This is Windows telling you that AxCrypt (acting as ‘you’) does not have permissions to the folder or the file in question. This can be caused by many things, but they are not AxCrypt-related. If you have moved the disk from another Windows-computer or if you have re-installed Windows you may need to “take ownership”. If you have encrypted the files/folder also with Windows EFS (Encrypting File System) *and* moved the files or re-installed Windows, you need to decrypt them in the original Windows or using backed up recovery certificates. Use Google to find out more about the mentioned situations. It is likely you cannot copy and/or delete the file without AxCrypt directly from Windows Explorer either – thus not an AxCrypt-related issue.
