# LZFSE Archiver Support

LZFSE Archiver compresses and decompresses files with Apple's LZFSE algorithm.
Support is provided by email without a guaranteed response time or
emergency-service availability.

## A file cannot be opened

- Confirm that the source still exists and that Files or Finder grants access.
- A compressed file normally uses the **.lzfse** extension. A differently named
  file may not be recognized as a decompression input.
- Try copying cloud-hosted input to a local folder before opening it again.

## Output cannot be written

Choose a destination with enough free space and write permission. On Mac,
select the destination folder again if its saved permission is stale. Existing
files are not overwritten automatically; rename or move the old output first.

## Cancel or clear an operation

Cancel stops the current operation and removes incomplete output where
possible. Clear removes completed entries and temporary in-app output, but it
does not delete files already saved to a user-selected destination.

## Remove app data

Delete source and output files with Files or Finder. Removing LZFSE Archiver
deletes its local temporary files, preferences, and stored Mac folder
bookmarks.

## Privacy

The [Privacy Policy](https://flaviothomi.com/lzfse-archiver/privacy/) explains
local file processing, temporary output, and macOS folder bookmarks.

## Contact

Include the app version, operating-system version, device model, operation,
file size, file extension, destination type, and exact error text. Do not send
the source file unless support requests a safe sample. Contact
[support@flaviothomi.com](mailto:support@flaviothomi.com?subject=LZFSE%20Archiver%20Support&body=Hi%20Flavio%0A%0A).
