<h2>WORKING WITH FILE MASKS</h2> To simplify the life you may organize uploaded files in the groups (folders) using File Masks.<br/><br/> For example files <br/> <i>ac_h0_mfi_20090828_v05.cdf; ac_h0_mfi_20090829_v05.cdf; ac_h0_mfi_20090830_v05.cdf</i> <br/> could be associated with file masks <br/> <b><i>ac_h0_mfi_200908*cdf</i></b> OR <b><i>ac_h0_mfi_2009</i></b> OR <b><i>ac_h0_mfi_</i></b>....etc...<br/><br/> Organization of your files into "mask" folders is made automatically if you introduce a file mask while defining a parameter. Each file could belong to <b>ONE</b> file mask only. If you create a mask more common than existing before all files that fit new mask will be associated with the new mask and old association will be destroyed.<br/><br/> In the above example mask <b><i>ac_h0_mfi_</i></b> is more common than <b><i>ac_h0_mfi_2009</i></b> and <b><i>ac_h0_mfi_200908</i></b> and they will be (where possible) replaced by <b><i>ac_h0_mfi_</i></b>. <br/><br/> <ul><b>Several simple rules:</b> <br/> <li>Mask could include ONE and ONLY ONE "<b>*</b>" symbol <li>Mask should not be shorter than 5 letters <li>Mask should not start with "<b>*</b>" <li>It is prohibited to replace more common mask by less common one. In the above example you cannot replace <b><i>ac_h0_mfi_</i></b> with <b><i>ac_h0_mfi_2009</i></b> or <b><i>ac_h0_mfi_200908</i></b>. <li>Association of different types of files with one mask (ac_h1_mfi..., ac_h2_mfi..., ac_h2_mfi => ac_h) could produce an error. <li>Association of the parameters from one file with different masks produces an error </ul>
