안전하게 임시 파일 지우기 

Running out of disk space? This week's tip hands you a batch file for safely deleting unneeded temp files. 
Safely removing temporary files 
C++Builder eats up disk space; a small project can generate 5 MB 
of temporary files! The compiler and the incremental linker use 
these *.il?, *.csm and *.tds files. But when those files become 
corrupt, you get the "Unknown Error #1" message. 

You can delete the offending files any time with no ill effects. 
However, if you delete them manually you might accidentally delete 
a file you need. Instead, you can write a small batch file and add 
it to the C++Builder Tools menu. First create a small batch file 
like this: 

C:\BCBDEL.BAT:
del %1*.tds 
del %1*.il? 
del %1*.csm 
del %1*.obj

Next, choose Tools | Configure Tools... and click the Add button. 
In the Tool Properties dialog box, set the Title property to 
"Clean-Up", the Program property to "C:\BCBDEL.BAT", and the 
Parameters property to "$PATH()". 

If you get an Unknown Error #1 message, select Tools | Clean-Up 
and exit C++Builder; then start it up again. If you still get the 
error, delete the temporary files in the Cbuilder\bin directory 
(using BCBDel.Bat) and restart Windows.
