|
This total file may not be included in any other software or |
|
project which presents the data to the public or portions of |
|
the public. Any developer who wishes to include up to (but |
|
not more than) 2,000 individual entries from this file is free |
|
to do so provided certain conditions are met. These are: |
|
. |
|
1) Credit must be given to FILExt. If links are available |
|
in the developed product then one must also be provided to |
|
FILExt as http://filext.com. |
|
. |
|
Suggested text: "File extension list courtesy of FILExt. |
|
For a more extensive list visit http://filext.com." |
|
. |
|
2) Once the extensions are chosen for one product by any |
|
developer then these same extensions must continue to be |
|
used by that developer for any other projects (i.e., you |
|
cannot take one set of 2,000 for one project and a different |
|
set of 2,000 for another project; it's a total of 2,000). |
|
. |
|
3) If links are available in the developed product then any |
|
links appearing associated with any of the 2,000 picked |
|
extensions must be included in the product. (This covers |
|
future plans to include such links in this list.) |
|
. |
|
When the project is complete please notify FILExt with the |
|
specifics at [email protected]. We're always interested |
|
in how the list is being used. Thank you. |
