Before transmitting the contents of the file itself, the file has to be assigned a unique 64-bit client identifier: file_id.

The file's binary content is then split into parts. All parts must have the same size (part_size) and the following conditions must be met:

The last part does not have to satisfy these conditions, provided its size is less than part_size.

Each part should have a sequence number, file_part, with a value ranging from 0 to the value of one of the following appConfig fields minus 1:

The following appConfig fields specify the maximum number of uploadable file parts:

Note that the limit of uploadable file parts does not account for the part_size: thus the total file size limit can only be reached with the biggest possible part_size of 512KB, which is actually the recommended part_size to avoid excessive protocol overhead.

Each part should have a sequence number, file_part, with a value ranging from 0 to the value of the appropriate config parameter minus 1.

After the file has been partitioned you need to choose a method for saving it on the server. Use upload.saveBigFilePart in case the full size of the file is more than 10 MB and upload.saveFilePart for smaller files.

Each call saves a portion of the data in a temporary location on the server to be used later. The storage life of each portion of data is between several minutes and several hours (depending on how busy the storage area is). After this time, the file part will become unavailable. To increase the time efficiency of a file save operation, we recommend using a call queue, so X pieces of the file are being saved at any given moment in time. Each successful operation to save a part invokes the method call to save the next part. The value of X can be tuned to achieve maximum performance.

When using one of the methods mentioned above to save file parts, one of the following data input errors may be returned:

    While the parts are being uploaded, an MD5 hash of the file contents can also be computed to be used later as the md5_checksum parameter in the inputFile constructor (since it is checked only by the server, for encrypted secret chat files it must be generated from the encrypted file).
    After the entire file is successfully saved, the final method may be called and passed the generated inputFile object. In case the upload.saveBigFilePart method is used, the inputFileBig constructor must be passed, in other cases use inputFile.
