1. Notepad++ - This open source product, is probably the best editor out there. I am using it for several years , and I use it even for a single file. If you are working with multiple files ( like I do ), then the multi tabbed interface lets you switch back and forth . Its support for various programming language , diff / merge , XML Syntax editor and several other cool features doubles itself as the preferred programmers editor. If there was a plugin which could open *sln, *.mak files , then it might give Slickedit a stiff competition.
2. Q-Dir - How many times have you toggled between several Windows Explores , just to find the files(s) you were looking for . In my work place I need to have several of them open, as I have to look into several documents simultaneously . Couple of days back, while surfing the web, I found this excellent freeware and from the first day, I'm lovin' it. Moreover it has a very low memory footprint.
RecentX and its a handy tool too.
3. Foxit Reader - I had been using Acrobat Reader till yesterday, was not happy with it because of the memory it takes , and sometimes irritated by the update notifications. Therefore I decided to opt for a lightweight pdf reader , and found Foxit reader a good alternative. This reader has a small memory footprint, but does the job neatly.
4. GMail - I have stopped using email clients at home , from last month ; as I realized GMail itself has lots of potential. GMail integrated with the Tasks and GCalendar, itself makes a very useful dashboard. Earlier I had tried OtherInbox, Remember The Milk , but if one uses the in built features properly I think other addons are a redundant.
5. Join Me - This is a screen sharing program, which requires ONLY a browser , necessary software is installed automatically once you share the screen . I have been impressed with TeamViewer, Mikogo , Crossloop , but Join Me is the only web based screen sharing I have come across, and so this is my pick. I recently had a three way conference using Join Me.
6. Stickies - Sticky notes are a good way to manage your TODO list or for keeping side notes on your desktop. I had started looking for a freeware, and this is the best free sticky notes I have come across. Notezilla, a paid sticky note software is an excellent alternative with extra features.
7. Jing - Jing is an excellent freeware, which allows you to take screenshots, make videos, and share instantly with the collaborators .It is a product by Techsmith ; the company which develops SnagIt .
8. SlickRun - This is another extremely handy utility which can be used for launching programs, web sites. One can also add their MagicWords to customise SlickRun.
