Are you sure about this – that the temporary files remain even after the red broom icon is cleared or AxCrypt is exited? AxCrypt does indeed temporarily decrypt the files to the location in question, and then open them from there. Once you are done, or exit AxCrypt, they will be overwritten and deleted (after re-encryption if required). This is at least how it is designed to work.
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.
AxCrypt will create a random temporary folder under the specified path to keep the decrypted copy of the encrypted file. The location(C:\Users\’user name’\ .local ▸ share…) is for the temporary decrypted 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.
Note: The temporary files will be removed as soon as the opened encrypted file closed/signed out from the AxCrypt app
