Ignore unwanted files to appear in SVN Status list

You can set ignore property for directories under SVN to ignore specific file or a group using wildcard.

Here are few examples:
svn propset svn:ignore '*' .
Run this command inside a directory to ignore all the files inside it. It is best suited for cache directory where you want the cache folder to be inside SVN since it is a part if the structure but do not want unwanted files and directories in it.

svn propset svn:ignore changelog.txt .
This will ignore changelog.txt file to appear in svn status list.

svn propset svn:ignore “*.tmp” .
Ignore all file with tmp extension.

svn propset svn:ignore -R 'Thumbs.db
Thumbs.db:encryptable' .
Thumbs.db & Thumbs.db:encryptable are files that gets created when you open a directory in windows machines and it has few images in it. These files always come up in your svn status list and create problem. The command will solve the problem. The -R Option is to set the property recursively down to all the directories.
Note: Multiple file name must be inside quotes and should be separated by new line.

Backup your Firefox Extentions and bookmarks.

I generally take a backup of the extensions and bookmark of my Firefox to synchronize the setting between my home computer and the computer at my work place.

You will need to install an extension FEBE(Firefox Environment Backup Extension). This extension after installation will create a menu under tools and provides you with lot of backup options, in those options you have extension backup and bookmark backup.

Here is a link where you can download the latest version of

There is another extension CLEO(Compact Library Extension Organizer) that can be used to combine all the extension and make it as a single extension file. it can also be very help full if you have your own custom made extension.

Here is a link where you can download the latest version of CLEO

Shifting my computer application settings

Recently I had to to reinstall OS on my computer. It is a time taking task and every time I do it I always forget to take backup of few application settings. So I had to create a check list of application whose settings I need to save before reinstalling the OS.

Here is the list I prepared.
1. Firefox bookmarks and extensions.
2. Putty configurations.
3. Webdav configurations.
4. Desktop and Documents.
5. Copy Favorites directory under you profile.
6. Copy all important files from the OS installation drive.

Webdav has a backup option which will backup all the setting in a reg file.
