As a result of the scan, sometimes it is not possible to recover KEY-TEF files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
A typical compatibility error - the program does not support the older version of the KEY-TEF file. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for the failure. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the ability to automatically repair KEY-TEF file corruption.
The program indicates that the file is encrypted or corrupted. The encrypted KEY-TEF files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.

This problem only occurs with more complex files. In this case, the KEY-TEF file is blocked by the first application to open it. Closing other programs should help. If the error persists after closing other programs, wait for a while. However, some background programs may block the KEY-TEF file while scanning. If this does not work either, restart the device.
