- Over 200 formats — open and create compressed files of all the common types.
- Strong encryption — with two-factor protection: a password plus a key file.
- Splitting — break a large archive into parts of a fixed size.
- Hash checks — verify that the file you received is identical to the original.
- Secure deletion — for sensitive files that should leave no trace.
Automation tip
Any task you set up in the interface — for example an encrypted, split archive of a finished project folder — can be exported as a command line and run from a script or the task scheduler. That way archiving is done the same way every time. There is also a portable version that runs with no installation.
