I normally use a tool like WinZip, 7Zip, or WinRAR to create zip files but I'm on a Windows 7 system that doesn't have these tools installed (and I can't install new apps).
Outside of 3rd party tools like the above, can I create (or modify) a zip file in Windows 7 and request that it be password protected? (the files would contain sensitive information that I plan to transmit to another PC)*
e.g. the process I'm familiar with on Windows is to select the files, right click and choose: "Send to..." > "Compressed (zipped) folder" - but there doesn't seem to be any additional options.
* Note: I'm aware this isn't 100% secure, locked down mega encryption - just looking for "reasonable effort" to secure the data in transit.
