If you are creating a website and need FTP software, FileZilla is a good, free, portable option for a standalone FTP program.

Security and Privacy
TrueCrypt is a very good, free program for encrypting hard drives and creating encrypted vaults for storing your private data. There is a way to create a portable version of TrueCrypt and take it with you on a USB flash drive. However, you can only use the portable version on a PC if you have administrator rights on that PC. FreeOTFE is another option for a program that allows you to create encrypted storage vaults. There is a portable version of FreeOTFE available that does not require administrator rights to use.
Update: TrueCrypt is now defunct. We recommend VeraCrypt instead.
If you need to access private information such as passwords on multiple computers, KeePass provides a good, secure option for storing your private information in a secure database that can be taken with you on a USB flash drive.
LastPass is a great option for securely storing your login information for websites, as well as other personal information. You can also use LastPass to enter your login information on websites automatically. LastPass is portable in the fact that your information is stored online and you can access it from any Windows, Linux, or Mac computer using a web browser extension. Because Firefox, Chrome, and Opera are available as portable programs, you can access your private information almost anywhere. However, what do you do if you don’t have an internet connection? LastPass Pocket allows you to download your LastPass information to a USB flash drive and export into a protected file on that drive. This allows you to access your information without an internet connection.
NOTE: You cannot edit and re-upload information to LastPass using LastPass Pocket. It is mainly to be used for reference.

If you work with your private files on a public computer, you need a way to securely delete any files you copied to that computer temporarily. For several options, see our article about securely deleting files in Windows.
Antivirus & Antispyware
ClamWin is a free, standalone antivirus program for Windows with high detection rates for viruses and spyware. The virus databases are updated on a regular basis. However, you must check for updates manually as the scheduled scans and updates feature is disabled in the portable version.
There are a couple of good portable Antispyware programs you can use to protect your computer. SUPERAntiSpyware provides quick, complete, and custom scanning of many parts of your computer including hard drives, removable drives, memory, and the registry. A portable version is useful, even for your own computer, because many of the worst malware infections block you from installing malware removal software or block it from running if you manage to get it installed. The SUPERAntiSpyware portable scanner is saved under a random filename so that malware infections won’t block the scanner. The free, portable version of SUPERAntiSpyware does not include real-time blocking of threats or automatic updates. You must manually scan your files and check for program and definition updates.
Spybot Search & Destroy detects and removes adware and spyware, dialers, keyloggers, and trojans, as well as fix registry issues and clean usage tracks, which is useful if you share your computer and don’t want other users to see what you’ve been doing. Threats are safely removed by shredding and every problem is backed up.
Your portable flash drive toolkit can include many different system tools as well as other programs.
For compacting and extracting files on the go, there are two free, good tools. 7-Zip is a free, open source file archiver utility for Windows that has a high compression ratio and self-extracting capability for the 7z format and comes with a powerful file manager.
PeaZip is a free file archiver utility that is based on the technology of 7-Zip for handling mainstream archive formats and based on other open source tools (such as FreeARC and UPX) for supporting additional file formats and features such as strong encryption, two factor authentication, encrypted password manager, and secure deletion of files. It is a great all purpose zip utility that is natively portable and cross-platform. Tasks performed in the GUI can be easily saved as batch scripts, allowing you to run automated backups, for example.
For cleaning your Windows PC, CCleaner, from Piriform, is the best tool for the job. It protects your privacy online and makes your computer faster and more secure. It is available in a portable version and is easy to use. It cleans files from web browsers, the Windows system, and includes a registry cleaner for removing unused and old registry entries.
Piriform also makes a good tool for defragging your hard drives, called Defraggler. Use Defraggler to defrag your entire hard drive or individual files. It’s a compact and portable Windows application that supports NTFS and FAT32 file systems. You can schedule Defraggler to run daily, weekly, or monthly. For an option that defrags automatically and quietly in the background, you can use Smart Defrag. It’s always on to continually and constantly keep your computer defragmented. Smart Defrag claims to have the world’s fastest defragmenting engine that’s been designed for modern, large hard drives.
If you are running out of space on your PC or USB flash drive, SpaceSniffer is a portable, freeware program that helps you understand the structure of the folders and files on your disks and where the big folders and files are located. Another tool to help you see what is taking up room on your devices is GetFoldersize. It allows you to see the size of folders and subfolders on your computer’s hard drive or external drives. For each folder, GetFoldersize displays the total file size and the number of files and subfolders in the folder. GetFoldersize is available in a portable version, but the portable version doesn’t support Windows XP without any Service Pack installed and Microsoft Windows 2000.
While using your portable apps on your USB flash drive, you may want to associate file types with the apps on your USB flash drive. If you’re using a computer on which you can’t change the file associations (such as a computer in an internet café or a friend’s computer), you can use a tool, called Portable Extension Warlock (PEW) to create a database of file extensions associated with the portable apps on your USB flash drive. It creates a temporary drop zone on the screen where you can drag and drop files to open them using the associated programs. It’s not the same as double-clicking on a file to open it, but it’s a happy medium between that and having to open the app first and then open the file.
For help with uninstalling programs, there are two good portable options. Revo Uninstaller allows you to use a simplified interface to uninstall programs, even programs causing problems when you try to uninstall them using the Windows Control Panel applet. There are some features that make it easier if you have a lot of software installed. You can reorder the list of programs, list them by icon or detail, like you do for files in Windows Explorer, and even search for programs in the list by name.
ZSoft Uninstaller Portable is another option for uninstalling programs on your computer. It not only replaces the Windows Add/Remove programs feature, but also finds and removes the leftover bits of programs that have been previously uninstalled. ZSoft Uninstaller also allows you to hide entries from the list that you are never going to uninstall (such as drivers), making the list smaller and easier to manage. It also allows you to find and delete temporary files and empty folders.
Note that both Revo Uninstaller Portable and ZSoft Uninstaller Portable require administrative rights to operate.
There are also several options for portable utilities to tweak Windows (Ultimate Windows Tweaker), synchronize, backup, and encrypt your data (Toucan), and create mind maps for brainstorming and organization workflow (Blumind). There is also an easy-to-use alternative to the standard windows file manager, called FreeCommander Portable, with a lot of advanced and helpful features.
If you use the Windows command prompt often, Command Prompt Portable is a simple utility that allows you to have a custom command line setup on any Windows computer.
Portable Linux Software and Distributions
If you want to use Linux but you’re stuck with a Windows computer, you can install a Linux distribution to a USB flash drive so you can run Linux on any PC you come across. Some of the “thumb drive” Linux systems available are Puppy Linux, Damn Small Linux, and Fedora Live USB Creator. Once you set up your portable Linux system, you’ll need some apps for it. PortableLinuxApps is a website that provides portable versions of Linux software that you can install on your thumb drive Linux system.
