Interesting open source alternatives for handling online meetings, videos, screenshots, and files:
- DimDim, an open-source free alternative for online collaboration (paid comparison: WebEx)
- CamStudio, an open-source free limited AVI screen recorder and AVI-SWF converter (paid comparison: Camtasia)
- MWSnap, a free alternative for basic screen captures (paid comparison: Snagit)
- CutePDF, free print-to-PDF software (paid comparison: Adobe, Win2Pdf, etc)
- FileZilla, open-source free alternative for FTP and sFTP (paid comparison: SmartFTP, WS_FTP, etc)
- CrossLoop, free remote screen sharing app (paid comparison: CoPilot, GoToAssist)
You get what you pay for: these free versions are far more limited than their full-featured commercial cousins.
However, depending on which particular features you need, sometimes they suffice.
They also provide an easy, no-cost, first step into these categories.
