Whether you are a professional or an individual, you have certainly already faced the same problem as me: trying to send a file too large by mail.
But what does "too big" mean?
A file that is too large is a file whose size exceeds the limit supported by your EAP (Email Address Provider).
In general, the maximum size of an attachment to an email can not exceed 25MB, if you use Gmail, Hotmail, Orange or Yahoo for example.
Other EAP, such as Free, AOL and Numericable offer, for their part, a much smaller maximum size, between 10 and 16 MB only.
Now you understand why you can not use your mailbox to send your 20-pages PowerPoint presentation to your colleague, or share the videos and photo albums of your last vacation to all of your friends!
The size of a file increases fast...very fast!
And that's how we step into the wonderful world of Bytes and bits...
And yes, impossible to talk about "file size" without mentioning the particular vocabulary of our computer friends who has some subtleties, where each letter, each capital is important!
Here is the basics to know about computer measurement units:
- The bit (with a lowercase b) means "binary digit". It is the basic unit of the computer measurement system.
- The Byte (with a capital B) corresponds to 8 bits.
Which brings us to:
1 Byte = 8 bits
So, to understand the equivalents, if we take as an example the Giga (whose symbol is "G"), it gives us: 1GB = 8Gb
Now you understand the importance of paying attention to capital and lower case!
Let's go back to our problematic files too heavy.
What are the solutions for sending/sharing large files?
Use a Cloud!
The principle of Cloud is simple: it is sort of a group of remote computers you use the storage space (among others).
These computers are connected to each other and work together to provide hosting services.
Positive point of the cloud: it is available whatever the support you use (smartphone, tablet, computer) and no matter where you are!
Thus, for example, you can transfer your big files (the maximum size differs, depending on the selected cloud) so they can be sent/downloaded by the recipients that you previously selected.
The Cloud allows you to give access to the information you want to share using different channels, such as a mail, an SMS, a link etc.
When you share your data, your recipients then have several days to download your information (NB: the period can be from 24 to 60 days, depending on the chosen cloud).
At the end of this period, your data will be automatically deleted.
Negative point of the cloud: its vulnerability. There is indeed a security risk, since the information you upload is browsing between multiple servers (remember: a cloud uses the services of multiple computers). This risk can however be limited (but not completely removed) through encryption, for example.
Turn your computer into an FTP server!
This is what the O&O FileDirect software offers, among other things.
In addition to being free, this software offers many significant benefits:
- the transfer is really fast
- no registration required or any installation
- the number of recipients is unlimited
- the software generates a link that you then send to the recipients
- you can impose a password for more security
- you choose the expiration time or impose a maximum number of downloads
- your data is not stored anywhere: it is transmitted from your computer directly to your recipients
The downside (because it takes one!) is that this software can only be used through Windows (version 7, 8.1 and 10)...Too bad for MAC users
But O&O FileDirect is far from the only one on the market!
FileZilla, WinSCP, SmartFTP, FTP Traveling and so on: many softwares compete on the internet, you'll be spoiled for choice!
And what about the speed of a large file transfer?
This will depend, of course, on the size of your file, but also (and especially) the flow of the line you use! ADSL or optical fiber: this "detail" is important!
Do not hesitate to browse sites offering to test the flow of your line: it can be usefull!
