Android invalid command-line parameter: Files\Android\android-sdk\tools/emulator-arm.exe

I don't know how this problem happen. Anyway before last update everything ran perfectly. But after the update and when i try to run the emulator i found this issue:

invalid command-line parameter: Files\Android\android-sdk\tools/emulator-arm.exe.
Hint: use '@foo' to launch a virtual device named 'foo'.
please use -help for more information


After several checks i found that Android not supports any spaces in between the folder path. Because in previous it's "C:\Program Files\Android\android-sdk " and now i set it as "C:\Android\android-sdk" (cut and paste to C: root)

Also changed the eclipse android SDK path as "C:\Android\android-sdk"

After change the directory structure it's working. I don't know Y?
