keep as needed.

Private vault

On first entry, set a password or use Face ID.
Files can be viewed inside the vault, and exporting them to the local file system may require verification again.
If the password is forgotten, encrypted content is usually not recoverable.

Preview and tools

Image, PDF, text, audio, video, and common document previews are supported.
The tools page is suited for image to PDF, HEIC to JPG, SHA-256, and batch rename.
If nothing appears after import, check whether file access permission has been granted.

Common limits

Damaged archives are not always repairable.
Wrong passwords, bad encodings, or missing split parts can cause failure.
Some formats are preview-only and are not meant for repackaging.
