You just need to keep track whether file is already read into DB or not.

For this purpose you need do :--

1. first create a column(field) to your table to hold the file name which are already read
probably you already have such field.

2. Whenever you copy a file to DB first check if it is not already in the table

if yes
     then do nothing just go next in the loop

if not
     put the absolute path of file into DB
     copy the file into DB in your own way.

Here is an example for FileSystemWatcher
C#: Application to Watch a File or Directory using FileSystem Watcher[^]

Two excellent libraries for dealing with Excel:
Excel Data Reader - Read Excel files in .NET[^]

EPPlus[^]

It will hopefully et you started ...

Very useful links.

Well, thank you Marcus :)

Espen, my 5.
Just a note on first reference: the article itself is not very good. Perhaps, just one line would be enough: use System.IO.FileSystemWatcher. This .NET class is a very good thing, but the production design relying on this is very bad.

Thanks SAKryukov, the article was short, and that often seems to satisfy people more than a long treatise.
