Everyone should be familiar with the file encryption function that comes with the Windows system, but when we actually operate it, some friends will choose the encrypted content on their computer to protect the data, it is grayed out, and there is no way to check it.
In fact, the encryption function that comes with Windows is still somewhat limited:
First of all, only files on NTFS partitions can be encrypted, and files on FAT partitions cannot be encrypted.
Second, files marked with the "system" attribute cannot be encrypted, and files located in the systemroot directory structure cannot be encrypted either.
Finally, Windows Encryption doesn't work with Windows Home Editions, only Professional Editions.
First check whether your encrypted files and system version are in these conditions.
If not, but still can't encrypt files, you can try the following methods:
First Windows + R enter regedit
In the registry, click HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Control \ FileSystem, then find NtfsDisableEncryption, double-click it, adjust the value data to 0, and click OK. After setting, check whether you can use the Windows encryption function.
If you think it is too troublesome to operate, you can also enter cmd during operation, open the command window, enter fsutil behavior set disableencryption 0, and set it through the command.
After the Windows encryption system is replaced, the files encrypted by the original system cannot be decrypted, so in addition to the file encryption function that comes with Windows, we can also use encryption software to encrypt files. More, support multiple files, folder encryption, support limit the number of times to open files.
You don't need to worry about decrypting or forgetting the password, as long as you ensure that the account number when encrypting and decrypting the file is the same, it supports one-click decryption of the file password.
