Automatically Generated Plain Text Versions
The System generates plain text versions of the uploaded materials automatically so that these can be searched easily. The contents of these newly generated files, however, might not completely correspond to their originals since images, tables and some formulae cannot be converted into plain text.

The plain text version is usually shorter than the original and may help the user decide whether he/she will or will not download the unabbreviated original.
When uploading the files of the formats that are not common, you should check the result of their subsequent conversion (it usually takes the newly generated files a few minutes to appear in the folder).
