Hello Jörg,
The location(C:\Users\’user name’\AppData\Local\AxCrypt) is for the temporary copies of the files. Those will either be cleaned automatically at the earliest opportunity or when you click the red clean “broom” icon in AxCrypt.
AxCrypt works by decrypting files temporarily and then launching the appropriate application for the decrypted file, which thus is entirely unaware of AxCrypt. AxCrypt monitors the system for the launched app to exit, and when it detects this it will re-encrypt the file and wipe (overwrite) the decrypted file and then delete it.
Please close the encrypted file and the corresponding file, Actually, we have to close the file opened application completely, to update and re-encrypt the file. Sometimes, we have to manually click the red Broom icon, to clean and update the pending files.
Note: The temporary files will be removed as soon as the opened encrypted file is closed/signed out from the AxCrypt app.
If you have any questions, please write an email to support@axcrypt.net.
