Is it possible to download a large file in smaller parts over ftp?

[jan verschueren]

I was wondering if it was possible to download a large txt file from an ftp server in smaller parts.

For example download a file of 1GB into 2 files of 500 MB.

Is this possible without having to download 1 GB in one time?

Heya jan verschueren, welcome back to bytes.

Short answer: Not to my knowledge.

Long answer: It may be possible but now with FTP; It's too dump to actually manipulate files, unless of course you write your own FTP software to do this.

Perhaps using HTTP it maybe possible.

1. Read the file name
2. Read fractions into one or more new file
3. Provide links for these new files

Then the user must put humpty dumpty back together again.

Thanks for the advice.

I will look into using http for reading the file. Building my own revolutionary ftp software is a bit out of my range :)

If all went well, i will post the working version here. Thanks

Strange - I thought I'd already replied to this thread.

Anyway, file_get_conten ts allows you to specify offset and length of the file to download.

Can you really use ftp:// with file_get_conten ts?

I've never tried but I know http:// works.

I'd be interested in seeing a working test script of connect to the ftp, finding the total size of file and downloading it in chunks and putting it back together.

Anyone free and have spare time on their hands?

From php.net/file-get-contents:

Tip

A URL can be used as a filename with this function if the fopen wrappers have been enabled. See fopen() for more details on how to specify the filename. See the List of Supported Protocols/Wrappers for links to information about what abilities the various wrappers have, notes on their usage, and information on any predefined variables they may provide.
