FAQ:

1) How to find duplicate files?

From “Storage Reports”, select “File list Sorted by Size” Report to get list of files sorted by size. Duplicate files usually appear next to each other.

2) Does not encrypt as stated.
Encryption creates NEW file with .enc extension. Unencrypted original file is left as it is. You have to delete original unencrypted file after encrypting the file.
Example: Original file name: abc.txt, after encryption abc.txt.enc is created. After this you will see both abc.txt and abc.txt.enc files.
You have to delete abc.txt after successful encryption. Un-encrypting abc.txt.enc file recreates abc.txt.
Note: You must remember the password to decrypt the file.
3) After compressing a file/folder storage space size increased!

Compressing a file or folder creates compressed file with .zip extension. You have to delete the folder or file manually after compression to free up space.
Example : Compressing folder name foo creates foo.zip. You have to manually delete foo folder to free up space. You can uncompress foo.zip to recreate foo folder.
