As you will generally get certain repeating patterns. Admittedly you will only have bit values as opposed to actual symbols or letters.
I'd say we can pretty safely assume that small scale computer devices like an ebook reader and similar would still work in a binary format and generally store stuff in binary formats in part because they are by far the easiest way of storing digital information we have.
Most likely all of the devices will have full-disk encryption (every military device should even now), that alone will be months optimistically. They will not have access to our cryptographic standards, so they won't have any idea of how to even start breaking it, their best hope is that there is a hardware decryption device (like the AES instructions on some Intel chips) that they can find and reverse-engineer, without that they're looking at brute-forcing an unknown system.
Once they figure out the encryption they then have to figure out the file formats, modern file formats are very complex, don't believe me, I just created a Word document containing a single letter a, it's 13kb. All the extra stuff is coding describing how the file works to the software, the Loroi would need to figure that out from scratch. Only plaintext documents would be easy, videos would be virtually impossible until they located and reverse-engineered the codecs, same with music, for documents they'd have to sift through the container to find the content, for pictures they would be facing the same challenge as video and audio unless it's a minimally encoded system like uncompressed bitmaps.
tl;dr, it's going to be a nightmare for whatever Loroi NSA agents get the job of digging through the files
