Unable to copy files from file system to IntelliJ IDEA 10.5

I have just started using IntelliJ IDEA.I am really novice to this IDE, so please bear if my question sounds silly.

I am facing a problem regarding copyin开发者_StackOverflow社区g of files from OS's File explorer to IntelliJ Project.

I am using following versions:

Operating System: Ubuntu v. 11.04

IntelliJ IDEA: v. 10.5.1

JDK: v. 1.6.0_27

For e.g. in the following image I have created a project having a Maven module.

I am unable to copy a schema file (.xsd) on my file system into the folder ..../src/main/conf/vehAvailRate.I tried out so many times but the file is not getting copied.Also I tried the Synchronize feature too but that too didn't helped.However when I open the project in file system and copy my desired schema file there ,IntelliJ IDEA relfects the change.

Am I doing something wrong or there is some other reason behind this behavior?

Thanks,

Jignesh

Such copy should be performed externally, using your favorite file manager. IDEA will refresh files under its project directory automatically.

If something goes wrong, check idea.log file in ~/.IntelliJIdea10/system/log directory.
