How to strip first 3 characters off filename in batch file -


I have some files that I want to strip 3 characters before the file name I thought it would work, But it only outputs: 

  MiSXPRF.Txt ECHO is off ECO is off %% for %%% (% MIS * .tmt)   Close 
 
  @echo (set old name = %% a SET newName =% oldName: ~ 3% echo% Echo% oldName% echo% newName%) pause   
 Note: I am then amending the  REN% aa% newName  Pragya, but I want to make sure that the name is already correct.   
 
 
 You must use a delayed extension to use the variable set in the loop.  
 Try this revised version instead  
  @echo offset Settlelock Enable %% a in (MIS * .tmt) for expansion (old name set Can not have a location in between ==% set newName =  set  and  =  old name: ~ 3! Echo! New name!). >  
 In addition, they should be included.

python - Assemble mpeg file unable to play in mediaplayer -

I am currently working on a school project and I think that is to gather some problems with the MPEG file I The scope of my project is: 1) Split the MPEG file into pieces of many fixed sizes. 2) Collecting some of them and leaving some part.

Problem 2: When I gather the first part off the part, it is unable to run the full MPEG file is. Duration of each piece: 1 second Example: wheel = ["yui_2", "yui_3", "yui_4", "yui_5", "yui_6"...
