Lock your private folder

[debashish]

This trick is the safest and locks files or folders without use of any software. 

Suppose you want to lock the folder movies in D: which has the path D:\movies. In the same drive create a text file and type ren movies movies.{21EC2020-3AEA-1069-A2DD-08002B30309D. Now save this text file as loc.bat Create another text file and type in it ren movies.{21EC2020-3AEA-1069-A2DD-08002B30309D} movies. Now save this text file as key.bat. Now you can see 2 batch files loc and key. Press loc and the folder movies will change to control panel and you cannot view its contents. Press key and you will get back your original folder.
     
It is safe as in case if you loose the key file, you can create it again but the folder name must be correct.

Very strong tricks. I think some where you have written ren, it will be run. The .bat file can edit by note pad. When you  lock a file using {21EC2020-3AEA-1069-A2DD-08002B30309D} this the file name will be like {21EC2020-3AEA-1069-A2DD-08002B30309D} this also. If I rename the file name or just leave the "}" from the {21EC2020-3AEA-1069-A2DD-08002B30309D}. The lock file will be lost it's lock & safety.
