9- How to delete many object files at the same time.
The use of this tutorial is at your own risks. Read it once
up to the end before trying anything.
The first version of DecoTech
has been released in 1992, three years before the release of Windows
95 and its long file name support. So this is why we have decided
to create our own long file name support to bypass the old
8.3 file name format. That has been a great innovation at that time
but today all that looks obsolete.
A DecoTech data file is saved under an
arbitrary hexadecimal file name composed of 8 characters. The real file name
is directly stored inside
each file. We have also incorporated the possibility to add
a comment to each DecoTech data files. (Up to now, even the most
recent version of Windows does not have this feature yet.)
To speed up the display of folder contents,
we have created catalog-index files ("dskcat.idx") in each
data folder. Each "dskcat.idx" file contains all the
bits hexadecimal file names present in the same folder and the
corresponding real file names and comments. Each
"dskcat.idx" file is automatically created ONLY
when you use a
Requester to display the contents of a specific folder.
Also, all the "dskcat.idx" files are automatically deleted in
all the folders when you install new add-ons or when you run the
Library Installer Program
To view the contents of a "dskcat.idx"
file, we have created a small program named IDX Lister Program
Each time you will run this program, you will need to specify a "dskcat.idx"
file. If you want to make its use easier, you can specify a
file as second argument when running the program. To do so you have two possibilities :
Associated the ".IDX"
extension with "....\DecoTech\bin\psidxlst.exe".
After that, simply double-click on each "dskcat.idx" you want to
In the "C:\Documents and
folder created a shortcut with a command line set to "....\DecoTech\bin\psidxlst.exe"
and name it IDX Lister. After
that, simply right-click on
each "dskcat.idx" you want to view and select the
menu and the IDX Lister submenu.
(For Windows Vista and Win7 use "C:\Users\<Username>\AppData\Microsoft\Windows\SendTo\")
You can do multiple selections
by using the SHIFT and/or CTRL keys. The Copy button copies
the selected text lines into the clipboard to let you paste them into a word processing
program by example. The Erase button permanently
deletes the selected data files. When you use the
button, the current "dskcat.idx" file is also delete
because the IDX Lister Program
is only a viewer and it is not able to update the "dskcat.idx"
file. By doing that, the
Requester or the
Requester will automatically recreate the "dskcat.idx"
file and their display will be updated.
