Dropbox and Evernote are wonderful places to store your lesson plans. Drag your class folder into the Dropbox, for example, and then you will be able to open your lesson plan on your iPad or iPhone! Go completely paperless. Make edits to those lessons from anywhere, and they will always be up-to-date! Picture files with text become readable and searchable in any of the applications listed on this page... so after you take a picture of an old lesson plan, you can search the text!
Cost: FREE (multiple platforms)
Download Dropbox to your computer, iPad, iPhone, or Android device - or all of them! Access and edit the same documents from any device, anywhere. Dropbox is an excellent place to keep and share large files (like high resolution photos or even videos) so you don’t have to email them. A great place for group collaboration.
Pros: Create folders to share with colleagues, friends, classes, or independent study students. Documents are updated from any device or platform, and are always up to date. Can also sync between computers, so if you have documents saved on your personal computer that must be shared with a work computer or that of your spouse, all documents are synchronized everywhere!
Cons: No live editing. If you and a friend are editing the same document it creates multiple versions.
Available online, in the App Store and Google Play
You can also use Google Docs or OneDrive to store and share documents, including lesson plans! Both of these systems are wonderful for collaboration, as they have built-in document editors. This means you and a colleague or student can edit the same document at the same time, and you will be able to see edits as they happen! Deleted files are kept intact for 30 days before being permanently deleted (this is also true for Dropbox).

Store photos and docs online. Access them from any PC, Mac or phone. Create and work together on Word, Excel or PowerPoint documents.
Pros: The only service (between Dropbox and Google Drive) that has their own app for Windows phone. You can edit Excel and PowerPoint documents in SkyDrive's web apps. Installing the SkyDrive desktop application allows you to access every file on that PC it is installed in; so as long as your PC is turned on, connected to the internet with SkyDrive running, you’ll be able to access all your files through the SkyDrive website.
