Manage files is a personal inbox where you can store all of your converted files. You can use it to rename,
delete, re-convert or download any of your files. You can also, if you wish, send your files onto
friends using the share functionality.
- How can I search my files ?
Within the manage files page we have given you the ability to search for files. The search is
based on a wildcard search, therefore any part of the file name you enter will look at all your files
and return anything with your search criteria entered. For example if you entered "doc", this would
return all files with doc, therefore all of your doc files. Similarly if you entered "fun", and you had
three files within your inbox with the letters fun within there filename, then these would be returned.

When you choose to delete files from within your inbox these are permanently deleted from our servers,
therefore you are requested to proceed with caution when deleting files from your inbox.

Should you wish to rename any of your files, then we have offered this functionality within the
manage files page. Against each file you will see a rename option, once you select this the filename
box will become editable and you can change the name. Next to this box you will see cancel and save options
should you cancel the box will become uneditable and the filename will revert to what it was previously.
Should you save, the filename you have entered within the box will be the new filename.

You can now share your file links with friends by selecting the share option. Use the "copy link" button to

- "Zamzar" is kind of a weird name - Where does it come from ?
The name "Zamzar" is based on a character from the German author Franz Kafka's book "The Metamorphosis". In the novel Kafka describes
the extraordinary story of a young man who is transformed whilst sleeping into a gigantic insect. The man's name - Gregor Samsa - was
used as the basis for our company name because of its' powerful association with change & transformation.
